Integrate sipi.bot with n8n

n8n workflows run on schedules — including at 2 AM. A firewall node before any paid step keeps the automation honest.

Step 1 — Add an HTTP Request node

Create an HTTP Request node pointing at /v1/transactions/evaluate with your key.

Step 2 — Branch on the decision

APPROVED → continue to the paid step. BLOCKED → stop and log. FLAGGED → pause for approval.

Step 3 — Schedule-safe rules

Add a time-of-day rule so overnight runs wait for a human.

Node config

HTTP Request → https://sipi.bot/v1/transactions/evaluate
Body: {"amount": 50, "merchant": "api.vendor.com", "category": "api"}
Branch: APPROVED → continue | BLOCKED → stop | FLAGGED → notify

Three branches, one deterministic decision.

FAQ

Does this work in self-hosted n8n?
