README

Welcome to the Stark Infra PHP SDK! This tool is made for PHP developers who want to easily integrate with our API. This SDK version is compatible with the Stark Infra API v2.

Introduction

Index

Supported PHP Versions

This library supports the following PHP versions:

  • PHP 7.1
  • PHP 7.2
  • PHP 7.3
  • PHP 7.4
  • PHP 8.0
  • PHP 8.1

Stark Infra API documentation

Feel free to take a look at our API docs.

Versioning

This project adheres to the following versioning pattern:

Given a version number MAJOR.MINOR.PATCH, increment:

  • MAJOR version when the API version is incremented. This may include backwards incompatible changes;
  • MINOR version when breaking changes are introduced OR new functionalities are added in a backwards compatible manner;
  • PATCH version when backwards compatible bug fixes are implemented.

Setup

1. Install our SDK

1.1 Composer: To install the package with Composer, run:

composer require starkinfra/sdk

To use the bindings, use following the command:

require_once('vendor/autoload.php');

2. Create your Private and Public Keys

We use ECDSA. That means you need to generate a secp256k1 private key to sign your requests to our API, and register your public key with us, so we can validate those requests.

You can use one of following methods:

2.1. Check out the options in our tutorial.

2.2. Use our SDK:

use StarkInfra;

list($privateKey, $publicKey) = StarkInfra\Key::create();

# or, to also save .pem files in a specific path
list($privateKey, $publicKey) = StarkInfra\Key::create("file/keys/");

NOTE: When you are creating new credentials, it is recommended that you create the keys inside the infrastructure that will use it, in order to avoid risky internet transmissions of your private-key. Then you can export the public-key alone to the computer where it will be used in the new Project creation.

3. Register your user credentials

You can interact directly with our API using two types of users: Projects and Organizations.

  • Projects are workspace-specific users, that is, they are bound to the workspaces they are created in. One workspace can have multiple Projects.
  • Organizations are general users that control your entire organization. They can control all your Workspaces and even create new ones. The Organization is bound to your company's tax ID only. Since this user is unique in your entire organization, only one credential can be linked to it.

3.1. To create a Project in Sandbox:

3.1.1. Log into StarkInfra Sandbox

3.1.2. Go to Menu > Integrations

3.1.3. Click on the "New Project" button

3.1.4. Create a Project: Give it a name and upload the public key you created in section 2

3.1.5. After creating the Project, get its Project ID

3.1.6. Use the Project ID and private key to create the object below:

use StarkInfra;

// Get your private key from an environment variable or an encrypted database.
// This is only an example of a private key content. You should use your own key.
$privateKeyContent = "
-----BEGIN EC PARAMETERS-----
BgUrgQQACg==
-----END EC PARAMETERS-----
-----BEGIN EC PRIVATE KEY-----
MHQCAQEEIMCwW74H6egQkTiz87WDvLNm7fK/cA+ctA2vg/bbHx3woAcGBSuBBAAK
oUQDQgAE0iaeEHEgr3oTbCfh8U2L+r7zoaeOX964xaAnND5jATGpD/tHec6Oe9U1
IF16ZoTVt1FzZ8WkYQ3XomRD4HS13A==
-----END EC PRIVATE KEY-----
";

$project = new StarkInfra\Project([
    "environment" => "sandbox",
    "id" => "5656565656565656",
    "privateKey" => $privateKeyContent
]);

3.2. To create Organization credentials in Sandbox:

3.2.1. Log into StarkInfra Sandbox

3.2.2. Go to Menu > Integrations

3.2.3. Click on the "Organization public key" button

3.2.4. Upload the public key you created in section 2 (only a legal representative of the organization can upload the public key)

3.2.5. Click on your profile picture and then on the "Organization" menu to get the Organization ID

3.2.6. Use the Organization ID and private key to create the object below:

use StarkInfra;

