README

Developer-friendly & type-safe PHP SDK specifically catered to leverage the Gr4vy API.

Important

This is a Beta release of our latest SDK. Please refer to the legacy PHP SDK for the latest stable build.

Summary

Gr4vy Typescript SDK

The official Gr4vy SDK for Typescript provides a convenient way to interact with the Gr4vy API from your server-side application. This SDK allows you to seamlessly integrate Gr4vy's powerful payment orchestration capabilities, including:

Creating Transactions: Initiate and process payments with various payment methods and services.
Managing Buyers: Store and manage buyer information securely.
Storing Payment Methods: Securely store and tokenize payment methods for future use.
Handling Webhooks: Easily process and respond to webhook events from Gr4vy.
And much more: Access the full suite of Gr4vy API payment features.

This SDK is designed to simplify development, reduce boilerplate code, and help you get up and running with Gr4vy quickly and efficiently. It handles authentication, request signing, and provides easy-to-use methods for most API endpoints.

Gr4vy PHP SDK (Beta)
Development

SDK Installation

The SDK relies on Composer to manage its dependencies.

To install the SDK and add it as a dependency to an existing composer.json file:

composer require "gr4vy/gr4vy-php"

SDK Example Usage

Example

declare(strict_types=1);

require 'vendor/autoload.php';

use Gr4vy;
use Gr4vy\Auth;

// Loaded the key from a file, env variable, 
// or anywhere else
$privateKey = "..."; 

$sdk = Gr4vy\SDK::builder()
    ->setId('example')
    ->setServer('sandbox')
    ->setSecuritySource(Auth::withToken($privateKey))
    ->setMerchantAccountId('default')
    ->build();

$response = $sdk->transactions->list();

if ($response->transactions !== null) {
    // handle response
}

Important

Please use ->setSecuritySource(Auth::withToken($privateKey)) where the documentation mentions ->setSecurity('<YOUR_BEARER_TOKEN_HERE>').

Bearer token generation

Alternatively, you can create a token for use with the SDK or with your own client library.

use Gr4vy\Auth;
$token = Auth::getToken($privateKey),

Note: This will only create a token once. Use Auth::withToken with our SDK to dynamically generate a token for every request.

Embed token generation

Alternatively, you can create a token for use with Embed as follows.

use Gr4vy;
use Gr4vy\Auth;

// Loaded the key from a file, env variable, 
// or anywhere else
$privateKey = "..."; 

$sdk = Gr4vy\SDK::builder()
    ->setId('example')
    ->setServer('sandbox')
    ->setSecuritySource(Auth::withToken($privateKey))
    ->setMerchantAccountId('default')
    ->build();

$response = $sdk->checkout_sessions.create();

$token = $token = Auth::getEmbedToken(
    privateKey: $privateKey,
    expiresIn: '+1 hour',
    checkoutSessionId: $response->checkoutSession->id,
);

Note: This will only create a token once. Use Auth::withToken with our SDK to dynamically generate a token for every request.

Merchant account ID selection

Depending on the key used, you might need to explicitly define a merchant account ID to use. In our API, this uses the X-GR4VY-MERCHANT-ACCOUNT-ID header. When using the SDK, you can set the merchantAccountId when initializing the SDK.

$sdk = Gr4vy\SDK::builder()
    ->setId('example')
    ->setServer('sandbox')
    ->setSecuritySource(Auth::withToken($privateKey))
    ->setMerchantAccountId('your-merchant-account-id')
    ->build();

Webhooks verification

The SDK makes it easy to verify that incoming webhooks were actually sent by Gr4vy. Once you have configured the webhook subscription with its corresponding secret, that can be verified the following way:

use Gr4vy;

// Webhook payload and headers
$payload = "your-webhook-payload";
$secret = "your-webhook-secret";
$signatureHeader = "signatures-from-header";
$timestampHeader = "timestamp-from-header";
$timestampTolerance = 300; // optional, in seconds (default: 0)

try {
    Webhooks::verifyWebhook(
        secret: $secret$,
        payload: $payload,
        signatureHeader: $signatureHeader$,
        timestampHeader: $timestampHeader,
        timestampTolerance: $timestampTolerance
    );
}
catch(Throwable $th$) {
    // handle the exception
}

Parameters

payload: The raw payload string received in the webhook request.
secret: The secret used to sign the webhook. This is provided in your Gr4vy dashboard.
signatureHeader: The X-Gr4vy-Signature header from the webhook request.
timestampHeader: The X-Gr4vy-Timestamp header from the webhook request.
timestampTolerance: (Optional) The maximum allowed difference (in seconds) between the current time and the timestamp in the webhook. Defaults to 0 (no tolerance).

