n8n proofs
n8n automation permission proofs
n8n workflows automate API calls at scale. When AI nodes or high-privilege integrations join those flows, operators need signed permission proofs before spend, export, or admin steps execute. AffixIO verifies allow or deny at the workflow boundary with ML-DSA-65 signatures and Merkle audit, beside n8n rather than replacing it.
Definition
n8n permission proofs are signed allow or deny artefacts workflows present before consequential automation steps proceed.
Field note. Workflow flags can be edited by anyone with n8n access. External verify proofs survive workflow tampering.
Verify at the n8n HTTP step
Add an AffixIO verify HTTP Request node before payment, CRM export, or infra mutations. Issue proofs when workflows are published or when operators grant run authority. Deny stops the branch. Allow continues with Merkle metadata written to your logging sink.
REST endpoints integrate without a proprietary n8n plugin. Keep workflow logic in n8n. Keep policy decisions at AffixIO verify.
Governed automation beside shadow AI
Pair n8n gates with shadow AI runtime controls so unapproved automations cannot bypass verify by calling APIs directly.
Start with finance and customer-data workflows. Expand to agentic commerce orchestration as AP2 and UCP pilots mature.
Verifier placement for n8n permission proofs
Wire AffixIO verify immediately before the boundary where n8n permission proofs applies: checkout authorisation, MCP tool invocation, age gate, or offline scan. Issue proofs when policy is satisfied. Present at the edge. Gate on signed allow or deny.
Train support on deny retrieval: Merkle ref lookup should not require engineering access. Document which circuit version was active when the proof was issued.
AP2 intent gap
Visual automation without cryptographic policy
n8n makes it easy to wire credentials into flows. It does not produce auditor-grade evidence that a step was permitted under policy at runtime.
Shared credentials in workflow nodes
One n8n credential unlocks every downstream HTTP call.
AI nodes amplifying scope
LLM steps choose tools without independent eligibility verification.
No anti-replay on triggered runs
Webhook retries can duplicate spend without spent-proof.
Shadow workflows
Personal n8n instances connect to production APIs alongside governed ones.
Issuer split
n8n automation runs need permission proofs, not workflow flags
n8n workflows that trigger payments or data exports need verifier-checkable proofs, not boolean flags in the workflow JSON. Issue at policy satisfaction, verify before each side-effect node.
Tag high-risk n8n workflows
Mark flows that spend, export, or change production state.

Mint eligibility bound to workflow ID and operator policy.
Insert verify nodes upstream
Gate branches on signed allow or deny responses.
Log Merkle refs from executions
Attach audit pointers to n8n execution history exports.
