Dynamic Sandbox for Listing Products

[janhellopine]

Is it true that there is no dynamic sandbox for the Listings Items API? Is there a best practice in place to test the creation of products?

Hi @janhellopine,

We launched today a new change in the Listings API to check for validation errors while creating a listing on Amazon. Please review this announcement for more information about the validation preview: https://developer-docs.amazon.com/sp-api/changelog/update-listings-items-api-v2021-08-01-now-supports-previewing-errors

That's a game changer, thank you!

I am not sure if I can still ask here. This is indeed a nice feature. It works for me for putListingsItem, but unfortunately not for patchListingsItem. For the latter I get 429 and this response every time:

{
    "errors": [
        {
            "code": "QuotaExceeded",
            "message": "You exceeded your quota for the requested resource.",
            "details": ""
        }
    ]
}

My sample request is:

{
    "productType": "ACCESSORY_OR_PART_OR_SUPPLY",
    "patches": [
        {
            "op": "replace",
            "path": "/attributes/item_name",
            "value": [
                {
                    "language_tag": "es_ES",
                    "marketplace_id": "A1RKKUPIHCS9HS",
                    "value": "some name"
                }
            ]
        }
    ]
}

NOTE: It happens during manual tests from postman so I don't think I am exceeding limits.
