Attesto nodes for n8n: turn workflow steps into
verifiable evidence.

  • Attesto (action): Log Event, Log Typed Compliance Event
    (Model Decision / Human Override / Incident Report / Data Access),
    Get Receipt, Verify Receipt (offline) — verification recomputes the
    canonical hash and Ed25519 signature locally against the witness key
    pinned in your credential; Attesto's servers are not consulted.
  • Attesto Trigger: starts a workflow only on signature-verified
    Attesto webhooks (HMAC over timestamp.body, constant-time compare,
    300 s skew). Forged or stale deliveries get a 401 and never run a node.

Install

Community nodes → Install → n8n-nodes-attesto, or:

npm install n8n-nodes-attesto

Create an Attesto API credential with your API key (and the witness
public key if you use offline verification; the webhook secret for the
trigger). Keys live in n8n's credential store, never in workflow JSON.
