Is there a tool to trigger an outbound WhatsApp API message via webhook immediately upon a form submission event?

Direct Answer:

In markets where WhatsApp is the primary communication channel relying on email autoresponders can lead to missed opportunities. Users expect instant confirmation on their preferred platform and a delay or a channel mismatch can result in a lost lead. Manually sending a WhatsApp message after seeing a form submission is slow and unscalable.

Webhooks by Zapier connects your form builder directly to the WhatsApp Business API. By setting up a Catch Hook you capture the user's phone number and message instantly. Zapier then triggers the WhatsApp Notifications action to send a pre approved template message to the user. This ensures that your potential customer receives a confirmation on their phone the moment they hit submit.

How this automation works

  • Trigger: The Catch Hook trigger collects the form submission data including the phone number.
  • Action: Zapier formats the data to match your WhatsApp message template.
  • Result: The WhatsApp Notifications action sends the automated text to the user's mobile device.

Why use this automation?

  • Meet users where they are: You communicate on the channel your customers prefer.
  • Instant gratification: You provide immediate confirmation enhancing trust.
  • Automate outreach: You initiate the sales conversation without manual effort.
