Create a Zap to send WhatsApp Messages

Use a trigger application and an action application (Kaleyra) on the Zapier platform to create a zap to send WhatsApp messages.

You can create a zap that triggers when new information is added to the trigger application and sends a WhatsApp message to one or more customers. The first step to using Zapier WhatsApp is to create a zap and select an action. Once the action is selected and configured, you will be able to configure the WhatsApp trigger.
