Supply the public page and checkout destination on either side of your handoff. We compare observable URL context without adding items, starting a checkout, or placing an order.
Supply the two public URLs on either side of the payment handoff. We compare URL-level campaign continuity and never add an item, start checkout, or place an order.
This tool answers: Does campaign context disappear before a payment-provider handoff?
Enable JavaScript to run the check — the diagnosis itself is free and needs no account.
A checkout provider is often a separate domain. That breaks first-party cookie access and can replace an acquired source with a payment referral, Direct session, or no attribution at all.
The browser cannot truthfully prove what a gateway stored in its session or webhook, but it can expose the first visible break: campaign context present before the handoff and absent on the explicitly supplied public destination.
These answer the questions this one tends to raise.
So you can trust the result — and your developer can verify it.
We do not discover or click checkout buttons. You provide the known public URLs, which are guarded and opened in one isolated browser session.
UTM and click-ID keys are compared before and after the boundary. The result explicitly states that referrer headers and provider-side session data need a test order to verify.
Clarvivo joins acquisition with payment truth even when customers move between domains and systems.
