How to Send WhatsApp Template Messages Using a Custom Webhook with WOZTELL & Make


This tutorial explains how to send WhatsApp template messages via WOZTELL, triggered by a custom webhook in Make.  
This scenario is ideal for automating outbound WhatsApp notifications or campaigns, directly from any service that can call a webhook.


Overview


Your flow features two modules:

1. Webhooks – Custom webhook: Receives a trigger with message details and recipient phone number.
2. WOZTELL | Unleash WhatsApp – Send WhatsApp Template Message: Sends the WhatsApp template message to the specified number.

Visual flow:


Step 1: Trigger via Custom Webhook


1. In Make, add the module: Webhooks – Custom webhook.
2. Configure the webhook to receive the required data: recipient phone number and any variables for your WhatsApp template.
3. Copy and deploy your webhook URL; integrate it into your app, script, or service to trigger the flow.


Step 2: Send WhatsApp Template Message (WOZTELL)


1. Add the module: WOZTELL | Unleash WhatsApp – Send WhatsApp Template Message.
2. Connect your WOZTELL account.
3. Select the WhatsApp channel and template you want to use.
4. Map the incoming phone number and any template variables from the webhook to the corresponding fields.
5. Make sure your template is pre-approved and ready in WOZTELL.


Best Practices


- Always validate the phone number before triggering the scenario.
- Prepare your WhatsApp template with variables matching your webhook payload fields.
- Test the scenario with sample webhook calls to ensure reliable delivery.
- Monitor Make’s scenario runs for errors or failed sends.


Result


Once activated, you can programmatically send WhatsApp template messages to any number by making a simple HTTP request to your webhook—perfect for notifications, alerts, marketing, or support.


Next Steps
