Now we will describe the authorization code flow:

POST /oauth/oauth20/token

Returns an OAuth 2.0 token using HTTP POST.

To request an access token using this grant type, the client must have already obtained the Authorization Code from the authorization server. An Authorization Code is a short-lived token issued to the client application by the authorization server upon successful authentication/authorization of an end-user (resource owner). The client application then uses the authorization code to request an access token from the authorization server.

For detailed examples about the types of access tokens supported, with example for each type of access token, refer to OAuth: Client Authentication with the Platform’s OAuth Provider.

Note: there is a corresponding operation that performs the same action using HTTP GET: GET /oauth/oauth20/token. For information on why you might choose one or the other, see OAuth Operations: GET or POST?

Authorization Roles/Permissions: Anyone can run this operation.

Sample Request

The examples below shows token requests in an LDAP scenario, with several different grant types.

Request URL

https://{oauth-provider-url}/oauth/oauth20/token

Sample request headers

Note: In the sample request headers below, the Authorization header consist of the client’s Basic authentication header, as explained in HTTP Basic Authentication. This is one way of sending the authorization credentials. As an alternative, you can send this information in the POST body or, if you are using the GET operation, in the request parameters. For more information, see OAuth: Client Authentication with the Platform’s OAuth Provider.

POST /oauth/oauth20/token HTTP/1.1
Host: http://{oauth-provider-hostname}
Authorization: Basic czZCaGRSa3F0MzpnWDFmQmF0M2JW
Content-Type: application/x-www-form-urlencoded
Accept: application/json

Sample request body: authorization_code grant type

In the sample request body shown below, the client ID and client secret are included. When the Authorization header is included with the request message, as shown above, you don’t need to send the client ID and client secret in the parameters. Send them either in the header or in the parameters. The below is an example of sending these values in the POST request body if the Authorization header was not sent. Line breaks have been added for display purposes.
