The Pixel is ideal for tracking website activity and attributing conversions to specific ad campaigns, while the CAPI provides a more robust solution for tracking offline events, cross-device conversions, and other non-website interactions. Advertisers may choose to use one or both of these tools depending on their tracking needs and objectives.

Remarks: Starting with Graph API version 17 onwards, released on May 23, 2023, Offline Conversions API will no longer support offline events. We anticipate that the Offline Conversions API will be discontinued in the third quarter of 2024. We recommend that advertisers with Offline Conversions API integrations convert their integration into a Conversions API integration and do not update their Offline Conversions API until they have successfully done so.
