Stored Procedures
Stored procedures are function-like interfaces that extend the functionality of the adapter beyond simple SELECT/INSERT/UPDATE/DELETE operations with Trello.
Stored procedures accept a list of parameters, perform their intended function, and then return, if applicable, any relevant response data from Trello, along with an indication of whether the procedure succeeded or failed.
Trello Adapter Stored Procedures

| GetOAuthAccessToken | Gets an authentication token from Trello. |
| GetOAuthAuthorizationURL | Gets the authorization URL, which must be opened separately by the user to grant access to your application. Only needed when developing Web apps. You will request the OAuthAccessToken from this URL. |
