n8n — Workflow Automation

Connect DPX to n8n using the HTTP Request node. n8n’s no-code interface lets you build settlement workflows, trigger alerts on peg deviations, and route transactions based on live ESG scores.

Workflow: Price a settlement

5. HTTP Request — GET /reliability
6. IF — Branch on isHealthy and stability.currentScore >= 90
7. HTTP Request — POST to your settlement system with quoteId

Self-hosted n8n

If running n8n locally, both oracle URLs are reachable at localhost:3000 and localhost:3001.

For n8n Cloud, you’ll need the hosted production endpoints — these are provided upon beta approval.
