Setup Guide

How to connect Zoho CRM to WhatsApp API

Install WA.Expert from Zoho Marketplace

Search for WA.Expert in the Zoho Marketplace. One-click install connects to your Zoho CRM account via OAuth.

Configure module triggers

In WA.Expert settings, select which Zoho modules trigger WhatsApp: Leads, Contacts, Deals, or custom modules. Set the trigger condition and delay.

Map phone number fields

WA.Expert maps to Zoho's Mobile, Phone, or custom phone fields. Set the priority order if multiple phone fields exist.

Create Zoho workflow actions

In Zoho CRM Workflows, add "Send WhatsApp via WA.Expert" as an action. Use Zoho merge fields to personalise the message.

Set up reply logging

Enable bidirectional sync — WhatsApp replies are logged as activities in the Zoho contact or lead record automatically.

Sample Zoho CRM → WhatsApp trigger

// Zoho CRM Workflow → WA.Expert
// Function: sendWhatsApp(lead)
phone = lead.get("Mobile");
name = lead.get("First Name");
owner = lead.get("Lead Owner");

waResponse = invokeurl[
  url: "https://api.wa.expert/v1/send"
  type: POST
  parameters: {
    "to": phone,
    "template": "lead_intro",
    "variables": {"name": name, "owner": owner}
  }
];

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

FAQ

Zoho CRM + WhatsApp — common questions

Does WA.Expert work with Zoho One?

Can I send WhatsApp from inside Zoho CRM?

Yes — WA.Expert adds a "Send WhatsApp" button to Zoho CRM lead, contact, and deal records. Sales reps can send one-off WhatsApp messages directly from Zoho without switching apps.

Are WhatsApp replies visible in Zoho?

Does this work with Zoho Bigin?
