  • OutSystems supports many media types in the Content-Type header of REST API requests. However, depending on the input parameter's data type, the following rules apply:

    Input Parameter Data Type Accepted Request Media Type
    Record, List application/json
    Basic Data Types text/<any_subtype>
    Binary any

    If you send a request with a Content-Type header that the method doesn't support, you receive a response with status code 415. Additionally, you get the following error message in the response body:

        "Errors": [
            "The request entity's media type 'text/plain' is not supported for this resource."
        "StatusCode": 415