Authentication

Per-Client Security Schemes

This SDK supports the following security scheme globally:

Name	Type	Scheme
`bearerAuth`	http	HTTP Bearer

To authenticate with the API the bearerAuth parameter must be set when initializing the SDK. For example:

declare(strict_types=1);

require 'vendor/autoload.php';

use Gr4vy;

$sdk = Gr4vy\SDK::builder()
    ->setSecurity(
        '<YOUR_BEARER_TOKEN_HERE>'
    )
    ->setMerchantAccountId('default')
    ->build();

$accountUpdaterJobCreate = new Gr4vy\AccountUpdaterJobCreate(
    paymentMethodIds: [
        'ef9496d8-53a5-4aad-8ca2-00eb68334389',
        'f29e886e-93cc-4714-b4a3-12b7a718e595',
    ],
);

$response = $sdk->accountUpdater->jobs->create(
    accountUpdaterJobCreate: $accountUpdaterJobCreate
);

if ($response->accountUpdaterJob !== null) {
    // handle response
}

Global Parameters

A parameter is configured globally. This parameter may be set on the SDK client instance itself during initialization. When configured as an option during SDK initialization, This global value will be used as the default on the operations that use it. When such operations are called, there is a place in each to override the global value, if needed.

For example, you can set merchant_account_id to `` at SDK initialization and then you do not have to pass the same value on calls to operations like get. But if you want to do so you may, which will locally override the global setting. See the example code below for a demonstration.

Available Globals

The following global parameter is available.

Name	Type	Description
merchantAccountId	string	The ID of the merchant account to use for this request.

Example

declare(strict_types=1);

require 'vendor/autoload.php';

use Gr4vy;

$sdk = Gr4vy\SDK::builder()
    ->setMerchantAccountId('default')
    ->setSecurity(
        '<YOUR_BEARER_TOKEN_HERE>'
    )
    ->build();



$response = $sdk->merchantAccounts->get(
    merchantAccountId: 'merchant-12345'
);

if ($response->merchantAccount !== null) {
    // handle response
}

Pagination

Some of the endpoints in this SDK support pagination. To use pagination, you make your SDK calls as usual, but the returned object will be a Generator instead of an individual response.

Working with generators is as simple as iterating over the responses in a foreach loop, and you can see an example below:

declare(strict_types=1);

require 'vendor/autoload.php';

use Gr4vy;

$sdk = Gr4vy\SDK::builder()
    ->setMerchantAccountId('default')
    ->setSecurity(
        '<YOUR_BEARER_TOKEN_HERE>'
    )
    ->build();

$request = new Gr4vy\ListBuyersRequest(
    cursor: 'ZXhhbXBsZTE',
    search: 'John',
    externalIdentifier: 'buyer-12345',
);

$responses = $sdk->buyers->list(
    request: $request
);


foreach ($responses as $response) {
    if ($response->statusCode === 200) {
        // handle response
    }
}

Retries

Some of the endpoints in this SDK support retries. If you use the SDK without any configuration, it will fall back to the default retry strategy provided by the API. However, the default retry strategy can be overridden on a per-operation basis, or across the entire SDK.

