This endpoint supports the OAuth authorization method:


DS Server implements OAuth as the authorization method. Two flows are supported:

  • Authorization Code
  • Client Credentials

In order to use the Client Credentials flow, this method must be explicitly enabled in the admin portal of DS Server.

In both cases, a valid access token returned from the OAuth endpoints must be passed in a Bearer Authorization Header or as a Query Parameter.

Authorization Header

Header Field Description

A Bearer authorization header (also called token authentication) contains the OAuth access token. The authorization method and a space i.e. "Bearer " is then put before your valid access token. For example:

Authorization: Bearer 4796E23054E64BC773CACBCAF24AD179DE9A3

Query Parameter

Query Parameter Description

The access token is passed directly in the endpoint URL as a query string. For example:
