Installation

This package requires Laravel 5.5 or higher.

Require the package using composer:

composer require alexvargash/laravel-stripe-plaid

The service provider will automatically get registered.

You can publish the configuration file with:

php artisan vendor:publish --provider="AlexVargash\LaravelStripePlaid\StripePlaidServiceProvider" --tag="config"

When published, the config/stripe-plaid.php config file contains:

return [

Usage

First, add the Plaid keys and environment to the config/stripe-plaid.php file or on your .env.

PLAID_ENVIRONMENT=sandbox
PLAID_SECRET=your_plaid_secret_key
PLAID_CLIENT_ID=your_plaid_client_id
PLAID_CLIENT_NAME=your_app_name

Then, you need to create the link_token which is required as a parameter when initializing Link. Once Link has been initialized, it returns a public_token.

To create the public token use createLinkToken, this function needs the $clientUserId (you can find more information here), optionally this fuction accepts $clientName, $products, $language, $countryCodes if you don't provide these values the values on config/stripe-plaid.php config file will be used.

use AlexVargash\LaravelStripePlaid\StripePlaid;

$clientUserId = 'client_user_id';

$stripePlaid = new StripePlaid();
$linkToken   = $stripePlaid->createLinkToken($clientUserId);

Now you can use the value of $linkToken on Link Web to get the public_token and account_id values.

use AlexVargash\LaravelStripePlaid\StripePlaid;

$accountId   = 'plaid_link_account_id';
$publicToken = 'plaid_link_public_token';

$stripePlaid = new StripePlaid();
$stripeToken = $stripePlaid->getStripeToken($publicToken, $accountId);

After that you can process the payment with the $stripeToken as you do with a Stripe Elements token.

The link creation and the exchange can be done with a Facade too.

use AlexVargash\LaravelStripePlaid\Facades\StripePlaid;

$clientUserId = 'your_end_user_id';

$linkToken    = StripePlaid::createLinkToken($clientUserId);

use AlexVargash\LaravelStripePlaid\Facades\StripePlaid;

$accountId   = 'plaid_link_account_id';
$publicToken = 'plaid_link_public_token';

$stripeToken = StripePlaid::getStripeToken($publicToken, $accountId);

Alternatively the Plaid keys can be set prior token exchange, this is handy when multiple Plaid accounts are going to be used.

use AlexVargash\LaravelStripePlaid\StripePlaid;

$secret      = 'your_plaid_secret_key';
$clientId    = 'your_plaid_client_id';
$environment = 'sandbox';
$accountId   = 'plaid_link_account_id';
$publicToken = 'plaid_link_public_token';

$stripeToken = StripePlaid::make($secret, $clientId, $environment)->getStripeToken($publicToken, $accountId);

Exceptions

When an error occurs a PlaidException will be thrown. You can catch the PlaidException on the Exceptions\Handler.php file:

public function render($request, Exception $exception)
{
    if ($exception instanceof \AlexVargash\LaravelStripePlaid\Exceptions\PlaidException) {
        // Manage exception here ...
    }

    return parent::render($request, $exception);
}
