When working with the Walmart API
Data Format for Items:

The error message “INVALID_REQUEST_CONTENT” from the Walmart API indicates that there might be an issue with the request parameters. Let’s troubleshoot this together:
Check Query Parameters: Double-check the query parameters you are sending in the request payload. Ensure that they are correctly formatted and match the expected structure according to the Walmart API documentation.
Data Format: Make sure that the data you’re sending (such as the list of items) adheres to the required format. For example, when fetching item associations, the items should be represented as objects with a “sku” field, rather than plain numbers.
Headers: Verify the headers you’re including in your request. Specifically, check the following:
Here’s an example of how you might structure your request:
$url = "https://marketplace.walmartapis.com/v3/items/associations";
$ch = curl_init();
$qos = uniqid();
$fields = [
'items' => [
['sku' => '123456'],
['sku' => '778990']
]
];
$options = [
CURLOPT_URL => $url,
CURLOPT_RETURNTRANSFER => true,
CURLOPT_TIMEOUT => 60,
CURLOPT_HEADER => false,
CURLOPT_HTTPHEADER => [
"WM_SVC.NAME: Walmart Marketplace",
"WM_QOS.CORRELATION_ID: $qos",
"Authorization: Basic $authorization_key",
"WM_SEC.ACCESS_TOKEN: $token",
"Accept: application/json",
],
CURLOPT_POSTFIELDS => json_encode($fields),
];
curl_setopt_array($ch, $options);
$response = curl_exec($ch);
$code = curl_getinfo($ch, CURLINFO_HTTP_CODE);
curl_close($ch);
$response = json_decode($response, true);
Remember to replace placeholders like $authorization_key and $token with actual values. If you follow these steps and still encounter issues, consider reviewing the API documentation or reaching out to Walmart support for further assistance.
