It allows you to securely send offline conversions data to Meta, enabling better measurement, attribution, and optimisation of ad campaigns. By integrating Facebook Enhanced CAPI with Zeotap CDP, you can seamlessly activate offline event data for Meta Ads. Zeotap CDP ensures that conversion data is securely collected, transformed, and transmitted in compliance with data privacy regulations. This integration helps you: * Improve campaign performance with accurate conversion tracking. * Optimize audience targeting and bidding strategies. * Maintain compliance while sharing first-party data with Meta. ### Sample Use Cases #### Retail Offline Purchase Attribution If you run physical store promotions via Facebook Ads, you may want to track in-store purchases attributed to these ads. By using Facebook Enhanced CAPI, you can send hashed customer identifiers and purchase details to Meta through Zeotap, improving attribution accuracy and optimizing your ad spend. #### Lead Generation for Services If you collect leads offline (for example, at events, call centers), you can ensure accurate attribution by sending hashed lead data to Meta via Enhanced CAPI, even when cookies are restricted. ## Supported Identifiers This integration supports the following identifiers for matching: * Hashed Email Address (SHA256) * Hashed Phone Number (SHA256) * Hashed First Name & Last Name (SHA256) * Mobile Advertiser ID (not hashed) * External User ID (not hashed) It also supports sending attributes such as Date of birth, Gender, City and so on. ## Available Actions * **Send Offline data to FB Enhanced CAPI**– Enables sending offline event data for better attribution and optimisation in Meta Ads. ## Prerequisites Ensure you have the following in place before setting up Facebook Conversions API: * A Meta Business Manager account. * A Meta Pixel linked to your Business Manager. * A dataset configured to store conversion data. * A system user with the required permissions. * OAuth credentials or a system user access token. * App Review approval with Ads Management permissions. ## Components of Facebook Conversions API Before creating a destination in Zeotap CDP, ensure you have the following details: * Meta Pixel ID – Required to associate conversion data with your Meta Ads account. * Event Name – Specifies the type of event (for example, "Purchase", "Lead"). * Event Time – Unix timestamp of when the event occurred. * User Data – At least one identifier (email, phone, name, madid, or external\_id) is required for matching. * Custom Data (for Journeys only) – If sending purchase data, currency and value are mandatory. **Note** *To learn how to obtain these components, refer to this [documentation](/articles/integrate-customer/facebook-enhanced-conversions-api-capi#components-of-facebook-conversions-api).* ## Create a Destination for Facebook Conversions API Perform the following steps to create a Destination for Facebook Conversions API: Log into the Zeotap CDP App and go to the **DESTINATIONS** application.
