Setup Guide

How to connect Google Forms to WhatsApp API

Enable form response collection to Sheets

In Google Forms → Responses → Link to Sheets. This creates a connected Google Sheet that receives all form submissions in real-time.

Add Google Apps Script trigger

In the linked Sheet: Extensions → Apps Script. Add an onFormSubmit() trigger that calls WA.Expert API with the respondent's phone and form answers.

Identify the phone number question

In your Apps Script, identify which column contains the phone number (from the "Phone Number" question in your Form). Pass this to WA.Expert as the "to" field.

Map form answers to WhatsApp variables

Pass relevant form answers (name, email, course selected, enquiry type) as variables in your WhatsApp template. The confirmation message can be personalised to what they submitted.

Test with a sample submission

Submit the form with your own phone number. Verify the WhatsApp confirmation arrives within 30 seconds. Check that the variables are correctly populated.

Sample Google Forms → WhatsApp configuration

// Apps Script: onFormSubmit trigger
// Fires for every Google Form submission

function onFormSubmit(e) {
  var responses = e.namedValues;
  var phone = responses["Phone Number"][0];
  var name = responses["Your Name"][0];
  var course = responses["Course Interest"][0];
  
  UrlFetchApp.fetch("https://api.wa.expert/v1/send", {
    method: "POST",
    payload: JSON.stringify({
      to: phone,
      template: "form_confirmation",
      variables: {name, course}
    })
  });
}

WA.Expert handles WhatsApp API authentication, template approval, and delivery — you only pass the trigger data from Google Forms. No WhatsApp API expertise needed on your end.

FAQ

Google Forms + WhatsApp — common questions

Does Google Forms have a direct WhatsApp integration?

Not natively. The integration is achieved via Google Apps Script (free, built into Google Workspace) or via Zapier/Pabbly/Make. Apps Script is the most popular approach for Indian users as it has no monthly cost.

Can I send WhatsApp to both the form submitter and my team?

Yes — your Apps Script or Zapier/Pabbly flow can send two WhatsApp messages: one to the respondent's phone number (confirmation) and one to your team's number (lead notification with form details).

What if the form doesn't collect phone numbers?

If your existing form doesn't have a phone field, add one. Make it optional initially and communicate that it's for WhatsApp updates. Over time, most users provide it when they understand the benefit. Alternatively, collect email and send via email for those without phone.

Can I personalise the WhatsApp based on what was submitted in the form?

Yes — if a form has a "Product Interest" dropdown with options A, B, C — your Apps Script can check the answer and select different WhatsApp templates or variables. For example, a "Course Interest" form can fire a course-specific brochure to each submitter.

How fast does the WhatsApp arrive after form submission?

With Google Apps Script: typically 5–30 seconds. With Zapier: 1–2 minutes (Zapier runs checks every 1–5 minutes on free plans). With Pabbly or Make: near-instant on webhook triggers.

Can I use Google Forms + WhatsApp for appointment booking?

Partially — you can collect preferred appointment time via Google Forms and send a WhatsApp confirmation. For true real-time slot availability and booking prevention (so two people don't book the same slot), use Calendly instead.
