Obtaining a Login Token

Function

This API is used to obtain a login token for logging in through a custom identity broker. Login tokens are issued to users to log in through custom identity brokers. Each login token contains identity and session information of a user. To log in to a cloud service console using a custom identity broker URL, call this API to obtain a login token for authentication.

The API can be called using both the global endpoint and region-specific endpoints. For IAM endpoints, see Regions and Endpoints.

By default, a login token is valid for 10 minutes. You can set a validity period from 10 minutes to 12 hours.

Request Parameters

**Table 1** Parameters in the request header
Parameter	Mandatory	Type	Description
Content-Type	Yes	String	Fill application/json;charset=utf8 in this field.

**Table 2** Parameters in the request body
Parameter	Mandatory	Type	Description
auth	Yes	Object	Authentication information.

**Table 3** auth
Parameter	Mandatory	Type	Description
securitytoken	Yes	Object	Authentication parameters.

**Table 4** auth.securitytoken
Parameter	Mandatory	Type	Description
access	Yes	String	AK.
secret	Yes	String	SK.
id	Yes	String	Temporary security token. A login token can be obtained using the security token of a custom identity broker user or a common user. For details, see Obtaining a Temporary Access Key and Security Token Through a Token. A security token can be obtained using an agency, and the session_user.name parameter must be specified in the request body. For details, see Obtaining a Temporary Access Key and Security Token Through an Agency.
duration_seconds	No	Integer	Validity period (seconds) of the login token. The value ranges from 10 minutes to 12 hours. The default value is 10 minutes, that is, 600 seconds. NOTE: If the transferred value is beyond the range (10 minutes to 12 hours), the default value 10 minutes is used. The validity period of the login token is the remaining validity period of the temporary security token or the value of duration_seconds, whichever is smaller. Set a long validity period (15 minutes to 24 hours) for the security token and ensure that the value of duration_seconds is less than the remaining validity period of the security token. If the remaining validity period of the security token is less than 10 minutes, the validity period of the login token is 10 minutes.