To change the default retry strategy for a single API call, simply provide an Options object built with a RetryConfig object to the call:

declare(strict_types=1);

require 'vendor/autoload.php';

use Gr4vy;
use Gr4vy\Utils\Retry;

$sdk = Gr4vy\SDK::builder()
    ->setMerchantAccountId('default')
    ->setSecurity(
        '<YOUR_BEARER_TOKEN_HERE>'
    )
    ->build();

$request = new Gr4vy\ListBuyersRequest(
    cursor: 'ZXhhbXBsZTE',
    search: 'John',
    externalIdentifier: 'buyer-12345',
);

$responses = $sdk->buyers->list(
    request: $request,
    options: Utils\Options->builder()->setRetryConfig(
        new Retry\RetryConfigBackoff(
            initialInterval: 1,
            maxInterval:     50,
            exponent:        1.1,
            maxElapsedTime:  100,
            retryConnectionErrors: false,
        ))->build()
);


foreach ($responses as $response) {
    if ($response->statusCode === 200) {
        // handle response
    }
}

If you'd like to override the default retry strategy for all operations that support retries, you can pass a RetryConfig object to the SDKBuilder->setRetryConfig function when initializing the SDK:

declare(strict_types=1);

require 'vendor/autoload.php';

use Gr4vy;
use Gr4vy\Utils\Retry;

$sdk = Gr4vy\SDK::builder()
    ->setRetryConfig(
        new Retry\RetryConfigBackoff(
            initialInterval: 1,
            maxInterval:     50,
            exponent:        1.1,
            maxElapsedTime:  100,
            retryConnectionErrors: false,
        )
  )
    ->setMerchantAccountId('default')
    ->setSecurity(
        '<YOUR_BEARER_TOKEN_HERE>'
    )
    ->build();

$request = new Gr4vy\ListBuyersRequest(
    cursor: 'ZXhhbXBsZTE',
    search: 'John',
    externalIdentifier: 'buyer-12345',
);

$responses = $sdk->buyers->list(
    request: $request
);


foreach ($responses as $response) {
    if ($response->statusCode === 200) {
        // handle response
    }
}

Error Handling

Handling errors in this SDK should largely match your expectations. All operations return a response object or throw an exception.

By default an API error will raise a errors\APIException exception, which has the following properties:

Property	Type	Description
`$message`	string	The error message
`$statusCode`	int	The HTTP status code
`$rawResponse`	?\Psr\Http\Message\ResponseInterface	The raw HTTP response
`$body`	string	The response content

When custom error responses are specified for an operation, the SDK may also throw their associated exception. You can refer to respective Errors tables in SDK docs for more details on possible exception types for each operation. For example, the create method throws the following exceptions:

Error Type	Status Code	Content Type
errors\Error400	400	application/json
errors\Error401	401	application/json
errors\Error403	403	application/json
errors\Error404	404	application/json
errors\Error405	405	application/json
errors\Error409	409	application/json
errors\HTTPValidationError	422	application/json
errors\Error425	425	application/json
errors\Error429	429	application/json
errors\Error500	500	application/json
errors\Error502	502	application/json
errors\Error504	504	application/json
errors\APIException	4XX, 5XX	/

Example

declare(strict_types=1);

require 'vendor/autoload.php';

use Gr4vy;
use Gr4vy\errors;

$sdk = Gr4vy\SDK::builder()
    ->setMerchantAccountId('default')
    ->setSecurity(
        '<YOUR_BEARER_TOKEN_HERE>'
    )
    ->build();

try {
    $accountUpdaterJobCreate = new Gr4vy\AccountUpdaterJobCreate(
        paymentMethodIds: [
            'ef9496d8-53a5-4aad-8ca2-00eb68334389',
            'f29e886e-93cc-4714-b4a3-12b7a718e595',
        ],
    );

    $response = $sdk->accountUpdater->jobs->create(
        accountUpdaterJobCreate: $accountUpdaterJobCreate
    );

