Setup Guide

How to connect Intercom to WhatsApp API

Set up Intercom webhook for user events

In Intercom: Settings → Integrations → Webhooks. Add WA.Expert webhook URL. Subscribe to events: conversation_created, user_created, user_tag_created.

Use Intercom Series for WhatsApp sequences

In Intercom Series (email automation): add a "Send to Webhook" action at key points in your series. This fires WA.Expert API when an Intercom user reaches that stage — combining Intercom's segmentation with WhatsApp delivery.

Map Intercom user attributes to WhatsApp

Intercom user attributes (name, phone, plan, trial_days_remaining) are passed in the webhook payload. Map phone to WA.Expert "to" field. Map other attributes to template variables.

Collect phone numbers in Intercom

If Intercom doesn't have user phone numbers: add a phone capture moment in your product onboarding (Intercom tour or conversation) or during trial signup. Store as a custom Intercom user attribute.

Set up event-based triggers

For product usage events (feature_used, milestone_reached): use Intercom's Custom Events to trigger webhooks. When a user hits a specific product event, the webhook fires WA.Expert to send the WhatsApp.

Sample Intercom → WhatsApp configuration

// Intercom webhook → WA.Expert
// Event: user_tag_created (tag: "trial-day-12")
{
  "topic": "user_tag_created",
  "data": {
    "item": {
      "name": "Priya Sharma",
      "phone": "+919876543210",
      "custom_attributes": {
        "plan": "trial",
        "trial_days_remaining": 2,
        "flows_created": 3
      }
    }
  }
}

WA.Expert handles WhatsApp API authentication, template approval, and delivery. You pass trigger data from Intercom — no WhatsApp API expertise needed.

FAQ

Intercom + WhatsApp — common questions

Does Intercom have a native WhatsApp integration?

Intercom supports WhatsApp as an inbound channel (customers messaging you via WhatsApp, handled in the Intercom inbox). For outbound WhatsApp — sending messages to users based on Intercom events — WA.Expert via webhook is the recommended approach.

Can I use Intercom's segmentation to target WhatsApp messages?

Yes — Intercom's powerful user segmentation (by plan, usage, last seen, custom attributes) can be used to create user tags or trigger webhooks that fire WhatsApp via WA.Expert. This is more sophisticated than basic time-delay sequences.

What SaaS events work best with WhatsApp?

Top 5 SaaS events for WhatsApp: (1) Trial day 12 upgrade nudge, (2) 5-day inactive user re-engagement, (3) Feature not adopted after 7 days of account age, (4) Payment failed (subscription), (5) NPS detractor follow-up. These 5 events typically cover 80% of the SaaS WhatsApp automation value.

How do I collect phone numbers for SaaS users in Intercom?

Options: (1) Add a phone field to your signup form — most direct. (2) Intercom tour that asks for phone after day 3 with a value offer. (3) In-app prompt offering WhatsApp updates for users who opt in. (4) Checkout/payment flow that captures phone for billing notifications.

Can WhatsApp replace email in Intercom sequences for Indian SaaS?

For Indian SaaS users: WhatsApp supplements email rather than replacing it. Use email for long-form onboarding content (setup guides, tutorial videos). Use WhatsApp for high-urgency nudges (trial expiry, payment failure, critical alerts). The combination outperforms either channel alone by 2-3×.

What Intercom plan is needed for webhook integration?

Intercom webhooks are available on all paid Intercom plans. The webhook fires on user events, conversation events, and tag events. Custom Events (product usage triggers) require Intercom's Product Tours or Events add-on depending on your plan.
