Amazon SP-API responding with "invalid marketplaceIds provided" when patching package dimensions

[Daniell-Green]

Hello everyone!

I'm working on integrating the Amazon SP API to update item dimensions for a specific SKU. However, I'm encountering an error that states "invalid marketplaceIds provided" with no details.

I have verified that I'm passing the correct marketplace ID, but the error persists. Below is the minimal code I'm using to reproduce the issue:

from sp_api import ListingItems
from sp_api.base.marketplaces import Marketplaces
from sp_api.base import SellingApiException

class AmazonProductManager:
    def __init__(self, credentials: AmazonAuth, marketplace: Marketplaces = Marketplaces.DE):
        self.creds = credentials
        self.credentials = dict(
            refresh_token=self.creds.refresh_token,
            lwa_app_id=self.creds.lwa_app_id,
            lwa_client_secret=self.creds.lwa_client_secret,
            aws_secret_key=self.creds.aws_secret_key,
            aws_access_key=self.creds.aws_access_key,
            role_arn=self.creds.role_arn
        )
        self.marketplace = marketplace

    def update_item_dimensions(self, seller_id: str, sku: str,
                               item_dimensions: dict = None,
                               package_dimensions: dict = None):
        """Update item dimensions."""
        try:
            payload = {
                "productType": "PRODUCT",
                "requirements": "LISTING",
                "attributes": {
                    # Dimensions are added here
                }
            }

            if isinstance(item_dimensions, dict):
                if item_dimensions:
                    payload['attributes']['item_dimensions'] = item_dimensions

            if isinstance(package_dimensions, dict):
                if package_dimensions:
                    payload['attributes']['package_dimensions'] = package_dimensions

            response = ListingsItems(credentials=self.credentials,
                                     marketplace=self.marketplace).put_listings_item(
                sellerId=seller_id, sku=sku, body=payload)

            return response.payload
        except SellingApiException as e:
            print(f"Error updating item dimensions: {e}")
            return None

Details:

• I'm using Marketplaces.DE as the marketplace.
• I made sure to use valid marketplace IDs, but I'm still getting the error.
• The credentials are being passed correctly, and the API call itself is being made without any other issues.
• I tried to do the patch also without the python-sp-api library but faild getting the exact same reponse

Request_body:

{'productType': 'PRODUCT',
 'requirements': 'LISTING',
 'MarketplaceId': 'A1PA6795UKMFR9',
 'MarketplaceIds': ['A1PA6795UKMFR9'],
 'marketplaceIds': ['A1PA6795UKMFR9'],

 'attributes': {
    'package_dimensions': {
        'height': '19',
        'length': '108',
        'unit': 'CM',
        'weight': '28',
        'weight_unit': 'KG',
        'width': '67'}}
}

Response: Error updating item dimensions: [{'code': 'InvalidInput', 'message': "Invalid 'marketplaceIds' provided.", 'details': ''}]

What could be causing this error, and how can I resolve it? Any help would be greatly appreciated!

Hi @Daniell-Green, thanks for reaching out! Please note that marketplaceIds needs to be submitted in the query parameters and not in the body. In your case you have to explicitly provide marketplaceId in the put_listings_item call. Hope that helps! Thanks, Marc Selling Partner Developer Services