// Get your private key from an environment variable or an encrypted database.
// This is only an example of a private key content. You should use your own key.
$privateKeyContent = "
-----BEGIN EC PARAMETERS-----
BgUrgQQACg==
-----END EC PARAMETERS-----
-----BEGIN EC PRIVATE KEY-----
MHQCAQEEIMCwW74H6egQkTiz87WDvLNm7fK/cA+ctA2vg/bbHx3woAcGBSuBBAAK
oUQDQgAE0iaeEHEgr3oTbCfh8U2L+r7zoaeOX964xaAnND5jATGpD/tHec6Oe9U1
IF16ZoTVt1FzZ8WkYQ3XomRD4HS13A==
-----END EC PRIVATE KEY-----
";

$organization = new StarkInfra\Organization([
    "environment" => "sandbox",
    "id" => "5656565656565656",
    "privateKey" => $privateKeyContent,
    "workspaceId" => null // You only need to set the workspaceId when you are operating a specific workspaceId
]);

// To dynamically use your organization credentials in a specific workspaceId,
// you can use the Organization::replace() method:
$balance = StarkInfra\IssuingBalance::get(StarkInfra\Organization::replace($organization, "4848484848484848"));

NOTE 1: Never hard-code your private key. Get it from an environment variable or an encrypted database.

NOTE 2: We support 'sandbox' and 'production' as environments.

NOTE 3: The credentials you registered in sandbox do not exist in production and vice versa.

4. Setting up the user

There are three kinds of users that can access our API: Organization, Project and Member.

  • Project and Organization are designed for integrations and are the ones meant for our SDKs.
  • Member is the one you use when you log into our webpage with your e-mail.

There are two ways to inform the user to the SDK:

4.1 Passing the user as argument in all functions:

use StarkInfra;

$balance = StarkInfra\IssuingBalance::get($project);  # or organization

4.2 Set it as a default user in the SDK:

use StarkInfra;

StarkInfra\Settings::setUser($project);  # or organization

$balance = StarkInfra\IssuingBalance::get();  # or organization

Just select the way of passing the user that is more convenient to you. On all following examples we will assume a default user has been set.

5. Setting up the error language

The error language can also be set in the same way as the default user:

use StarkInfra;

StarkInfra\Settings::setLanguage("en-US");

Language options are "en-US" for english and "pt-BR" for brazilian portuguese. English is default.

Resource listing and manual pagination

Almost all SDK resources provide a query and a page function.

  • The query function provides a straight forward way to efficiently iterate through all results that match the filters you inform, seamlessly retrieving the next batch of elements from the API only when you reach the end of the current batch. If you are not worried about data volume or processing time, this is the way to go.
use StarkInfra;

$transactions = StarkInfra\IssuingTransaction::query([
    "after" => "2020-01-01",
    "before" => "2020-03-01"
]);

foreach ($transactions as $transaction) {
    print_r($transaction);
}
  • The page function gives you full control over the API pagination. With each function call, you receive up to 100 results and the cursor to retrieve the next batch of elements. This allows you to stop your queries and pick up from where you left off whenever it is convenient. When there are no more elements to be retrieved, the returned cursor will be null.
use StarkInfra;

$cursor = null;
while (true) { 
    list($page, $cursor) = StarkInfra\IssuingTransaction::page($options = ["limit" => 5, "cursor" => $cursor]);
    foreach ($page as $transaction) {
        print_r($transaction);
    }
    if ($cursor == null) {
        break;
    }
}

To simplify the following SDK examples, we will only use the query function, but feel free to use page instead.

Testing in Sandbox

Your initial balance is zero. For many operations in Stark Infra, you'll need funds in your account, which can be added to your balance by creating a starkbank.Invoice.

In the Sandbox environment, most of the created starkbank.Invoices will be automatically paid, so there's nothing else you need to do to add funds to your account. Just create a few starkbank.Invoices and wait around a bit.

In Production, you (or one of your clients) will need to actually pay this starkbank.Invoice for the value to be credited to your account.