    if ($response->accountUpdaterJob !== null) {
        // handle response
    }
} catch (errors\Error400Throwable $e) {
    // handle $e->$container data
    throw $e;
} catch (errors\Error401Throwable $e) {
    // handle $e->$container data
    throw $e;
} catch (errors\Error403Throwable $e) {
    // handle $e->$container data
    throw $e;
} catch (errors\Error404Throwable $e) {
    // handle $e->$container data
    throw $e;
} catch (errors\Error405Throwable $e) {
    // handle $e->$container data
    throw $e;
} catch (errors\Error409Throwable $e) {
    // handle $e->$container data
    throw $e;
} catch (errors\HTTPValidationErrorThrowable $e) {
    // handle $e->$container data
    throw $e;
} catch (errors\Error425Throwable $e) {
    // handle $e->$container data
    throw $e;
} catch (errors\Error429Throwable $e) {
    // handle $e->$container data
    throw $e;
} catch (errors\Error500Throwable $e) {
    // handle $e->$container data
    throw $e;
} catch (errors\Error502Throwable $e) {
    // handle $e->$container data
    throw $e;
} catch (errors\Error504Throwable $e) {
    // handle $e->$container data
    throw $e;
} catch (errors\APIException $e) {
    // handle default exception
    throw $e;
}

Server Selection

Select Server by Name

You can override the default server globally using the setServer(string $serverName) builder method when initializing the SDK client instance. The selected server will then be used as the default on the operations that use it. This table lists the names associated with the available servers:

Name	Server	Variables	Description
`production`	`https://api.{id}.gr4vy.app`	`id`
`sandbox`	`https://api.sandbox.{id}.gr4vy.app`	`id`

If the selected server has variables, you may override its default values using the associated builder method(s):

Variable	BuilderMethod	Default	Description
`id`	`setId(string id)`	`"example"`	The subdomain for your Gr4vy instance.

Example

declare(strict_types=1);

require 'vendor/autoload.php';

use Gr4vy;

$sdk = Gr4vy\SDK::builder()
    ->setServer('sandbox')
    ->setId('<id>')
    ->setMerchantAccountId('default')
    ->setSecurity(
        '<YOUR_BEARER_TOKEN_HERE>'
    )
    ->build();

$accountUpdaterJobCreate = new Gr4vy\AccountUpdaterJobCreate(
    paymentMethodIds: [
        'ef9496d8-53a5-4aad-8ca2-00eb68334389',
        'f29e886e-93cc-4714-b4a3-12b7a718e595',
    ],
);

$response = $sdk->accountUpdater->jobs->create(
    accountUpdaterJobCreate: $accountUpdaterJobCreate
);

if ($response->accountUpdaterJob !== null) {
    // handle response
}

Override Server URL Per-Client

The default server can also be overridden globally using the setServerUrl(string $serverUrl) builder method when initializing the SDK client instance. For example:

declare(strict_types=1);

require 'vendor/autoload.php';

use Gr4vy;

$sdk = Gr4vy\SDK::builder()
    ->setServerURL('https://api.example.gr4vy.app')
    ->setMerchantAccountId('default')
    ->setSecurity(
        '<YOUR_BEARER_TOKEN_HERE>'
    )
    ->build();

$accountUpdaterJobCreate = new Gr4vy\AccountUpdaterJobCreate(
    paymentMethodIds: [
        'ef9496d8-53a5-4aad-8ca2-00eb68334389',
        'f29e886e-93cc-4714-b4a3-12b7a718e595',
    ],
);

$response = $sdk->accountUpdater->jobs->create(
    accountUpdaterJobCreate: $accountUpdaterJobCreate
);

if ($response->accountUpdaterJob !== null) {
    // handle response
}

Development

Testing

To run the tests, install PHP and compose, ensure to download the private_key.pem for the test environment, and run the following.

composer install
composer test

Additionally, the following tools can be used to lint the code.

# autoformat the code
vendor/bin/pint tests src --repair 
# static code analysis
vendor/bin/phpstan analyse src tests --level 7 --memory-limit 1G --no-progress --error-format=table

Maturity

This SDK is in beta, and there may be breaking changes between versions without a major version update. Therefore, we recommend pinning usage to a specific package version. This way, you can install the same version each time without breaking changes unless you are intentionally looking for the latest version.

Contributions

While we value open-source contributions to this SDK, this library is generated programmatically. Any manual changes added to internal files will be overwritten on the next generation. We look forward to hearing your feedback. Feel free to open a PR or an issue with a proof of concept and we'll do our best to include it in a future release.
