Webhook JSON API endpoint
- n8n
- beginner
- 3 nodes
- ~2 min setup
Tested on n8n 2.25.7 · Last verified 2026-06-21 · v1.0
- Trigger Webhook POST /webhook/my-endpoint Receives JSON from any form, app or script
- Action Edit Fields (Set) Shape the response Wraps the body, adds ok: true
- Action Respond to Webhook Return JSON to the caller
What it does
Turn n8n into a no-code JSON API: a Webhook receives a POST, an Edit Fields node shapes the response, and Respond to Webhook returns it — a working HTTP endpoint with zero credentials.
- Webhook
- Edit Fields
- Respond to Webhook
How to import it into n8n
- Copy the workflow JSON Use the Copy JSON button above (or download the .json file).
- Open your n8n canvas In n8n, open Workflows and create a new, empty workflow.
- Paste to import Press Ctrl/Cmd+V on the canvas, or use the ⋯ menu → Import from File / Import from URL. n8n recreates every node.
- Connect your credentials Open each node flagged with a credential placeholder and select your own account — see the credentials table below.
- Test, then activate Run once with test data to confirm the path end-to-end, then toggle the workflow Active.
Notes for this template
- After importing, open the Webhook node and copy its Production URL — that is your live endpoint.
- Change the path ("my-endpoint") to something meaningful for your use case.
- The Set node returns the posted body wrapped as { ok, received }. Edit it to shape your own response.
- To add logic — validation, calculations, branching — swap the Set node for a Code node.
Credentials you’ll connect
No external credentials required.

Do I need any credentials?
No. This template uses only built-in nodes (Webhook, Edit Fields, Respond to Webhook) — there are no API keys or accounts to connect.
How do I get the webhook URL?
After importing, open the Webhook node and copy its Production URL (it ends in /webhook/my-endpoint). You can change the path to anything you like.
Has this really been tested?
Yes. It was built, executed and re-import-verified on a real n8n 2.25.7 instance — a POST to the webhook returns the JSON response shown above.
How do I change what it returns?
Edit the "Edit Fields" (Set) node to add or rename fields, or replace it with a Code node for custom logic.
Is it free?
Yes — free to download and use, no signup and no email required.
