createShippingQuote API call returning error code 90000

Question:

Why I am getting ErrorCode 90000 as below with the createShippingQuote (Logistics API) call?

    {
      "errorId": 90000,
      "domain": "shippingPublicAPIErrorDomain",
      "subdomain": "Selling",
      "category": "APPLICATION",
      "message": "A system error has occurred.",
      "longMessage": "A system error has occurred."
    }

Answer:

Main reason could be either of the following:

• Make sure you are using the correct countryCode in the both shipTo and shipFrom address request payload
• X-EBAY-C-MARKETPLACE-ID is the required header so make sure you are using it with the correct Marketplace ID values
