In the section we provide more details about the errors and the standardisation we use

The API of Shiplemon uses standard HTTP error and status codes to communicate errors. There are multiple HTTP status codes for different types of errors:

  • 200 Ok — The request was performed successfully.

  • 400 Bad Request — The request was unacceptable, often due to missing a required parameter (for example user input error)

  • 401 Unauthorized — No valid access token provided. The access token was either missing or expired.

  • 403 Forbidden — The access token doesn't have permission to perform the request.

  • 404 Not Found — The requested resource doesn't exist.

  • 422 Unprocessable Entity — The request was malformed.

  • 500 Internal Server Error — An unexpected error occurred on our server. In most cases, such an error represents a bug or issue on our side. We automatically log such errors and fix them quickly. If anything like this persists, feel free to directly contact us at

Example validation error

The API follows this format for errors and validation issues. If you have any specific issue that you can't solve please contact our support:

    "error": {
        "code": "NOT_FOUND",
        "message": "Shipment does not exist",
        "metadata": null
