# How to Add a Follow-up in a Conversation

This guide explains how to set up a follow-up message on WhatsApp (or other channels) while staying compliant with the **24-hour conversation window** rules.

**Key sequence:** **Assign to AI agnet** → **Wait until** → **Send Message in Conversation**

* **Assign To AI agent** → Starts or re-opens the conversation window when user replies to the AI agent .
* **Wait-until** → Pauses the journey for a defined duration after the last message of the user.
* **Send Message in Conversation** → Sends the follow-up inside the active 24-hour window.

***

### Business Use Case

Suppose you want to greet a new lead with a welcome template and then follow up 10 minutes later by asking if they’d like a demo. This sequence ensures your follow-up lands at the right time and in the same conversation thread.

***

### Step 1: Create a Journey

1. Go to **Journeys** in the left menu.
2. Click **Create Journey**.
3. Enter a name (e.g., *Follow-up Journey*) and choose **Blank Journey**.

***

### Step 2: Add a Trigger

1. Add a **Trigger** (e.g., **Conversation Created**, **Contact Added to List**, or **Inbound Webhook**).
2. Select the channel (WhatsApp, Instagram, Messenger) and configure any conditions as needed.

***

### Step 3: Add the Assign to AI agent Action

1. Click the **+** button → \*\*Action → Assign to AI agent → Select the AI agent \*\*.

***

### Step 4: Add a Wait-until Step

1. After the Assign to AI Agent step, click **+** → **Action → Wait-until**.
2. Set a wait duration (e.g., **10 minutes**) or a specific time that fits your use case. Select event as **Last message is older than duration**

> Example: Wait 10 minutes after users last message to send the Follow-up.

***

### Step 5: Add the Send Message in Conversation Action

1. After the Wait step, click **+** → **Action → Send Message in Conversation**.
2. Configure the action:

   * **Conversation ID** → Select the active conversation ID (e.g., `{{conversation_id}}` or `{{inbound_webhook.inbound_webhook.conversation_id}}`).
   * **Channel** → WhatsApp (make sure the conversation window is still open).
   * **Message Type** → Text, Image, Video, Document, etc.
   * **Message Body** → Enter the follow-up message, or enable **AI Generated Follow-up Message** for a context-aware reply.

> ⚡ **Why this step?**\
> `Send Message in Conversation` delivers the follow-up inside the existing 24-hour chat, keeping context intact and ensuring compliance.

***

### Step 6: Publish and Test

1. Click **Save** → **Publish**.
2. Test the flow:
   * Trigger the journey (via webhook, conversation, or list).
   * Confirm the initial `assign to AI agent` is Triggered.
   * Wait-until for the set delay after the users message.
   * Verify the `Send Message in Conversation` arrives in the same chat.
   * Check the **Conversations tab** to confirm both messages are visible in one active conversation.

***

### Tips & Notes

* For inbound webhooks, use:
  * **Phone** → `{{inbound_webhook.inbound_webhook.phone_number}}`
  * **Conversation ID** → `{{inbound_webhook.inbound_webhook.conversation_id}}`

✅ With this setup, your chatbot can automatically send follow-ups that feel natural, land at the right time, and fully comply with platform policies.
