Amazon SP-API: put listings product : MarketplaceId is invalid

Question

I am trying to put a product with postman to Amazon but I always get this error message:

{ "sku": "IN-192", "status": "INVALID", "submissionId": "51248ab251834af6a21a976092d3ba7f", "issues": [ { "code": "4000006", "message": "Unexpected marketplace identifier provided. Either the Amazon marketplace identifier is invalid, does not match the request parameters, or the seller is unauthorized to sell in the Amazon marketplace.", "severity": "ERROR", "categories": [] } ] }

            }
        ]
},

}

what might be the reason for this error message, I am using the correct marketplaceID and the seller has all the privileges.

Answer 1

In your payload the attribute merchant_suggested_asin has incorrect marketplace_id. Please check that for all the attributes marketplace_id shall be the same, viz.

        ...
        "merchant_suggested_asin": [
            {
                "marketplace_id": "B007KQBXN0",
                "value": "日本国"
            }
        ],
        ...

Answer 2

Looks like the payload have some issue ,Check this and build on this

{
  "offers": [{
    "marketplaceId": "*******",
    "offerType": "B2C",
    "price": {
      "amount": "2.0",
      "currency": "EUR",
      "currencyCode": "EUR"
    }
  }],
  "requirements": "LISTING_PRODUCT_ONLY",
  "attributes": {......