Usage

Here are a few examples on how to use the SDK. If you have any doubts, check out the function or class docstring to get more info or go straight to our [API docs].

Issuing

Query IssuingProducts

To take a look at the sub-issuer card products available to you, just run the following:

use StarkInfra\IssuingProduct;

$products = IssuingProduct::query();

foreach ($products as $product) {
    print_r($product);
}

This will tell which card products and card number prefixes you have at your disposal.

Create IssuingHolders

You can create card holders to which your cards will be bound. They support spending rules that will apply to all underlying cards.

use StarkInfra\IssuingHolder;

$holders = IssuingHolder::create([
    new IssuingHolder([
        "name" => "Iron Bank S.A.",
        "taxId" => "012.345.678-90",
        "externalId" => "1234",
        "tags" => [
            "Traveler Employee"
        ],
        "rules" => [
            new StarkInfra\IssuingRule([
                "name" => "General USD",
                "interval" => "day",
                "amount" => 100000,
                "currencyCode" => "USD"
            ])
        ]

            new StarkInfra\IssuingRule([
                "name" => "general",
                "interval" => "week",
                "amount" => 50000,
                "currencyCode" => "USD"

Process Purchase Authorizations

It's easy to process purchase authorizations delivered to your endpoint. Remember to pass the signature header so the SDK can make sure it's StarkInfra that sent you the event. If you do not approve or decline the authorization within 2 seconds, the authorization will be denied.

use StarkInfra\IssuingPurchase;

$request = listen();  # this is your handler to listen for authorization requests

$purchase = IssuingPurchase::parse(
    $request->content, 
    $request->headers["Digital-Signature"]
);

# after parsing you should analyse the authorization request and then respond

# To approve:
sendResponse(  # you should also implement this method to respond the read request
    IssuingPurchase::response([
        "status" => "approved",
    ]);
);

# To deny:
sendResponse(  # you should also implement this method to respond the read request

    "search" => "token"
]);

foreach ($methods as $method) {
    print_r($method);
}

Pix

Create PixRequests

You can create a Pix request to transfer money from one of your users to anyone else:

use StarkInfra\PixRequest;
use StarkInfra\Utils\EndToEndId;

$requests = PixRequest::create([

DynamicBrcodes represent charges with information that can change at any time, since all data needed for the payment is requested dynamically to an URL stored in the BR Code. Stark Infra will receive the GET request and forward it to your registered endpoint with a GET request containing the UUID of the BR code for identification.

use StarkInfra\DynamicBrcode;

$brcodes = DynamicBrcode::create([
    new DynamicBrcode([
        "name" => "Jamie Lannister",

print_r($brcode);

Verify a DynamicBrcode Read

When a DynamicBrcode is read by your user, a GET request will be made to the URL stored in the DynamicBrcode to retrieve additional information needed to complete the transaction. Use this method to verify the authenticity of a GET request received at your registered endpoint. If the provided digital signature does not check out with the Stark public key, a StarkInfra\Exception\InvalidSignatureException will be raised.

use StarkInfra\DynamicBrcode;

$request = listen();  # this is the method you made to get the read requests posted to your registered endpoint

$uuid = DynamicBrcode::verify(
    $request->content, 
    $request->headers["Digital-Signature"]
);

Answer to a Due DynamicBrcode Read

When a Due DynamicBrcode is read by your user, a GET request containing the BR code UUID will be made to your registered URL to retrieve additional information needed to complete the transaction.

