OAuth refresh strategies - Transfer
Refresh on demand or handle failure
Before making any API call to Dwolla, query your database to get the stored refresh token, refresh authorization, update the new token pair in your database, and lastly make the call to Dwolla. This method prevents excessive calls to Dwolla and only requires you to refresh authorization when needed.
Make API call with access token; if access token is invalid, try to update it using the stored refresh token; if refresh request is successful, update the existing token pair in your database and re-attempt the initial API request. Optional: cache the access token for reuse on subsequent requests.
