Setup Guide

How to connect Zapier to WhatsApp API

Create a WA.Expert account and get your API key

Search for WA.Expert in Zapier

In Zapier, create a new Zap. For the Action step, search "WA.Expert" and select "Send WhatsApp Message."

Connect your WA.Expert account

Enter your WA.Expert API key when prompted. Zapier stores this securely for all future Zaps.

Configure the trigger

Set up your trigger app (Typeform, Calendly, Shopify, etc.) with the relevant event (new submission, new booking, new order).

Map trigger data to WhatsApp fields

Map the phone number field from your trigger app to the "To" field. Map name, date, amount or any other field to your WhatsApp template variables.

Sample Zapier → WhatsApp trigger

// Zapier Action: WA.Expert — Send WhatsApp
// Trigger: Typeform — New submission
// Action config (Zapier visual mapper):

To (phone): {{22. Phone Number}}
Template: form_confirmation_v1
Variable 1 (name): {{1. What is your name?}}
Variable 2 (form): {{zap.name}}
Variable 3 (date): {{zap.timestamp}}

// Result: WhatsApp fires within seconds of submission

WA.Expert handles WhatsApp API authentication, template management, and message delivery — you only need to pass the trigger data from Zapier. No WhatsApp API knowledge required.

FAQ

Zapier + WhatsApp — common questions

Does WA.Expert have a native Zapier app?

Yes — WA.Expert is available as a Zapier app. Search "WA.Expert" in the Zapier action search. No custom webhook configuration needed.

Can I use Zapier Filters to conditionally send WhatsApp?

Yes — Zapier's Filter step lets you add conditions before the WA.Expert action. For example: only send WhatsApp if the country field equals "India" or only if the form score is above 7.

What is the difference between using Zapier vs direct WA.Expert integration?

Direct integration (e.g., Shopify plugin, HubSpot native) is faster and doesn't add Zapier task costs. Zapier is the right choice when the app you want to connect doesn't have a native WA.Expert integration, or when you want to add filters, delays, or multi-step logic without writing code.

Can Zapier receive WhatsApp replies and trigger actions?

Yes — WA.Expert can send incoming WhatsApp replies to a Zapier webhook trigger. This allows you to build two-way flows: customer replies "YES" to a WhatsApp → Zapier receives the reply → updates a Google Sheet, sends a Slack notification, or creates a HubSpot deal.

How many Zapier tasks does a WhatsApp message use?

One WhatsApp message via Zapier uses one Zapier task (the WA.Expert send action). If your Zap has multiple steps before the send, each step uses one task. Plan your Zapier task quota accordingly for high-volume use cases.

What Zapier plan do I need?

WA.Expert works with all Zapier plans including Free (100 tasks/month) and Starter. For high-volume automation, Zapier Professional or above is recommended. For cost-effective high-volume automations, consider using Pabbly Connect or Make instead of Zapier.
