Conversion API (CAPI) Activations to Ad Audiences Partner Platforms

Send online and offline conversion events and data directly to advertising platforms. CAPI integrations bypass segment creation and deliver event signals in near real-time for superior campaign optimization and clearer attribution analytics.

These platforms are supported for CAPI activations:

• LinkedIn CAPI
• Meta CAPI
• TikTok CAPI
• Snapchat CAPI

Considerations

• CAPI uses DMO-based (streaming) activation, not segment-based activation. You select a data model object as the event source rather than an audience segment.
• Each platform enforces API rate limits. Events that exceed these limits or that are older than the platform's maximum lookback window are rejected.
• By default, each CAPI activation publish sends a maximum of 30,000 records per batch. For segments larger than 30,000 records, the remaining records are activated in batches across successive refresh cycles, so the full audience may not appear on the partner platform immediately after the first publish. This limit can be increased to 200,000 upon request.
• To provide a broader set of customer records for identity enrichment, create a data graph and associate it with your CAPI activations. See Data Graphs.
• Mapping optional attributes such as first name, last name, country code, and external IDs improves user match rates on the partner platform.
