Your server returns a TwiML document in response to a Twilio webhook POST, and Twilio executes it.\n\n```\nCaller → Twilio → POST to your webhook → Your server returns TwiML → Twilio executes it\n```\n\n---\n\n## Prerequisites\n\n- Twilio account with a voice-capable phone number\n  — New to Twilio? See `twilio-account-setup`\n- Webhook endpoint returning TwiML with `Content-Type: text\u002Fxml`\n- SDK (for programmatic generation): `pip install twilio` \u002F `npm install twilio`\n\n---\n\n## Quickstart\n\nA minimal inbound call handler that greets the caller and presents a menu:\n\n**Python (Flask)**\n```python\nfrom flask import Flask, request\nfrom twilio.twiml.voice_response import VoiceResponse\n\napp = Flask(__name__)\n\n@app.route(\"\u002Fvoice\", methods=[\"POST\"])\ndef handle_call():\n    response = VoiceResponse()\n    gather = response.gather(num_digits=1, action=\"\u002Fmenu-choice\")\n    gather.say(\"Welcome to Acme.

URL must be publicly accessible.\n\n### Dial — Connect to another number\n\n**Python**\n```python\nfrom twilio.twiml.voice_response import Dial\n\nresponse = VoiceResponse()\ndial = Dial(action=\"\u002Fdial-complete\")\ndial.number(\"+15558675310\")\nresponse.append(dial)\n```\n\n**Node.js**\n```node\nconst dial = response.dial({ action: \"\u002Fdial-complete\" });\ndial.number(\"+15558675310\");\n```\n\n### Record — Capture caller audio\n\n**Python**\n```python\nresponse = VoiceResponse()\nresponse.say(\"Leave a message after the beep.\")\nresponse.record(\n    action=\"\u002Frecording-complete\",\n    max_length=60,\n    transcribe=True,\n    transcribe_callback=\"\u002Ftranscription-ready\"\n)\n```\n\n**Node.js**\n```node\nconst response = new VoiceResponse();\nresponse.say(\"Leave a message after the beep.\");\nresponse.record({\n    action: \"\u002Frecording-complete\",\n    maxLength: 60,\n    transcribe: true,\n    transcribeCallback: \"\u002Ftranscription-ready\",\n});\n```\n\n### Voicemail — Record a message when no one answers\n\nUse `\u003CDial>` with `action` URL + `\u003CRecord>` in the action handler. When the dial times out or the callee is busy, the action URL serves TwiML with `\u003CRecord>`.\n\n**Python**\n```python\n# Primary TwiML — try to connect the call\nresponse = VoiceResponse()\ndial = Dial(action=\"\u002Fvoicemail\", timeout=20)  # 20 seconds before voicemail\ndial.number(\"+15558675310\")\nresponse.append(dial)\n\n# \u002Fvoicemail handler — plays if no answer\ndef voicemail_handler(request):\n    response = VoiceResponse()\n    response.say(\"We missed your call.

