EDB Ark provides JSON-compatible support for the API as described in this guide. The API uses token-based authentication. You should include a valid token string in the X-Auth-Token header when calling any resource except /tokens. For information about retrieving a token, see Section 2.1.39.Please note: Template Only users are required to use the Ark version 3.0 API or later. Template Only users that attempt to use a URI with an API version that is less than 3.0 will receive an authentication error (HTTP response code 401) or a method not allowed error (HTTP response code 405) when attempting to generate a token.For detailed information about restrictions placed on Template Only users, please see the EDB Ark Getting Started Guide, available through the EDB Ark Dashboard.
