WhatsApp API for Zapier
Use WireWeb with Zapier webhooks to send WhatsApp messages from lead forms, CRMs, spreadsheets, payment tools, booking apps, and ecommerce platforms without building a custom backend first.
Zapier setup pattern
Outbound WhatsApp Zap
- Choose a trigger app such as Typeform, HubSpot, Google Sheets, Stripe, Shopify, or Calendly.
- Add a Formatter step if the phone number needs cleanup.
- Add Webhooks by Zapier as a POST request.
- Send the request to the WireWeb message endpoint with your API key.
- Store the message ID back in the trigger app when needed.
Inbound WhatsApp Zap
- Create a Catch Hook trigger in Zapier.
- Use that hook URL as the WireWeb webhook destination.
- Filter by event type, phone number, or message text.
- Create a CRM note, Slack alert, spreadsheet row, or support ticket.
