# WhatsApp Post-call Tools

> Send a WhatsApp template automatically after every call or chat ends, such as a summary, a link or the next steps.

A post-call tool runs automatically once a conversation ends, with no prompt mention needed. On a voice assistant it runs when the call completes. On a WhatsApp assistant it runs when the chat closes. Use it to follow up with a summary, a payment link or the next steps.

Only **Send WhatsApp Template** is offered post-call. By the time the conversation ends, the customer may be outside the 24-hour customer service window, and only templates are delivered outside it.

<Note>
  You need a connected WhatsApp Business account with at least one **Ready** number and one **Ready** template. See [Connect WhatsApp Business](/whatsapp/onboarding).
</Note>

## Add the tool

<Steps>
  <Step title="Open Post-call tools">
    In the agent editor, select **Tools** in the left menu, then the **Post-call** tab.
  </Step>

  <Step title="Pick WhatsApp Business">
    In the side panel select **Integration**, then **WhatsApp Business** with your account name beneath it. It shows **1 tool available**: **Send WhatsApp Template**.
  </Step>

  <Step title="Configure the message">
    | Field              | What to enter                                                                                                                                                                   |
    | ------------------ | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
    | **Send from**      | A registered number on the account.                                                                                                                                             |
    | **Send to**        | Leave blank to message the customer from the conversation: the caller's number on a voice call, or their WhatsApp number on a chat. Or set a **Variable** or **Static** number. |
    | **Template**       | An approved template.                                                                                                                                                           |
    | **Body variables** | One row per variable, each **Variable** (a custom variable of the conversation) or **Static**.                                                                                  |
  </Step>

  <Step title="Test and import">
    Use **Add test value** and **Run test** to send a real message, then select **Import**. From now on the template is sent after every conversation this assistant handles.
  </Step>

## Common set-ups

<AccordionGroup>
  <Accordion title="Follow up on WhatsApp after a voice call">
    Add the tool to a **voice** assistant's post-call tools with a Utility template such as:

    ```text theme={null}
    Hi {{1}}, thanks for speaking with us about {{2}}. Reply here if you have any
    questions and we'll pick up where we left off.
    ```

    Map `{{1}}` to the `name` custom variable and `{{2}}` to a static product name. Leave **Send to** blank so it goes to the number that was called.
  </Accordion>

  <Accordion title="Send a summary when a WhatsApp chat closes">
    Add the tool to the **WhatsApp** assistant itself. It runs when the chat closes. A customer who simply stops replying may not trigger it for several hours; see [when a chat opens and closes](/whatsapp/create-agent#when-a-chat-opens-and-closes).
  </Accordion>

  <Accordion title="Notify your team instead of the customer">
    Set **Send to** to **Static** with a team member's number, and use a template that carries the details you need in its variables.
  </Accordion>
</AccordionGroup>

## Check what was sent

Post-call sends appear as tool calls on the conversation in **Logs**, with the resolved sender, recipient, template and Meta's result. To be notified from your own systems as well, subscribe to [webhook events](/whatsapp/events).
