Get Email Capabilities
GetEmailCapabilities returns a lightweight summary of email capabilities for the current tenant. Intended for non-admin users (automation builders, secret sharers) to check if external email is available without exposing provider configuration details.
Authorizations
Bearer authentication header of the form Bearer <token>, where <token> is your auth token.
This API uses OAuth2 with the Client Credential flow. Client Credentials must be sent in the BODY, not the headers. For an example of how to implement this, refer to the c1TokenSource.Token() function.
Response
Successful response
The GetEmailCapabilitiesResponse message.
True when external email addresses (outside C1 users) can be used as recipients in automation email steps. False when only the C1 built-in provider is configured (C1 users only).
