Get a Refusal Record by transaction ID
Returns the signed Refusal Record kept when a policy refused a transaction: the decision, the rule that refused, the facts it saw and the signature.
Authorizations
Caller API key issued by scripts/generate-api-key.ts. Sent as Authorization: Bearer . Verified against a stored SHA-256 hash in constant time by packages/api/src/auth/StaticKeyAuthenticator.ts. Required on every route not listed as exempt in this document's top-level description. See /api-reference/authentication.
Path Parameters
The id of the refused transaction. In the sandbox, the value shown is a seeded transaction kept for these docs. To try your own, run the playground and use the businessTransactionId it prints.
Response
The Refusal Record.
Response returned by GET /refusal/{businessTransactionId}. A bare Refusal Record, no wrapper.
Unique Refusal Record identifier.
Business Transaction this refusal is about.
Immutable result of evaluating an Intent against a Policy. Decision does not create authority, grant authorization, or modify Intent; it only records the outcome of deterministic Policy evaluation.
The Intent snapshot the signals were evaluated against: target and parameters only, present for every refusal, not only binding violations.
Canonical hash of this Refusal Record, same convention as ExecutionTrustRecord.trustRecordHash.
Cryptographic signature over the canonical Refusal Record, signed with the same key as ExecutionTrustRecord, one root of trust for both approvals and refusals.
UTC timestamp when this Refusal Record was created.
Present only when the rejection came from SignalIntentBinder. Absent (not an empty array) for an ordinary PolicyEngine.evaluate REJECT that never reached binding-violation logic at all.
Authenticated caller who submitted the rejected request. Absent when caller authentication is disabled.
SHA-256 hash of the policy content that decided the refusal, the same value an Execution Trust Record carries in transaction.policy.contentHash. Inside the signed record. Absent on Refusal Records written before 2026-10-06.
