Integrate Wati, the WhatsApp Business platform, into the workflow. Reply to customers with text, files, buttons, and lists; send approved template messages to one contact or a broadcast list; manage contacts and their attributes; read a conversation; and hand chats to a teammate or team. Can also run workflows when a message arrives or a sent message is delivered, read, replied to, or fails. WhatsApp only allows free-form messages within 24 hours of the contact’s last message; outside that window, or to start a conversation, send an approved template. Requires your Wati API endpoint and an API token.
Agent Serve accounts are created by invitation. Request access for your team, or accept an invitation from your workspace admin, then sign in.
Open your workspace, drag a Wati block onto the workflow builder, and paste in your Wati API key.
Pick the tool you need, wire in an AI agent for reasoning or data transformation, and run. Your Wati automation is live.
12 Wati tools available in Agent Serve.
Send a free-form WhatsApp text message to a contact through Wati. ${WATI_SESSION_WINDOW_NOTE} A success means Wati accepted the message, not that it was delivered.
Send a WhatsApp-approved template message to one contact through Wati. Templates are required to start a conversation or to message a contact more than 24 hours after their last message; inside that 24-hour window a free-form session message also works. Marketing templates are subject to daily limits. A success means Wati accepted the message, not that it was delivered.
Send one WhatsApp-approved template to up to 1000 contacts in a single Wati call, each with their own placeholder values. Use templates for any contact who has not messaged you in the last 24 hours. A success means Wati queued the sends; check invalidWhatsappNumbers and the status webhooks for failures.
Send an image, video, audio file, or document to a contact on WhatsApp through Wati, from a public URL, with an optional caption. Set voice to send an OGG audio file as a voice note. ${WATI_SESSION_WINDOW_NOTE}
Send a WhatsApp interactive message through Wati: up to 3 quick-reply buttons, or a list of up to 10 options behind a menu button. The contact's choice arrives on the Wati webhook. ${WATI_SESSION_WINDOW_NOTE}
List the WhatsApp message templates in a Wati workspace with their category, approval status, and body text. Only APPROVED templates can be sent, and a template is what you need to message a contact outside the 24-hour session window.
List contacts in a Wati workspace, optionally filtered by name, creation date, or contact attribute.
Add a contact to a Wati workspace by WhatsApp number, with a name and custom attributes. Wati also adds contacts automatically on the first message, so this is mainly for saving attributes up front.
Set custom attributes on a Wati contact, such as lead stage, city, or order ID, so they can fill template placeholders and segment broadcasts.
Get the WhatsApp conversation history with one contact from Wati, newest first, optionally limited to a UTC time range. Use it to give an agent context before replying.
Assign a WhatsApp chat in the Wati team inbox to a teammate by email, for example to hand a conversation from a bot to a human. Leave the email empty to assign the chat back to the bot.
Route a WhatsApp chat in the Wati team inbox to one or more teams by name, such as Sales or Support. Available on the Wati Pro and Business plans.
