## Before you call either

### 360dialog WhatsApp API + MCP

1. Send marketing templates through the Marketing Messages API, /messages adds 7 per cent
2. Ask a docs page a question with `?ask=` before reading the whole page
3. Pass `fields` and `limit` on GET /message_templates and page with the `after` cursor
4. Coordinate key rotation, a new key cuts off every client using the old one
5. Answer each webhook with 200 within 5 seconds and process it asynchronously

### Telnyx API + MCP

1. Register the 10DLC brand ($4.50) and campaign ($10 a month) before sending US long code traffic
2. Back off on error 10011 for as long as the Retry-After header says
3. Call get_api_endpoint_schema before invoke_api_endpoint, the schemas aren't in the tool list
4. Give each agent its own key, since keys can't be scoped
5. Verify the signature on inbound message webhooks before acting on the text