The GET request must be answered within 5 seconds, with a HTTP status code 200, and in the following format.

use StarkInfra\DynamicBrcode;

$request = listen();  # this is the method you made to get the read requests posted to your registered endpoint

$uuid = DynamicBrcode::verify(
    getUuid($request->url),  # you should implement this method to extract the UUID from the request's URL
    $request->headers["Digital-Signature"]
);

$invoice = getInvoice($uuid); # you should implement this method to get information on the BR code from its uuid

sendResponse(  # you should also implement this method to respond the read request
    DynamicBrcode::responseDue([
        "version" => $invoice->version,
        "created" => $invoice->created,
        "due" => $invoice->due,
        "keyId" => $invoice->keyId,
        "status" => $invoice->status,
        "reconciliationId" => $invoice->reconciliationId,
        "amount" => $invoice->amount,
        "senderName" => $invoice->senderName,
        "receiverName" => $invoice->receiverName,
        "receiverStreetLine" => $invoice->receiverStreetLine,
        "receiverCity" => $invoice->receiverCity,
        "receiverStateCode" => $invoice->receiverStateCode,
        "receiverZipCode" => $invoice->receiverZipCode
    ]);
);

Answer to an Instant DynamicBrcode read

When an instant DynamicBrcode is read by your user, a GET request containing the BR code's UUID will be made to your registered URL to retrieve additional information needed to complete the transaction.

The GET request must be answered within 5 seconds, with a HTTP status code 200, and in the following format.

use StarkInfra\DynamicBrcode;

$request = listen();  # this is the method you made to get the read requests posted to your registered endpoint

$uuid = DynamicBrcode::verify(
    getUuid($request->url),  # you should implement this method to extract the uuid from the request's URL
    $request->headers["Digital-Signature"]
);

$invoice = getInvoice($uuid); # you should implement this method to get the information of the BR code from its uuid

sendResponse(  # you should also implement this method to respond the read request
    DynamicBrcode::responseDue([
        "version" => $invoice->version,
        "created" => $invoice->created,
        "keyId" => $invoice->keyId,
        "status" => $invoice->status,
        "reconciliationid" => $invoice->reconciliationId,
        "amount" => $invoice->amount,
        "cashierType" => $invoice->cashierType,
        "cashierBankCode" => $invoice->cashierBankCode,
        "cashAmount" => $invoice->cashAmount
    ]);
);

Create BrcodePreviews

You can create BrcodePreviews to preview BR Codes before paying them.

use StarkInfra\BrcodePreview;

$previews = BrcodePreview::create([
    new BrcodePreview([
        "id" => "00020126420014br.gov.bcb.pix0120nedstark@hotmail.com52040000530398654075000.005802BR5909Ned Stark6014Rio de Janeiro621605126674869738606304FF71",
        "payerId" => "123.456.780-01"
    ]),
    new BrcodePreview([
        "id" => "00020126430014br.gov.bcb.pix0121aryastark@hotmail.com5204000053039865406100.005802BR5910Arya Stark6014Rio de Janeiro6216051262678188104863042BA4",
        "payerId" => "123.456.780-01"
    ])
]);

foreach ($previews as $preview) {
    print_r($preview);
}

Lending

If you want to establish a lending operation, you can use Stark Infra to create a CCB contract. This will enable your business to lend money without requiring a banking license, as long as you use a Credit Fund or Securitization company.

The required steps to initiate the operation are:

  1. Have funds in your Credit Fund or Securitization account
  2. Request the creation of an Identity Check for the credit receiver (make sure you have their documents and express authorization)
  3. (Optional) Create a Credit Simulation with the desired installment plan to display information for the credit receiver
  4. Create a Credit Note with the desired installment plan

Create CreditNotes

For lending operations, you can create a CreditNote to generate a CCB contract.

Note that you must have recently created an identity check for that same Tax ID before being able to create a credit operation for them.

use StarkInfra\CreditNote;
use StarkInfra\CreditSigner;
use StarkInfra\CreditNote\Invoice;
use StarkInfra\CreditNote\Transfer;

