Returned Values
Status Code
After sending a request, you will receive a response, including the status code, response header, and response body.
A status code is a group of digits ranging from 1xx to 5xx. It indicates the status of a response. For more information, see Status Codes.
For example, if status code 201 is returned after calling the Obtaining a User Token API, the request is successful.
Response Header
A response header corresponds to a request header, for example, Content-Type.
Figure 1 shows the request header fields returned after calling the Obtaining a User Token API. x-subject-token is the desired user token. You can use the token to authenticate other API calls.
Response Body
A response body is generally returned in a structured format, corresponding to the Content-Type in the response header, and is used to transfer content other than the response header.
The following is part of the response body for the Obtaining a User Token API. The following describes only part of the request body.
