Hello, we are developing a fully custom booking website for IndoPsyCare using the [SimplyBook.me](http://SimplyBook.me) JSON-RPC API, without the default booking page or booking widget.
We need to implement:
1. Client sign-in with Google
2. Client sign-up with Google
3. Client sign-in with Facebook
4. Client sign-up with Facebook
We reviewed the API Explorer, API Documentation, and User API Guide but could not find methods for social client authentication.
Does the public API support exchanging a Google or Facebook OAuth token for a [SimplyBook.me](http://SimplyBook.me) client account or session?
If supported, please provide the method name, required parameters, provider values, token response, account-matching behavior, and implementation example.
If social authentication is only supported on the [SimplyBook.me](http://SimplyBook.me) booking page or widget, please confirm that it is unavailable through the public API.

Hi **[Pandi](https://tech-support.simplybook.me/u/pandi)**,
The public API doesn’t support exchanging a Google or Facebook OAuth token for a [simplybook.me](http://simplybook.me) client account or session.
The only client authentication methods currently available in the public API are:
- POST /public/clients/register — creates a new client account with email, name, password (no OAuth/social provider option)
- POST /public/clients/login — authenticates with login/password
- POST /public/clients/login-by-hash — authenticates via a hash link sent by email
- POST /public/auth/token — company/widget-level auth token (not client-level)
None of these accept a provider name, an OAuth/id\_token, or an access\_token, and there’s no account-matching logic for social identities exposed via the API.
Social sign-in with Google/Facebook is currently only available on the native [simplybook.me](http://simplybook.me) booking page/widget, not through the public API. If you need this on a custom booking site, you’d have to implement the OAuth flow yourself (verify the Google/Facebook token client-side or on your backend) and then create/log in the client via the standard register/login methods using the email address returned by the provider.
Best regards,
Vitalii
