Verify cryptographic chain integrity of audit log
Walks the prev_hash -> entry_hash chain for the entity’s audit log and
returns whether the chain is intact. A broken chain indicates tampered or
deleted rows. On a clean system this always returns {verified: true}.
Authorizations
API key issued per entity via Settings > Developers > API Keys.
Each key carries scopes (e.g. orders:read, products:write).
Bearer token format: Authorization: Bearer ark_live_ent_Test keys use ark_test_ent_. Both are issued per entity
via Settings > Developers > API Keys.
Body
Response
Chain verification result
Result of the cryptographic chain integrity check on the audit log. A clean system returns {verified: true, chain_length: N}. A tampered or deleted row returns {verified: false, broken_at: , broken_reason: ...}.
audit_chain_verification Number of rows walked during verification.
ID of the first row where the chain broke (null when verified=true).
Reason code for the chain break (null when verified=true).
prev_hash_mismatch, entry_hash_mismatch, missing_row, null_hash
