List email sender choices
Returns the secrets-free sender choices that can be stored on a reusable send_email tool: automatic routing, workspace SMTP, platform mail, and verified SendGrid addresses. Also returns workspace display-name and signature defaults. Required scope: settings:read or assistants:read. Requires workspace owner/admin role.
Authorizations
API key (fam_..., created under Settings → API Keys) or an OAuth 2.0 access token (fam_at_...). Keys can be restricted to scopes such as assistants:read, calls:write, campaigns:write, automations:read, dashboards:read, dashboards:write, leads:write, segments:write, phone_numbers:write, sip_trunks:write, knowledge:write, voices:read, billing:read, settings:write, platform:read, platform:write; a *:write scope implies the matching *:read. Automation and dashboard endpoints also accept the legacy calls:* scope. Keys without scope restrictions have full access.
