- `_2CHAT_LIST_WEBHOOKS` — List Webhook Subscriptions — List all configured webhook subscriptions for WhatsApp and phone call events. Use this when you need to audit, review, or retrieve UUIDs of your active webhook subscriptions. Returns details including webhook UUID, event type, channel UUID, callback URL, and creation timestamp.

## How agents use 2chat

Inside a Definable workflow, 2chat is one of the tools the **Distributor specialist** can call. Example coordination patterns:

- **Researcher → 2chat** — the Researcher (GPT-5.5) pulls context from 2chat (records, threads, documents), synthesises findings, and briefs the rest of the team.
- **Writer → Distributor → 2chat** — the Writer (Claude Opus 4.7) drafts copy in brand voice, the Verifier passes it, then the Distributor writes the result into 2chat (create record, post message, draft email).
- **Designer / Engineer → Distributor → 2chat** — the Designer ships an asset or the Engineer ships a code change, the Distributor delivers it via 2chat (attach file, open PR comment, post status).

The Verifier checks every 2chat call. On rate limit, schema drift, or auth refresh it self-heals and retries — the workflow completes without manual intervention.
