Overview
This node integrates with the WAMM PRO API to send WhatsApp messages using predefined templates. It allows users to send template-based WhatsApp messages to specified phone numbers, optionally scheduling the message for a later time and customizing the template with parameters.
Common scenarios where this node is beneficial include:
- Sending automated notifications or alerts via WhatsApp using approved message templates.
- Personalizing template messages by replacing placeholders with dynamic data.
- Scheduling template messages to be sent at specific times.
For example, a business can use this node to send appointment reminders or promotional messages using WhatsApp templates, filling in customer-specific details dynamically.

Dependencies
- Requires an API key credential for authenticating with the WAMM PRO API.
- The node makes HTTP GET requests to the WAMM PRO API endpoint (
https://app.wamm.pro/api/send). - Proper configuration of the WAMM instance ID and API credentials is necessary.
Troubleshooting
- Invalid JSON format for template parameters: If the
Template Parametersproperty contains malformed JSON, the node will throw an error. Ensure the JSON string is valid. - API failures: If the WAMM API returns a failure status, it will be logged as a warning. Check that the instance ID, phone number, and template ID are correct and that the API token has sufficient permissions.
- Scheduling errors: Incorrectly formatted schedule times may cause the message not to be scheduled properly. Use the specified formats exactly.
- Network issues: Connectivity problems to the WAMM API endpoint will cause request failures.
To resolve errors, verify all inputs, ensure valid JSON in parameters, and confirm API credentials and network access.
