n8n REST API: Build Custom Integrations Without Vendor Lock-In
Deploy a managed n8n instance with full REST API and CLI access. Trigger workflows from your code. Pay per execution, not per step. German data residency included.
Why n8n API with Opsily
Managed hosting gives you enterprise infrastructure without the operational burden.
No Vendor Lock-In
n8n's REST API and CLI let you trigger workflows directly from your code. Export everything as JSON. Self-hosted means your data stays on your infrastructure, not a third party's. Unlike proprietary platforms, you own the entire stack.
Predictable Execution Costs
Pay per complete workflow execution, not per step. One complex workflow that costs 10,000 tasks on Zapier runs as 1 execution on n8n. Scale from 100 to 100,000 executions monthly. Your API rate stays constant. Opsily's infrastructure means zero throttling.
GDPR Data Residency
Every API call, workflow execution, and credential stays in Frankfurt infrastructure. EU data protection regulations fully met. Audit logs. Encrypted backups. Full compliance documentation provided.

Deploy n8n API in 4 Steps
From signup to your first API call takes under 3 minutes.
Choose Your App
Select an app to get started.
Deploy Your Instance
Opsily provisions a managed n8n instance in Frankfurt in minutes. REST API enabled by default. No configuration required.
Generate Your API Key
Create an API key in instance settings. Use it to authenticate REST calls from Python, Node.js, Go, Rust, or any language that supports HTTP.
Trigger Workflows Programmatically
POST requests to /rest/workflows trigger runs, fetch execution logs, manage credentials, and update variables. Webhooks handle inbound integrations too.
Scale Without Limits
Each execution is one workflow run. No hidden step charges. Opsily scales automatically. Run 10 workflows daily or 10,000. Same price, same speed.

n8n's REST API gives you complete control over workflow automation from your own application code.

n8n API Questions Answered
Get answers to common questions about REST API access, authentication, pricing, and deployment.
Every Opsily-hosted n8n instance comes with the REST API enabled by default. Log in to your instance, go to Settings > API, and generate an API key. Copy the key and add it to your application's HTTP headers as Authorization: Bearer YOUR_API_KEY. You can then make REST calls to trigger workflows, fetch execution history, manage credentials, and more. The full API reference is available at docs.n8n.io/api/.
