## API

- [Quick Start](https://twentytwo.documentationai.com/api-reference/quick-start.md): No description found
- [Authentication](https://twentytwo.documentationai.com/api-reference/authentication.md): No description found
- [Errors & Rate Limits](https://twentytwo.documentationai.com/api-reference/error-rate-limits.md): No description found
- [Get Call Details](https://twentytwo.documentationai.com/api-reference/get-call-details.md): Returns full details for a single call — status, duration, cost,
input parameters, output parameters, recording, and transcript.

> **Note:** Recording and transcript URLs expire 30 days after the
> call ends. Download the files before `expires_at` if you need to
> retain them permanently.

- [List Calls](https://twentytwo.documentationai.com/api-reference/list-calls.md): Returns a list of all calls made from your workspace, newest first.

- [Initiate a Call](https://twentytwo.documentationai.com/api-reference/initiate-call.md): Triggers a single outbound AI voice call to a specified phone number
using a published assistant.

This endpoint is **non-blocking** — it returns immediately once the
call is queued. Use the returned `call_id` with
[Get Call Detail](#operation/getCallDetail) to fetch results once the
call completes.

Optionally, configure automatic retries with `retry_count` and
`retry_interval_minutes`. If the call is not connected (for example,
the recipient is busy or does not answer), Twenty2 will re-attempt the
call up to `retry_count` times, waiting `retry_interval_minutes`
between each attempt.

> **Calling window:** Calls are only placed between **9:00 AM and
> 9:00 PM IST** to prevent your number from being flagged as spam.
> Calls triggered outside this window are queued and placed at
> 9:00 AM the following day. Retry attempts that fall outside the
> calling window are likewise deferred to the next 9:00 AM.


## Webhooks

- [Webhooks](https://twentytwo.documentationai.com/webhooks.md): Get notified instantly when a call completes via webhook events.
