generate a code using client ID in clover rest API
The client ID used in the OAuth flow is the same as the App ID found on your app's settings page in the Developer Dashboard. It and the code parameter are part of the URL when the web app is launched by the merchant from their Clover Home page.
When the merchant launches an app, they are directed to (for example) mycloverwebapp.com/?merchantid=AAAAAAAAAAAAA&employeeid=BBBBBBBBBBBBB&client_id=CCCCCCCCCCCCC&code=11111111-2222-3333-4444-555555555555
To receive an authentication token for the API, you send the client id, code, and client secret to the /oauth/token endpoint. The client secret is the App Secret found on your app's settings page.
