Track every WhatsApp lead from Twilio back to the ad that earned it.

Twilio gives you the WhatsApp number, the API and the message delivery. WAct adds the missing layer for paid acquisition: every conversation that starts on a Twilio number is matched back to the ad click that triggered it, then exported to Meta, Google, TikTok, LinkedIn or Microsoft Ads as a real conversion event — not a clickthrough.

How the integration works

1. Connect your Twilio Account SID + Auth Token in WAct
2. Verify the WhatsApp number you want to track
3. Drop the WAct snippet on your site (Webflow, WordPress, custom — all work)
4. Map WAct conversion events to Meta CAPI, Google Ads, TikTok Events API, LinkedIn or Microsoft Ads
5. Watch attributed Twilio conversations flow into your ad platform within 10 minutes — no developer required

How it works with Twilio

When a user clicks one of your ads, a unique identifier such as fbclid, gclid, msclkid, ttclid or li_fat_id is attached to the visit. WAct securely captures the click ID and any utm_* parameters as soon as the user lands on your site.

If the same user opens WhatsApp through your Twilio link, WAct subscribes to the Twilio webhook server-side, reads the conversation start, and matches it to the original click using the stored parameters and session signals.

Once matched, the conversion event is automatically uploaded back to your ad account through the relevant API. No manual imports. No spreadsheets. No Pixel changes on your WhatsApp button.

What gets sent back from Twilio

WAct can upload verified WhatsApp conversion events from Twilio, including:

• Attributed chat start (fbclid / gclid / msclkid / ttclid / li_fat_id matched)
• Qualified lead event (conversation passes your custom rules)
• All utm_* parameters preserved end-to-end
• Twilio-side metadata: MessageSid, AccountSid, WaId (hashed), timestamps
• Custom conversion events triggered by Twilio webhook payload
• Campaign / ad set / creative-level attribution

This ensures Smart Bidding, Advantage+ and TikTok Smart Performance optimise for actual customer conversations on your existing Twilio number — not just traffic.

What gets sent back to Google

WAct can upload verified WhatsApp conversion events, including:

• Attributed chat start
• Qualified lead event
• Custom conversion events
• Campaign and keyword-level attribution

This ensures your Smart Bidding strategies optimise for actual customer conversations — not just traffic.

About Twilio

Founded in 2008 in San Francisco, Twilio is one of the most widely deployed communication APIs in the world — used by more than 300,000 customers, including a third of the Fortune 500. Twilio holds Meta's top "Tier 1" WhatsApp Business Solution Provider status and powers WhatsApp messaging for some of the largest performance marketing accounts on the platform.

Most growth teams already have a Twilio number live for transactional messaging, support flows or two-way notifications. WAct plugs into the same number — no migration, no new sender ID — and adds the missing piece for paid acquisition: closed-loop attribution from ad click to WhatsApp conversation to ad-platform conversion event.

What WAct + Twilio unlocks

Click-level attribution. Every Twilio conversation is matched back to the exact click that started it — fbclid, gclid, msclkid, ttclid, li_fat_id, plus all utm_* parameters preserved.

Campaign-ready conversion exports. Push qualified WhatsApp leads as conversion events into Meta, Google, TikTok, LinkedIn and Microsoft Ads. Smart bidding finally has a real lead signal to optimise on.

Server-side, no developer. No new Pixel events, no Tag Manager work, no engineering tickets. Twilio webhook in, attributed events out.

Pricing note

Twilio charges separately for messages and WhatsApp number access. WAct pricing is unaffected — we count attributed conversion events on our side, regardless of how many messages you send through Twilio. See Twilio's WhatsApp pricing for per-message and number costs, or compare WAct plans for tracking volume.
