What is Conversions API (CAPI)?

Meta's Conversions API sends purchases and other events from your server or store platform straight to Meta, so conversions are still measured when browser tracking is blocked.

CAPI works alongside the Meta Pixel. Sending the same event from both, with a shared event ID, lets Meta deduplicate it and gives better measurement than either alone.

Better event data improves both reporting and the optimisation Meta does for your campaigns.
