Merchant Attribution

Overview

Merchant attribution is the process of determining which merchant, sub-merchant, store, or business account should receive credit for a crypto payment within a shared payment platform. A robust implementation treats the concept as structured payment data rather than as a label shown only on the checkout page.

The platform can use API credentials, business IDs, payment links, invoice ownership, dedicated addresses, metadata, and routing rules to connect a payment with the correct merchant ledger and settlement configuration. In practice, the system should preserve the original request, the observed blockchain or checkout evidence, and every status change that affects this value. This makes support investigations and financial reconciliation possible without reconstructing the payment from screenshots or mutable client data.

Attribution must be deterministic, tenant-isolated, auditable, and resistant to identifier tampering. The system should prevent a payment or invoice from being reassigned across merchants without controlled authorization and maintain clear ownership during refunds and disputes. The implementation should use exact asset precision, authenticated server-side updates, and idempotent processing wherever repeated API calls, blockchain observations, or webhook deliveries can occur.

It differs from invoice attribution, which matches a transfer to a particular invoice, although invoice ownership is often one of the strongest merchant-attribution signals. It should be interpreted alongside Invoice Attribution, Marketplace Seller Payment, Merchant Payment Address. These concepts belong to the same workflow, but each answers a different operational question and should not be collapsed into one ambiguous field.

A platform that serves many sellers can use the API key and invoice record to credit an incoming USDT payment to the correct seller’s balance. The practical test is whether a merchant can explain how the value was produced, verify it independently, and apply the same rule consistently when the payment is delayed, duplicated, partially paid, refunded, or reviewed manually.
