Benefits of measuring with CAPI

  • Recover lost conversions

    The pixel loses data to blockers and cookies; CAPI recovers up to 30% of those conversions.

  • Real ad ROI

    Tie every dollar spent on ads to a concrete outcome: sales, leads or signatures.

  • Better-optimized campaigns

    Meta receives accurate conversion signals and adjusts targeting automatically.

  • Omnichannel attribution

    Web, WhatsApp, CRM, apps and physical points of sale, attributed to the right campaign.

Frequently asked questions

What’s the difference between CAPI and the pixel?

The pixel measures from the browser and loses data to blockers and cookies. CAPI sends conversions from the server, more completely.

Can I attribute sales closed on WhatsApp?

Yes. Conversions that happen in conversations, in the CRM or in a physical store are also reported to Meta.

Do I have to stop using the pixel?

No. CAPI complements it: both work together for more accurate measurement.

What do my campaigns gain?

Meta optimizes with real business signals and you measure return on verified sales and leads.
