`POST` `https://example.com/documentprocessing/document/info`

### Description

Returns information about the document and document content.

### 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](https://docs.textcontrol.com/ds-server/administration/oauth/llms-full.txt)). 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](https://docs.textcontrol.com/ds-server/administration/oauth-grant-types/llms-full.txt)).

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` |

### Request Payload

### 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 a JSON string ("The JSON value could not be converted to System.String."). 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 document was found in the body. |
| 400 | A 400 (Bad Request) is returned, if the uploaded document is not valid. |
