Start a job. Check its progress. Handle what comes back. Practise the pattern with an editable n8n workflow and a simulated API before adapting it to your project.
No signup or payment. Evaluation licence included. An independent setup trial is still pending.
15 casespassed through the n8n CLI

From the actual practice run. The job completed after three status checks and returned “Synthetic result.” Checked in the n8n 2.45.6 editor with synthetic data.
Inside the preview
An example you can inspect.
Follow the workflow, run synthetic scenarios, and use the notes to understand what needs changing for a real API.
01
Workflow JSON
A manual n8n example that keeps job state separate from status responses.
02
Simulated job API
Practise with synthetic jobs. No paid API account or credentials required.
03
Isolated practice setup
Docker Compose files, a local editor gateway, and setup instructions.
Map the example to your provider’s endpoints, fields, and status values.
06
Test evidence
Read the recorded outcomes, version details, and handover worksheet.
Check the edges
A pending job needs a stopping rule.
A successful first request is only the beginning. Inspect what happens when the next response loses context, the job fails, or the wait goes on too long.
The poll count or elapsed deadline stops an unfinished job.
Before you start
Bring a test environment.
Docker Engine and Compose v2, spare memory, and a free local port 15678.
Familiarity with n8n nodes and basic HTTP requests.
Time to adapt and test your provider’s contract separately.
The primary demo is self-hosted. n8n Cloud and other n8n versions have not been verified.
What is still being checked?
The recorded tests used synthetic workflow variants imported into n8n and executed through its CLI, with request-log checks. Clipboard import and four manual editor cases were also checked: completion, failed job, poll-limit exhaustion, and elapsed-deadline exhaustion. An independent clean-setup trial is still pending.
The archive includes the compatibility record and test evidence. These results do not establish production reliability.
Frequently asked questions
Is this ready for production?
This is a development preview for private evaluation. CLI tests passed on n8n 2.45.6. Clipboard import and manual editor cases were also checked. An independent setup trial and real-provider testing remain outstanding.
Will it work with my API?
You must adapt the endpoints, authentication, status mapping, and result validation to your provider, then test those changes. Universal API compatibility is not claimed.
Does it retry failed requests or prevent duplicate jobs?
No. HTTP errors stop the workflow in this version. Running it again can create a new job. Automatic request retries, cross-execution deduplication, and restart recovery are separate work.
What does the preview licence allow?
The included evaluation licence permits private inspection, execution, and modification. It does not grant resale, public redistribution, or a production-support commitment. A commercial licence has not yet been issued.
Is the free practice pack the same download?
No. The free practice pack is a standalone Node.js simulation. This preview includes an importable n8n workflow, a mock API, and the isolated Docker practice setup.
Prefer a smaller first step?
Try the standalone practice pack.
Explore synthetic polling responses with Node.js, without importing a workflow or running n8n.
