Create invoice payment link
Creates a short-lived, one-time billing link on the current platform domain. The link opens the latest payable plan invoice and falls back to billing management when no payable invoice exists. This recovery operation remains available with a valid credential when API Access is paused after a failed plan payment; authentication, role, and scope checks still apply. No payment-provider identifiers are returned. Required scope: billing:read (keys without scope restrictions have full access).
Authorizations
API key (fam_..., created under Settings → API Keys) or an OAuth 2.0 access token (fam_at_...). REST operations also require API Access for the credential's workspace. Keys can be restricted to scopes such as assistants:read, calls:write, campaigns:write, automations:read, dashboards:read, dashboards:write, leads:write, segments:write, loop:read, loop: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 within the workspace's available capabilities.
Response
Short-lived first-party billing link.