$notes = CreditNote::create([
    new CreditNote([
        "templateId" => "0123456789101112",
        "name" => "Jamie Lannister",
        "taxId" => "012.345.678-90",
        "nominalAmount" => 100000,
        "scheduled" => "2022-05-11",
        "payment" => new Transfer([
            "bankCode" => "00000000",
            "branchCode" => "1234",
            "accountNumber" => "129340-1",
            "taxId" => "012.345.678-90", 
            "name" => "Jamie Lannister"
        ]),
        "paymentType" => "transfer",
        "invoices" =>[
            new Invoice([
                "amount" => 120000,
                "due" => "2022-07-11",
                "fine" => 3.0,
                "interest" => 1.0
            ])
        ], 
        "signers" =>[
            new CreditSigner([
                "contact" =>  "jamie.lannister@gmail.com",
                "method" => "link",
                "name" => "Jamie Lannister",
            ])
        ],
        "rebateAmount" => 0,
        "tags" => [
            'War supply',
            'Invoice #1234'
        ],
        "externalId" => "my_unique_id",
        "streetLine1" => "Av. Paulista, 200",
        "streetLine2" => "10 andar",
        "district" => "Bela Vista",
        "city" => "Sao Paulo",
        "stateCode" => "SP",
        "zipCode" => "01310-000"
    ]);
]);

foreach($notes as $note){
    print_r($note);
}

Note: Instead of using CreditNote objects, you can also pass each element in dictionary format

Query CreditNotes

You can query multiple Credit Notes according to filters.

use StarkInfra\CreditNote;

$notes = CreditNote::query([
    "limit" => 10,
    "after" => "2020-04-01",
    "before" => "2020-04-30",
    "status" => "signed",
]);

foreach($notes as $note){
    print_r($note);
}

Get a CreditNote

After its creation, information on a Credit Note may be retrieved by its id.

use StarkInfra\CreditNote;

$note = CreditNote::get("5155966664310784");

print_r($note);

Cancel a CreditNote

You can cancel a Credit Note if it has not been signed yet.

use StarkInfra\CreditNote;

$note = CreditNote::cancel("5155966664310784");

print_r($note);

Query CreditNote logs

You can query Credit Note logs to better understand credit note life cycles.

use StarkInfra\CreditNote\Log;

$logs = Log::query(["limit" => 10]);

foreach($logs as $log){
    print_r($log);
}

Get a CreditNote log

You can also get a specific log by its id.

use StarkInfra\CreditNote\Log;

$log = Log::get("5155966664310784");

print_r($log);

Create CreditPreviews

You can preview a credit operation before creating them (Currently we only have CreditNote / CCB previews):

use StarkInfra\CreditPreview;
use StarkInfra\CreditNote\Invoice;

$previews = CreditPreview::create([
    new CreditPreview([
        "type" => "credit-note",
        "credit" => new CreditPreview\CreditNotePreview([

            "type" => "sac"
        ])
    ]),
    new CreditPreview([
        "type" => "credit-note",
        "credit" => new CreditPreview\CreditNotePreview([

    ]),
]);

foreach($previews as $preview){
    print_r($preview);
}

Note: Instead of using CreditPreview objects, you can also pass each element in dictionary format

Create CreditHolmes

Before you request a credit operation, you may want to check previous credit operations the credit receiver has taken.

For that, open up a CreditHolmes investigation to receive information on all debts and credit operations registered for that individual or company inside the Central Bank's SCR.

use StarkInfra\CreditHolmes;

$holmes = CreditHolmes::create([
    new CreditHolmes([
        "taxId" => "012.345.678-90",
        "competence" => "2022-09"
    ]),
    new CreditHolmes([
        "taxId" => "012.345.678-90",
        "competence" => "2022-08"
    ]),
    new CreditHolmes([
        "taxId" => "012.345.678-90",
        "competence" => "2022-07"
    ]);
]);

foreach($holmes as $sherlock){
    print_r($sherlock);
}

Query CreditHolmes

You can query multiple CreditHolmes according to filters.

use StarkInfra\CreditHolmes;

$holmes = CreditHolmes::query([
    "after" => "2020-04-01",
    "before" => "2020-04-30",
    "status" => "success",
]);

foreach($holmes as $sherlock){
    print_r($sherlock);
}

Get a CreditHolmes

After its creation, information on a CreditHolmes may be retrieved by its id.

