Donation Checkout

Overview

Donation checkout is a payment flow designed specifically for voluntary contributions rather than product purchases. It can let donors choose an amount, currency, campaign, recurring schedule, anonymity preference, message, and payment method.

The checkout should explain fees, receipt eligibility, data use, and whether the recipient receives the donated asset directly or after conversion. The recipient should also preserve donor privacy, campaign attribution, and the exact settlement evidence. A complete record for Donation Checkout should show where it depends on Donation Link and how it differs from Donation Address. Related operational concepts include checkout and payment method. They should remain connected through identifiers and evidence without being treated as the same payment state, control, or financial result.

For Donation Checkout, particularly where Donation Link is involved, the recipient should also preserve donor privacy, campaign attribution, and the exact settlement evidence. A mature implementation of Donation Checkout should separate donor intent from payment mechanics. The authoritative record for Donation Checkout should also show the rule version, responsible system, permitted state transition, and any downstream action such as fulfillment, settlement, refund, or manual review.

Risks include fake campaign branding, privacy leakage, recurring donations without clear consent, stale payment instructions, unsupported assets, and abandoned sessions incorrectly counted as donations. Testing should cover duplicated and out-of-order events, incorrect asset or network data, late transactions, provider outages, retries after uncertain responses, and manual intervention after one subsystem has already changed state.

Governance should connect Donation Checkout to the original obligation, payment instructions, observed transaction, internal state, financial posting, and any fulfillment or refund. The decisive principle remains that donation checkout should minimize data while clearly handling campaign purpose, recurring consent, crypto instructions, payment assurance, privacy, valuation, and receipt generation.
