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 for calling the API used to obtain a user token, the request is successful.

Response Header

A response header corresponds to a request header, for example, Content-Type.

Figure Figure 1 shows the response header fields for the API that obtains a user token. The x-subject-token value 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 shows part of the response body for the API to obtain a user token. The following describes only part of the request body.