use StarkInfra\CreditHolmes;

$logs = CreditHolmes::get("5155165527080960");

print_r($log);

Query CreditHolmes logs

You can query CreditHolmes logs to better understand their life cycles.

use StarkInfra\CreditHolmes\Log;

$logs = Log::query([
    "limit" => 10,
    "ids" => ["5729405850615808"],
    "after" => "2020-04-01",
    "before" => "2020-04-30",
    "types" => ["created"]
]);

foreach($logs as $log){
    print_r($log);
}

Get a CreditHolmes log

You can also get a specific log by its id.

use StarkInfra\CreditHolmes\Log;

$logs = CreditHolmes\Log::get("5155165527080960");

print_r($log);

Identity

Several operations, especially credit ones, require that the identity of a person or business is validated beforehand.

Identities are validated according to the following sequence:

  1. The Identity resource is created for a specific Tax ID
  2. Documents are attached to the Identity resource
  3. The Identity resource is updated to indicate that all documents have been attached
  4. The Identity is sent for validation and returns a webhook notification to reflect the success or failure of the operation

Create IndividualIdentities

You can create an IndividualIdentity to validate a document of a natural person

use StarkInfra\IndividualIdentity;

$identities = IndividualIdentity::create([
    new IndividualIdentity([
        "name" => "Walter White",
        "taxId" => "012.345.678-90",
        "tags" =>["breaking", "bad"]
    ]);
]);

foreach($identities as $identity){
    print_r($identity);
}

Note: Instead of using IndividualIdentity objects, you can also pass each element in dictionary format

Query IndividualIdentity

You can query multiple individual identities according to filters.

use StarkInfra\IndividualIdentity;

$identities = IndividualIdentity::query([
    "limit" => 10,
    "after" => "2020-04-01",
    "before" => "2020-04-30",
    "status" => "success",
    "tags" =>["breaking", "bad"]
]);

foreach($identities as $identity){
    print_r($identity);
}

Update an IndividualIdentity

You can update a specific identity status to "processing" for send it to validation.

use StarkInfra\IndividualIdentity;

$identity = IndividualIdentity::update(
    "5155165527080960",
    "processing"
)

print_r($identity)

Note: Before sending your individual identity to validation by patching its status, you must send all the required documents using the create method of the CreditDocument resource. Note that you must reference the individual identity in the create method of the CreditDocument resource by its id.

Cancel an IndividualIdentity

You can cancel an individual identity before updating its status to processing.

use StarkInfra\IndividualIdentity;

$identity = IndividualIdentity::cancel("5155165527080960");

$documents = IndividualDocument::create([
    new IndividualDocument([
        "type" => "identity-front",
        "content" => "data:image/jpeg;base64,/9j/4AAQSkZJRgABAQAASABIAAD...",
        "identityId" => "5155165527080960",
        "tags" => ["breaking", "bad"]
    ]),
    new IndividualDocument([

To create a Webhook and be notified whenever an event occurs, run:

use StarkInfra\Webhook;

$webhook = Webhook::create(
    new Webhook(
        "url" => "https://webhook.site/",
        "subscriptions" =>[
            "credit-note"
            "issuing-card", "issuing-invoice", "issuing-purchase",
            "pix-request.in", "pix-request.out", "pix-reversal.in", "pix-reversal.out", "pix-claim", "pix-key", "pix-infraction", "pix-chargeback"
        ]
    );
);

print_r($webhook);

Query webhooks

To search for registered Webhooks, run:

use StarkInfra\Webhook;

$webhooks = Webhook::query();

foreach($webhooks as $webhook){
    print_r($webhook);
}

Get a webhook

You can get a specific Webhook by its id.

use StarkInfra\Webhook;

print_r($webhook);

Delete a webhook

You can also delete a specific Webhook by its id.

use StarkInfra\Webhook;

$webhook = Webhook::delete("1082736198236817");

print_r($webhook);

