Inventory Loader

Parameters

merchantId

Required

There is documentation on how to retrieve your merchantId in the Common required parameters section of the Flat file feeds page.

shippingGroupMap

Required if the merchant_shipping_group_name field is present in the feed file being converted.

This parameter is a mapping of your account's shipping group names to their internal Amazon identifiers.

To produce this mapping, use the getDefinitionsProductType endpoint of the Selling Partner API to retrieve your seller-account-specific product JSON schema. Make sure to use PRODUCT for the product type, the marketplace ID of the marketplace this feed will be sent to, and the same merchant ID that you're using when you submit the feed. If you're using jlevers/selling-partner-api to interact with the Selling Partner API, that would look like this:

use SellingPartnerApi\SellingPartnerApi;
use SellingPartnerApi\Enums\Endpoint;

$connector = SellingPartnerApi::seller(
    clientId: 'amzn1.application-oa2-client.asdfqwertyuiop...',
    clientSecret: 'amzn1.oa2-cs.v1.1234567890asdfghjkl...',
    refreshToken: 'Atzr|IwEBIA...',
    endpoint: Endpoint::NA,  // Or Endpoint::EU, Endpoint::FE
);
$api = $connector->productTypeDefinitionsV20200901();
$response = $api->getDefinitionsProductType(
    productType: 'PRODUCT',
    marketplaceIds: ['ATVPDKIKX0DER'],
    sellerId: 'YOUR-MERCHANT-ID',
);

Then, pass the schema URL to Converter::parseShippingGroups():

use SellingPartnerApi\FeedTransformer\Transformer;

$productTypeDefinition = $response->dto();
$schemaUrl = $productTypeDefinition->schema->link->resource;
$shippingGroupMap = Transformer::parseShippingGroups($schemaUrl);

Usage

To convert a POST_FLAT_FILE_INVLOADER_DATA feed to the newer JSON_LISTINGS_FEED format:

use SellingPartnerApi\FeedTransformer\Transformer;
use SellingPartnerApi\FeedTransformer\FeedTypes\Invloader;

$feedFile = 'path/to/your/feed.tab';
$json = Transformer::fromFile(
    Invloader::$feedType,
    $feedFile,
    'ATVPDKIKX0DER',
    [
        'merchantId' => 'A2DI..........',
        'shippingGroupMap' => $shippingGroupMap
    ]
);

$jsonFeedPath = 'path/to/new/feed.json';
file_put_contents($jsonFeedPath, json_encode($json));
