Meta's ads system learns from what you tell it. If you only tell it "someone filled a form", it finds more people who fill forms, including people who never pick up. If you tell it "this lead came for a site visit" and "this lead booked", it can look for more people like them.
What the Conversions API is
The Conversions API (often called CAPI) is Meta's way for your CRM to send events back to Meta from a server. An event is a simple message like "lead X reached site visit". Meta matches it to the original lead form, so the ad learns.
Which events to send
Keep it to the steps that really mean a buyer. Sending every small status change adds noise.
- Site visit done
- Booking or token paid
What you need
- Leads that came from Meta lead forms
- A CRM that records each lead's stage honestly
- The CRM connected to your Meta business and pixel or dataset
How Call Pro AI does it
When a Meta lead's stage moves to site visit or booking in Call Pro AI, it can send that event back to Meta. The owner connects Meta once from the admin dashboard.
The short version
Tell Meta about the leads that matter, not just the forms. Honest stages in your CRM are what make this work, so make sure telecallers update the stage after every call.
