Authentication

Authentication Using Tokens

The validity period of a token is 24 hours. When using a token for authentication, cache it to prevent frequently calling the IAM API.

A token specifies certain permissions in a computer system. Authentication using a token adds the token to a request as its header during API calling to obtain permissions to operate APIs through IAM.

The API for obtaining a token is POST https://{IAM endpoint}/v3/auth/tokens. For details about how to obtain IAM endpoints, see Endpoints.

{
	"auth": {
		"identity": {
			"methods": [
				"password"
			],
			"password": {
				"user": {
					"name": "username",    //Username
					"password": "********",    //Login password
					"domain": {
						"name": "domainname"    //Name of the account that the user belongs to
					}
				}
			}
		},
		"scope": {
			"project": {
				"name": "xxxxxxxx"    //Project name
			}
		}
	}
}

After a token is obtained, the X-Auth-Token header field must be added to requests to specify the token when calling other APIs. For example, if the token is ABCDEFJ...., X-Auth-Token: ABCDEFJ.... can be added to a request as follows:

POST https://{endpoint}/v3/auth/projects
Content-Type: application/json
X-Auth-Token: ABCDEFJ....
