Error Handling

The DeliveryTracker API runs on top of GraphQL. You should check for errors via the errors field in the Body, not the HTTP Response Status Code.

About

[Important] Errors may exist in HTTP Response Status Code 200 OK.

The Response Body containing the error contains the errors field as follows

{
  "errors": [
    {
      "message": "Error message",
      "extensions": {
        "code": "Error Code"
      }
    },
    ...
  ],
  "data": ...
}

For the values contained in errors[].extensions?.code, see ErrorCode.
