API Introduction
The CallMangal API lets you trigger calls against a published voice agent, in addition to the visual builder and dashboard.
This reference is generated directly from CallMangal's own OpenAPI specification (see tools/generate-api-docs.mjs) and only publishes the endpoint group verified to use customer-facing API-key authentication (X-API-Key) — every other endpoint group in the underlying spec uses session-based authentication for the logged-in web app, not a documented customer-integration mechanism, and is deliberately excluded here.
Incremental reference
Only the Voice Agents "initiate a call" endpoints are published so far. Campaigns, Telephony configuration, Webhooks, Knowledge Base and Billing are not customer-API-key authenticated in the current implementation and are not documented here — an undocumented endpoint means it isn't verified as public API surface yet, not that it doesn't exist.
