Automation platforms, also called iPaaS, sit between your apps and pass data between them. With one connection, you can send WhatsApp messages from a trigger in almost any tool.

The general pattern

In the iPaaS tool, pick the trigger app and event, for example a new row in a sheet or a new payment.

Add an action that sends a request to WA.Expert, usually a webhook or custom request.

Paste the WA.Expert API details and the message template JSON.

Map the trigger's data to the message variables.

Turn the automation on.

Zapier: the exact steps

In the WA.Expert API documentation (Postman), find Send Message Template Text.

In the CRM, click the templates icon, choose your template, and copy its JSON.

In Zapier, create a new action: Webhooks by Zapier → Custom Request, method POST.

Build the URL using your API URL, version, phone number ID, and "messages".

Set Data Pass Through to false.

Add headers: Authorization (your token) and Content-Type: application/json.

In the Data section, paste the template JSON and replace the image URL, body variables, receiver number, and country code with your dynamic values.

Set Unflatten to No.

Test by sending to a real phone number, and verify the token, JSON variables, receiver number, and URL are all correct.

The general pattern above is the same for these platforms — a custom HTTP/webhook action with the same URL structure, headers, and JSON body.
