}Start an outbound call
Places an outbound call: the assistant must be active and needs an outbound-capable phone number (assigned to it, or passed via phone_number_id). Returns the created call immediately (status queued) — poll GET /calls/{id} or use the assistant’s webhook for the result and provider-neutral failure guidance. Destinations that are not allowed return 403 destination_forbidden. Required scope: calls:write (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, billing:write, 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.
Body
Assistant that runs the call. Must be active.
Destination in E.164 format, e.g. +4930123456.
Contact context. Custom fields follow the assistant contact-field access settings and do not fill same-named manual variables; use variables for explicit scenario inputs.
Optional explicit caller ID (one of your phone numbers). Defaults to the number assigned to the assistant.
Explicit per-call values. Strings are limited to 2000 characters; numbers and booleans become text. Values are sanitized before use. Does not edit assistant definitions or contact fields; durable retention follows the configured variable memory policy.
