List registries
Returns every registry linked to your partner account, with the workspace identifier and URL for each, and calendar.connected. Use it to reconcile your side against ours, and to find workspaces whose screening calls are held for want of a calendar.
Authentication
Partner API key sent as Authorization: Bearer cfk_.... Keys are partner-level — one key reaches every registry linked to your partner account and nothing else. CONFIRM issues and revokes them; a key is shown exactly once at creation because only its hash is stored, and revocation takes effect on the next request. Develop against the sandbox base URL with a sandbox key, where telephony is restricted to an allowlist you provide.
Response headers
The ID of this request. On an error it equals request_id in the body. If you sent an X-Request-Id, it is your value, returned unchanged. Log it, and quote it when contacting CONFIRM support.
