To ensure the continuity of your API calls, you must generate a new access token by using the refresh token. A new token can only be generated if the initial access token has either Expired or is within 2 minutes of its expiration.

To get the new access token:

1. Make a POST call to the same OAuth token URL you used to get the initial access token.
2. Use the following parameters in your request:
   grant_type = refresh_token
   refresh_token = {value of the refresh token from the initial token call}

Below is the cURL command structure for this call.

curl -X POST \

'https://api.ariba.com/v2/oauth/token?grant_type=refresh_token&refresh_token={refreshtokenvalue}' \
-H 'Authorization: Basic {Base64 Secret Key}' \
-H 'Content-Type: application/json' \
-H 'cache-control: no-cache'

• [refreshtokenvalue]: The value of the refresh_token you received in the initial authentication response.
• [Base64 Secret Key]: Your application's Base64 encoded OAuth secret.

Note: The URL in the example is for the US data center. If you are using a different data center, you must replace the URL accordingly.
