Overview

This library has two modes:

1. Single-seller mode, which you should use if you only plan to make requests to the Selling Partner API with a single set of credentials (most people fall into this category, so if you're not sure, this is probably you).
2. Multi-seller mode, which makes it easy to make requests to the Selling Partner API from within Laravel when you have multiple sets of SP API credentials (for instance, if you operate multiple seller accounts, or operate one seller account in multiple regions).

Single-seller mode

Setup

1. Publish the config file:

$ php artisan vendor:publish --tag="spapi-config"

2. Add these environment variables to your .env:

SPAPI_LWA_CLIENT_ID=
SPAPI_LWA_CLIENT_SECRET=
SPAPI_LWA_REFRESH_TOKEN=

# Optional
# SPAPI_ENDPOINT_REGION=

Set SPAPI_ENDPOINT_REGION to the region code for the endpoint you want to use (EU for Europe, FE for Far East, or NA for North America). The default is North America.

Usage

SellerConnector and VendorConnector can be type-hinted, and the connector classes can be used to create instances of all APIs supported by jlevers/selling-partner-api. This example assumes you have access to the Selling Partner Insights role in your SP API app configuration (so that you can call SellingPartnerApi\Seller\SellersV1\Api::getMarketplaceParticipations()), but the same principle applies to calling any other Selling Partner API endpoint.

use Illuminate\Http\JsonResponse;
use Saloon\Exceptions\Request\RequestException;
use SellingPartnerApi\Seller\SellerConnector;

class SpApiController extends Controller
{
    public function index(SellerConnector $connector): JsonResponse
    {
        try {
            $api = $connector->sellersV1();
            $result = $api->getMarketplaceParticipations();
            return response()->json($result->json());
        } catch (RequestException $e) {
            $response = $e->getResponse();
            return response()->json($response->json(), $e->getStatus());
        }
    }
}

Multi-seller mode

Setup

1. Publish the config file:

# Publish config/spapi.php file
$ php artisan vendor:publish --provider="HighsideLabs\LaravelSpApi\SellingPartnerApiServiceProvider"

2. Change the installation_type in config/spapi.php to multi.

3. Publish the multi-seller migrations:

# Publish migrations to database/migrations/
$ php artisan vendor:publish --tag="spapi-multi-seller"

4. Run the database migrations to set up the spapi_sellers and spapi_credentials tables (corresponding to the HighsideLabs\LaravelSpApi\Models\Seller and HighsideLabs\LaravelSpApi\Models\Credentials models, respectively):

$ php artisan migrate

Usage

First you'll need to create a Seller, and some Credentials for that seller. The Seller and Credentials models work just like any other Laravel model.

use HighsideLabs\LaravelSpApi\Models\Credentials;
use HighsideLabs\LaravelSpApi\Models\Seller;

$seller = Seller::create(['name' => 'My Seller']);
$credentials = Credentials::create([
    'seller_id' => $seller->id,
    // You can find your selling partner ID/merchant ID by going to
    // https://<regional-seller-central-domain>/sw/AccountInfo/MerchantToken/step/MerchantToken
    'selling_partner_id' => '<AMAZON SELLER ID>',
    // Can be NA, EU, or FE
    'region' => 'NA',
    // The LWA client ID and client secret for the SP API application these credentials were created with
    'client_id' => 'amzn....',
    'client_secret' => 'fec9/aw....',
    // The LWA refresh token for this seller
    'refresh_token' => 'IWeB|....',
]);

Note

client_id and client_secret are nullable. If you are authorizing multiple sellers on a single SP API application, they will all use the same client ID and client secret. If you leave client_id and client_secret empty, the library will try to load those values from the SPAPI_LWA_CLIENT_ID and SPAPI_LWA_CLIENT_SECRET environment variables that are used in single-seller mode. That means that the single-seller credentials can effectively be used as master credentials in multi-seller mode.

Once you have credentials in the database, you can use them to retrieve a SellerConnector instance, from which you can get an instance of any seller API:

use HighsideLabs\LaravelSpApi\Models\Credentials;
use Illuminate\Http\JsonResponse;
use Saloon\Exceptions\Request\RequestException;

$creds = Credentials::first();
/** @var SellingPartnerApi\Seller\SellersV1\Api $api */
$api = $creds->sellerConnector()->sellersV1();

try {
    $result = $api->getMarketplaceParticipations();
    $dto = $result->dto();
} catch (RequestException $e) {
    $responseBody = $e->getResponse()->json();
}

The same goes for a VendorConnector instance:

use HighsideLabs\LaravelSpApi\Models\Credentials;
use Illuminate\Http\JsonResponse;
use Saloon\Exceptions\Request\RequestException;

$creds = Credentials::first();
/** @var SellingPartnerApi\Vendor\DirectFulfillmentShippingV1\Api $api */
$api = $creds->vendorConnector()->directFulfillmentShippingV1();

Troubleshooting

If you encounter an error like String data, right truncated: 7 ERROR: value too long for type character varying(255), it's probably because you're using Laravel's database cache, which by default has a 255-character limit on cache keys and values. This library has a migration available to fix this:

$ php artisan vendor:publish --tag="spapi-database-cache"
$ php artisan migrate
