DDS supports token authentication.

Token Authentication


The validity period of a token is 24 hours. If a token needs to be used, the system caches the token to avoid frequent calling.

A token specifies temporary permissions in a computer system. During API authentication using a token, the token is added to requests to get permissions for calling the API.

If you use a token for authentication, you must obtain the user's token and add X-Auth-Token to the request message header of the service API when making an API call.

When calling an API to obtain a user token, you must set auth.scope in the request body to project.

    "auth": {
        "identity": {
            "methods": [
            "password": {
                "user": {
                    "name": "username",
                    "password": "password",
                    "domain": {
                        "name": "domainname"
        "scope": {
            "project": {
               "name": "xxxxxxxx"

After a token is obtained, add 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...., add X-Auth-Token: ABCDEFJ.... in a request as follows:

Content-Type: application/json
X-Auth-Token: ABCDEFJ....
