How do I generate the OAuth Access Token for an API?

To generate the OAuth Access Token, you need to:

1. Have API Application for the specific API approved and enabled
2. Have the OAuthID and Secret generated from the API application
3. Use the OAuth Server URL Prefix to generate Access Token.

Below is the Curl structure:

curl -L -X POST 'https://api.ariba.com/v2/oauth/token?grant_type=openapi_2lo' \
-H 'Authorization: Basic MzMyZDc3OTktYmRhZi00NTg2LWE5ZmYtMjU0MDZhZjQxYmY3OnJmZ2ZzVHdYanJuUnN1dlRlSWdZVlJYUm9uYxVVdy' \
-H 'Cache-Control: no-cache' \
-H 'Content-Type: application/x-www-form-urlencoded'

You can find the value of OAuth Server URL Prefix for your region on the SAP Ariba Developer Portal on the Discovery page for any API in the Environment Details table. Please login to the developer.ariba.com and choose the region where your realm resides. Each API Swagger will have a specific OAuth Server URL Prefix defined.
