# Getting started ## What you'll build By the end of this guide, your agent answers WhatsApp text messages and voice notes on your business number, and you have sent one API-initiated template message. Expect about 20 minutes, plus a short wait for Meta to approve your first template. ## Before you start You need: - An [ElevenLabs agent](/guides/elevenagents-quickstart). Any existing agent works. - A [Meta business portfolio](https://business.facebook.com/) you can administer. - A phone number that is **not** currently used in the WhatsApp Business app or registered with another WhatsApp provider. Numbers in use elsewhere cannot be imported — see [Limitations](/guides/elevenagents-whatsapp#limitations). - A payment method in [WhatsApp Manager](https://business.facebook.com/latest/whatsapp_manager/) if you plan to send templates or make calls. Meta bills these separately from ElevenLabs. #### Import your WhatsApp business account Go to the [WhatsApp page](https://elevenlabs.io/app/agents/whatsapp) and click the _**Import account**_ button. This opens Meta's authorization flow, where you select (or create) the WhatsApp business account and phone number and grant ElevenLabs permission to manage it: WhatsApp authorization flow #### Assign your agent and choose behaviors After the import you land on the account settings page. Assign an agent — until you do, inbound messages are ignored and inbound calls are rejected: WhatsApp account page Configure how the agent behaves on this number (see [account settings](/guides/elevenagents-whatsapp#account-settings) for the full reference): - **Enable messaging** — whether the agent responds to messages at all. Turn it off if another system handles messages and ElevenLabs should only handle calls. - **Enable audio message response** — when on, the agent answers voice notes with voice notes in its own voice; when off, it always replies with text. - **Enable typing indicator** — when on, the agent marks incoming messages as read and shows a typing indicator while it works. #### Have your first conversation Message your business number from a personal phone. The agent replies. Send a voice note — it is transcribed for the agent, and the agent responds with a voice note of its own: WhatsApp text conversation The conversation appears in your [conversation history](https://elevenlabs.io/app/agents/history) as it happens. :::callout{intent="info"} A message conversation ends when the agent uses the _**End conversation**_ system tool, the _**Max conversation duration**_ elapses, or the default 15-minute inactivity timeout passes after the agent's most recent response. The next message from the user starts a new conversation. Learn more about [conversation timeouts](/guides/elevenagents-customization-conversation-flow#maximum-conversation-duration). ::: #### Send your first outbound message Reaching a user first requires a Meta-approved **message template** — WhatsApp only allows free-form business messages inside an active conversation. Create a simple Utility template in [WhatsApp Manager](https://business.facebook.com/latest/whatsapp_manager/message_templates), for example: ```text Hi {{name}}, thanks for signing up. Reply here if you have any questions. ``` Once the template is approved, send it: #### Python ```python from elevenlabs import ElevenLabs elevenlabs = ElevenLabs() elevenlabs.conversational_ai.whatsapp.outbound_message( whatsapp_phone_number_id="524029457612345", whatsapp_user_id="12213231492", template_name="welcome", template_language_code="en", template_params=[ { "type": "body", "parameters": [ {"type": "text", "parameter_name": "name", "text": "Daniele"} ], } ], agent_id="agent_9201kwcrbq9qfxaa2t8nnnkqf2w9", ) ``` #### TypeScript ```typescript import { ElevenLabsClient } from "@elevenlabs/elevenlabs-js"; const elevenlabs = new ElevenLabsClient(); await elevenlabs.conversationalAi.whatsapp.outboundMessage({ whatsappPhoneNumberId: "524029457612345", whatsappUserId: "12213231492", templateName: "welcome", templateLanguageCode: "en", templateParams: [ { type: "body", parameters: [{ type: "text", parameterName: "name", text: "Daniele" }], }, ], agentId: "agent_9201kwcrbq9qfxaa2t8nnnkqf2w9", }); ``` #### cURL ```bash curl -X POST https://api.elevenlabs.io/v1/convai/whatsapp/outbound-message \ -H "xi-api-key: $ELEVENLABS_API_KEY" \ -H "Content-Type: application/json" \ -d '{ "whatsapp_phone_number_id": "524029457612345", "whatsapp_user_id": "12213231492", "template_name": "welcome", "template_language_code": "en", "template_params": [ { "type": "body", "parameters": [ {"type": "text", "parameter_name": "name", "text": "Daniele"} ] } ], "agent_id": "agent_9201kwcrbq9qfxaa2t8nnnkqf2w9" }' ``` Two details matter here: - `template_params` is a list of component objects — the `{"type": "body", ...}` wrapper is required. - `whatsapp_user_id` is digits only, with country code and no `+` (for example `14155552671`). Find your `whatsapp_phone_number_id` on the [WhatsApp page](https://elevenlabs.io/app/agents/whatsapp) via the account menu's _**Copy phone number ID**_ option. Your phone receives the template. Reply to it — the agent picks up the conversation from there. ## If something didn't work - **The agent never replies**: no agent is assigned to the number, or **Enable messaging** is off. If those look right, check whether the agent requires [dynamic variables](/guides/elevenagents-customization-personalization-dynamic-variables) — an inbound WhatsApp conversation starts with no user-provided values, so an agent whose tools or first message require one fails before replying unless a conversation initiation webhook supplies it. See [initialization context](/guides/elevenagents-whatsapp#initialization-context). - **The import fails**: the number is already registered with another provider or the WhatsApp Business app. - **The API returned 200 but no message arrived**: the template is not approved yet, the parameters don't match the template, or your WhatsApp business account has unsettled payments (Meta error 131042). - **The user's reply started a separate conversation without context**: the recipient ID format was off — see [recipient number format](/guides/elevenagents-whatsapp-outbound#recipient-number-format). For everything else, see [Troubleshooting & FAQ](/guides/elevenagents-whatsapp-troubleshooting). ## Next steps - Personalize conversations with [dynamic variables](/guides/elevenagents-whatsapp-outbound#dynamic-variables-branches-and-environments) and the [personalization system variables](/guides/elevenagents-whatsapp#personalization). - Run outreach at scale with [outbound messages & templates](/guides/elevenagents-whatsapp-outbound). - Let the agent offer tappable choices with [interactive messages](/guides/elevenagents-whatsapp-interactive-messages). - Send WhatsApp messages from agents on other channels with [WhatsApp tools](/guides/elevenagents-whatsapp-tools). - Understand costs in the [pricing FAQ](/guides/elevenagents-whatsapp-troubleshooting#faq). ## Related pages - [Administration](./administration-index.md) - [API reference](./api-reference-index.md) - [Changelog](./changelog-index.md) - [ElevenAgents](./elevenagents-index.md) - [ElevenAPI](./elevenapi-index.md) - [ElevenCreative](./elevencreative-index.md) - [ElevenLabs Documentation Docs](../index.md) - [General Troubleshooting FAQ](./troubleshooting-index.md) - [General Website FAQ](./website-index.md) - [Help Center](./help-center-2-index.md) # Agent Instructions Cite this page’s canonical URL and keep its documentation version.
