How do I integrate Intercom with WhatsApp API?
Step-by-step guide to integrating Intercom with WhatsApp Business API — which events to trigger, template categories to use, webhook architecture, and pitfalls teams miss on first rollout. Map Intercom events to Ominiflow webhooks or native connectors, submit approved templates, and route replies to a shared inbox. Pilot with Utility messages before marketing automation.

Quick answer: Intercom does not send WhatsApp messages natively. You connect it to WhatsApp Business API through a platform layer — typically webhooks or middleware — that maps Intercom events to approved templates, checks opt-in status, and logs delivery back to Intercom or your CRM. Ominiflow handles template submission, inbox handoff, and compliance guardrails so ops teams do not wire raw Graph API endpoints themselves.
Teams adopt this integration when email alerts go unread and SMS lacks context. WhatsApp gives higher open rates on the updates Intercom already knows about — new leads, payment events, task deadlines, support tickets — without asking staff to copy-paste between tools.
Why connect Intercom to WhatsApp
Most Intercom rollouts stop at email and in-app notifications. WhatsApp adds a channel your customers and internal teams already check dozens of times daily.
- Faster response on revenue events — hot leads and payment failures surface in WhatsApp within seconds of the Intercom trigger
- Richer context — buttons, PDF links, and images inside approved templates beat plain SMS
- Audit trail — delivery and read receipts finance and support leads can act on
- Agent handoff — automated first message, human takeover inside the 24-hour service window when needed
High-value Intercom → WhatsApp triggers
- User signed up — instant Utility or Marketing template with next-step CTA
- Support ticket — timed reminder sequence (T-24h / due date)
- Product tour step — status update with deep link back to Intercom
- Churn risk — escalation to assigned owner in shared inbox
Integration architecture
| Layer | Role |
|---|---|
| Intercom | Source of truth for events, records, and ownership |
| Middleware / webhook | Maps Intercom payload → template variables + opt-in check |
| Ominiflow | Template send, inbox, analytics, CRM logging |
| Meta Cloud API | Official WhatsApp delivery and quality rating |
Six-step setup (no custom app required)
- Export contacts with E.164 mobiles and documented opt-in timestamps
- Define which Intercom events warrant Utility vs Marketing templates — miscategorization causes Meta rejections
- Configure Ominiflow webhook or native connector; map fields to template variables
- Submit templates for approval; pilot with 20 records before full automation
- Route replies to shared inbox with assignment rules by territory or product
- Monitor delivery rate, block rate, and quality rating weekly for first 90 days
Template examples
- Utility: "{1} updated in Intercom. View details: {2}"
- Utility: "Reminder: {1} is due {2}. Reply HELP for assistance."
- Marketing (opt-in): "New offer for {1} — tap to view: {2}"
Implementation pitfalls
- Cold outreach — triggering Marketing templates without opt-in risks number bans
- Utility abuse — promotional copy in Utility category gets rejected or downgraded
- Zapier-only at scale — middleware delays and per-task costs add up; native connectors reduce failure points
- No reply path — one-way blasts without inbox coverage frustrate customers who reply
Metrics to track after go-live
| Metric | Healthy range | Action if off |
|---|---|---|
| Delivery rate | > 95% | Validate numbers, template category, quality rating |
| Read rate | 70–90% | Improve timing and message relevance |
| Reply rate | 10–30% (use-case dependent) | Add clear CTA; staff inbox SLA |
| Time-to-first-response | < 5 min on hot leads | Assignment rules + staffing |