Process Webhook events

It's easy to process events delivered to your Webhook endpoint. Remember to pass the signature header so the SDK can make sure it was StarkInfra that sent you the event.

use StarkInfra\Event;

$response = listen()  # this is the method you made to get the events posted to your webhook

$event = Event::parse($response->content, $response->headers["Digital-Signature"]);

if ($event->subscription == "pix-request.in"){
    print_r($event->log->request);
} elseif ($event->subscription == "pix-claim"){
    print_r($event->log->claim);
} elseif ($event->subscription == "pix-key"){
    print_r($event->log->key);
} elseif ($event->subscription == "pix-infraction"){
    print_r($event->log->infraction);
} elseif ($event->subscription == "pix-chargeback"){
    print_r($event->log->chargeback);
} elseif ($event->subscription == "pix-request.out"){
    print_r($event->log->request);
} elseif ($event->subscription == "pix-reversal.in"){
    print_r($event->log->reversal);
} elseif ($event->subscription == "pix-reversal.out"){
    print_r($event->log->reversal);
} elseif ($event->subscription == "issuing-card"){
    print_r($event->log->card);
} elseif ($event->subscription == "issuing-invoice"){
    print_r($event->log->invoice);
} elseif ($event->subscription == "issuing-purchase"){
    print_r($event->log->purchase);
}

Query webhook events

To search for webhooks events, run:

use StarkInfra\Event;

$events = Event::query(["after" => "2020-03-20", "isDelivered" => false]);

foreach($events as $event){
    print_r($event);
}

Get a webhook event

You can get a specific webhook event by its id.

use StarkInfra\Event;

$event = Event::get("1082736198236817");

You can also delete a specific webhook event by its id.

use StarkInfra\Event;

$event = Event::delete("1082736198236817");

print_r($event);

Set webhook events as delivered

This can be used in case you've lost events. With this function, you can manually set events retrieved from the API as "delivered" to help future event queries with "isDelivered" => false.

use StarkInfra\Event;

$event = Event::update("1298371982371929", true);

print_r($event);

Query failed webhook event delivery attempts information

You can also get information on failed webhook event delivery attempts.

use StarkInfra\Event\Attempt;

$attempts = Attempt::query(["eventIds" => $event->id, "limit" => 1]);

foreach($attempts as $attempt){
    print_r($attempt);
}

Get a failed webhook event delivery attempt information

To retrieve information on a single attempt, use the following function:

use StarkInfra\Event\Attempt;

$attempt = Attempt::get("1616161616161616");

print_r($attempt);

Handling errors

The SDK may raise one of four types of errors: InputErrors, InternalServerError, UnknownError, InvalidSignatureError

InputErrors will be raised whenever the API detects an error in your request (status code 400). If you catch such an error, you can get its elements to verify each of the individual errors that were detected in your request by the API. For example:

use StarkInfra;
use StarkInfra\Error\InputErrors;

try {
    $cards = StarkInfra\IssuingCard::create([
        new StarkInfra\IssuingCard([
            "holdeNname" => "Developers",
            "holderTaxId" => "012.345.678-90",
            "holderExternalId" => "1234",
            "rules" => [
                new StarkInfra\IssuingRule([
                    "name" => "general",
                    "interval" => "week",
                    "amount" => 50000,
                    "currencyCode" => "USD"
                ])
            ]
        ]),
    ]);
} catch (InputErrors $e) {
    foreach($e->errors as $error){
        echo "\n\ncode: " . $error->errorCode;
        echo "\nmessage: " . $error->errorMessage;
    }
}

InternalServerError will be raised if the API runs into an internal error. If you ever stumble upon this one, rest assured that the development team is already rushing in to fix the mistake and get you back up to speed.

UnknownError will be raised if a request encounters an error that is neither InputErrors nor an InternalServerError, such as connectivity problems.

InvalidSignatureError will be raised specifically by StarkInfra\Event::parse() when the provided content and signature do not check out with the Stark Infra public key.
