As an example, you can view our OAuth flow in action on Zapier. Try to connect your Cal.com account [here](https://zapier.com/apps/calcom/integrations). To enable OAuth in one of your apps, you will need a Client ID, Client Secret, Authorization URL, Access Token Request URL, and Refresh Token Request URL.

### OAuth Client Credentials

Only the Cal.com team can create new OAuth clients. Please fill out [this form](https://i.cal.com/forms/4052adda-bc79-4a8d-9f63-5bc3bead4cd3) and book us to get started.

The Cal.com team will register the app and provide you with the Client ID and Client Secret. Keep these credentials confidential and secure.

### Authorization URL

To initiate the OAuth flow, direct users to the following authorization URL:

- `https://app.cal.com/auth/oauth2/authorize`
- URL Parameters:
  - _client_id_
  - _state_: A securely generated random string to mitigate CSRF attacks
  - _redirect_uri_: This is where users will be redirected after authorization

After users click _Allow_, they will be redirected to the redirect_uri with the code (authorization code) and state as URL parameters.