Goodbye.\");\n    res.type(\"text\u002Fxml\").send(response.toString());\n});\n```\n\n**Important:** `\u003CRecord>` captures the caller only (voicemail-style). It is NOT for recording two-party calls — see `twilio-call-recordings` for that.\n\n### Conference — Multi-party calls\n\n**Python**\n```python\nresponse = VoiceResponse()\ndial = response.dial()\ndial.conference(\n    \"Daily Standup\",\n    start_conference_on_enter=True,\n    end_conference_on_exit=True\n)\n```\n\n**Node.js**\n```node\nconst response = new VoiceResponse();\nconst dial = response.dial();\ndial.conference(\"Daily Standup\", {\n    startConferenceOnEnter: true,\n    endConferenceOnExit: true,\n});\n```\n\n### Pay — PCI-compliant payment collection\n\n> **Critical warnings:**\n> - Pay Connectors are **Console-only** — there is no REST API to create or manage connectors. Set up in Console > Voice > Pay Connectors before coding.\n> - **PCI Mode is IRREVERSIBLE** once enabled on an account. Use a dedicated sub-account for payment calls.\n\n**Python**\n```python\nresponse = VoiceResponse()\nresponse.say(\"We'll now collect your payment.\")\npay = Pay(\n    payment_connector=\"stripe_connector\",  # Name from Console setup\n    charge_amount=\"49.99\",\n    currency=\"usd\",\n    action=\"\u002Fpayment-complete\",\n    status_callback=\"\u002Fpayment-status\"\n)\nresponse.append(pay)\n```\n\n**Node.js**\n```node\nconst response = new VoiceResponse();\nresponse.say(\"We'll now collect your payment.\");\nresponse.pay({\n    paymentConnector: \"stripe_connector\",\n    chargeAmount: \"49.99\",\n    currency: \"usd\",\n    action: \"\u002Fpayment-complete\",\n    statusCallback: \"\u002Fpayment-status\",\n});\n```\n\nSupported processors: Stripe, Braintree, CardConnect. Card data routes directly to the processor — never touches your server.\n\n---\n\n## Production Deployment\n\n### Webhook Hosting\n\nFor production, do NOT use ngrok. Deploy your TwiML server with HTTPS:\n\n- **Requirement**: Public HTTPS URL, responds within 15 seconds, returns `Content-Type: text\u002Fxml`\n- **Options**: Cloud Run, AWS Lambda + API Gateway, Railway, Render — any service with TLS and auto-scaling\n- **Fallback URL**: Configure in Console (Phone Numbers > Active Numbers > select number) for when your primary server is unreachable\n\n### State Between TwiML Requests\n\nEach webhook request is stateless. To maintain conversation state across interactions:\n\n- **URL query params**: Pass state in `action` URLs — `\u002Fnext-step?language=es&dept=sales`\n- **Session store**: Use Redis or a database keyed by `CallSid`\n- **Do NOT use in-memory state** — your server may scale to multiple instances\n\n### Monitoring\n\n- **Status callbacks**: Track call lifecycle events (`statusCallback` on the call or number config)\n- **Voice Insights**: Automatic quality metrics per call (Console > Monitor > Insights)\n- **Debugger**: Console > Monitor > Errors for TwiML parsing failures and webhook timeouts\n- **Fallback URLs**: Always configure a fallback TwiML URL — serves a graceful message if your primary endpoint fails\n\n---\n\n## Webhook Request Parameters\n\n| Parameter | Description |\n|-----------|-------------|\n| `CallSid` | Unique call identifier |\n| `From` | Caller's number |\n| `To` | Called number |\n| `CallStatus` | Current status |\n| `Direction` | `inbound` or `outbound-api` |\n\n---\n\n## CANNOT\n\n- **Cannot return TwiML without correct content type** — Must use `Content-Type: text\u002Fxml`\n- **Cannot exceed 15-second webhook response time** — Twilio times out and falls back\n- **Cannot exceed 4,096 characters in `\u003CSay>` verb** — Split longer text across multiple `\u003CSay>` elements\n- **Cannot create Pay Connectors via API** — Pay Connectors are Console-only (Console > Voice > Pay Connectors). No REST API exists for connector management.\n- **Cannot reverse PCI Mode** — Once enabled on an account, PCI Mode is permanent and account-wide. Use a dedicated sub-account for payment calls.\n- **Cannot use `\u003CRecord>` for two-party call recording** — `\u003CRecord>` captures the caller only (voicemail-style). For dual-channel recording of both parties, use `record=True` on `calls.create()` or the Recordings API.\n\n---\n\n## Next Steps\n\n- **Place outbound calls (AMD, conferencing):** `twilio-voice-outbound-calls`\n- **AI voice agents with real-time speech\u002FLLM:** `twilio-voice-conversation-relay`\n","## Overview\n\nTwiML is XML that Twilio executes during a call.
