To integrate Aircall with Ampersand, you must register an Aircall OAuth2 application. To do this, contact marketplace@aircall.io and provide the following details:
Name and Purpose of your application.
Redirect URI for an HTTPS endpoint that will handle the secure callback. Use the following callback URL for Ampersand integration: https://api.withampersand.com/callbacks/v1/oauth.
Install URI: A valid installation URI for your application.
Once you have registered your application, you will receive two credentials: client_id and client_secret. These are required to connect Aircall with Ampersand.
