Freshpaint then hydrates the conversion event with the original click ID from the ad platform, ensuring the conversion is attributed to the correct source. Identity matching uses deterministic signals: email, phone, or a customer-provided ID. ### Enable Cross-Device Attribution Cross-device attribution is available on request. To activate it, contact Freshpaint Support or the account management team. Once enabled, the feature works automatically — no additional code changes are required. ### What's Next? * [**Identity Resolution**](/audiences/identity/identity-resolution.md) — Learn how Freshpaint resolves identities across devices and sessions --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://documentation.freshpaint.io/audiences/identity/cross-device-attribution.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
