Authorization

This endpoint supports the OAuth authorization method. DS Server checks the access token only when OAuth is enabled in the admin portal (see Enable OAuth). With OAuth disabled, the default of a new installation, the endpoint accepts requests without a token.

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

Authorization Code
Client Credentials

To use the Client Credentials flow, switch on Allow “Client Credentials” grant type in the security profile (see OAuth Grant Types).

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

Authorization Header

Header field	Description
Authorization	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
access_token	The access token is passed directly in the endpoint URL as a query string. For example: `?access_token=4796E23054E64BC773CACBCAF24AD179DE9A3`

Cookie

Cookie	Description
access_token	The access token is passed in a cookie named `access_token`. For example: `Cookie: access_token=4796E23054E64BC773CACBCAF24AD179DE9A3`

Success Response

Status	Description
200	On success, the HTTP status code in the response header is 200 (OK). The response body contains the resulting document encoded as a Base64 encoded string.

Error Response

Status	Description
401	A 401 (Unauthorized) with an empty body is returned, if OAuth is enabled and the request has no valid access token.
400	A 400 (Bad Request) is returned, if the body can't be read as an AppendBody object. The body is a problem details object (`application/json`) with the title "One or more validation errors occurred." and the message per field in `errors`. This check comes before the license check.
415	A 415 (Unsupported Media Type) is returned, if the `Content-Type` header of a request with a body is not `application/json`.
405	A 405 (Method Not Allowed) with an empty body and the header `Allow: POST` is returned for any other HTTP method, for example `GET`.
400	A 400 (Bad Request) is returned, if DS Server is not licensed or the license is invalid. On a server that is not registered, the body is the JSON string `"DS Server is not registered."` (`application/json`). DS Server checks the license before the parameter values, but after it has read the body and the typed query parameters.
400	A 400 (Bad Request) is returned, if no data is found in the AppendBody object.
400	A 400 (Bad Request) is returned, if no documents were found in the AppendBody object.
400	A 400 (Bad Request) is returned, if the uploaded document is not valid.
