Transaction Assurance

Choose this endpoint when you need independent, third-party verification of a payment transaction's full lifecycle — authorization, settlement, delivery, and acceptance — and require a signed portable receipt as cryptographic proof. Prefer it over simple payment status checks when auditability, non-repudiation, or cross-agent trust is required, such as before releasing goods, granting access, or chaining agent actions that depend on a confirmed prior payment.

• Transaction not found or unrecognizable — returns error indicating the provided transaction data could not be located or matched
• Authorization check fails — receipt indicates the transaction was not properly authorized
• Settlement not confirmed — assurance result shows settlement has not completed or is pending
• Delivery unverifiable — endpoint cannot confirm delivery status and flags it in the receipt
• Malformed input — missing or invalid transaction fields result in a validation error
• Deterministic acceptance not met — transaction fails acceptance criteria and receipt reflects rejection
