Three buttons in the [n8n](https://learn.ynteractive.com/content/tool/n8n) editor do three different jobs, and mixing them up is the most common reason a workflow 'works in the editor' but not for real. In this free lesson you use a practice copy of the n8n editor on a small, already-built workflow for a made-up bookkeeping office: a [Webhook](https://learn.ynteractive.com/content/lovable-n8n-web-app-ai-backend) catches a new-client form, Edit Fields picks out the email and name, and Google Sheets adds a row. You run one node with Execute step, pin [test data](https://learn.ynteractive.com/content/glossary/test-data), run everything with Execute workflow, publish, copy the [Production URL](https://learn.ynteractive.com/content/glossary/webhook-test-url-vs-production-url), then change a node and publish again.

### The 5 parts, in short

1. Execute step: Open a node, Try Execute step, Stop the wait, Close the node.
2. Pin test data: Open the Webhook, Add test data, Save it as pinned data, Close the Webhook, and 3 more steps.
3. Execute workflow: Execute workflow, Check the real result, Back to n8n.
4. Publish: Publish, Open the Webhook, Production URL, Copy it, and 1 more step.
5. Change it and publish again: Make a change, Add a field, Close the node, Publish again.

## Execute step: run one node

Open a node and click Execute step at the top of its middle panel. n8n runs that node using the data from the node before it, and shows the result in the OUTPUT panel on the right. It is the fastest way to check one change.

If the node before it has no data yet, the INPUT side says No input data with an Execute previous nodes button. Clicking Execute step anyway makes n8n run the earlier nodes first, and a [Webhook](https://learn.ynteractive.com/content/glossary/webhook) trigger then just waits for a test call. Stop it, and pin test data instead.

## Pin test data so you stop resending the form

In the Webhook node, click the pencil above the OUTPUT panel, paste a sample submission and save. The banner reads This data is pinned for test executions, and every test run uses it until you unpin it. Form fields arrive inside body, so the email is {{ $json.body.email }}.

## Execute workflow: run everything, then check the real result

Execute workflow, at the bottom of the canvas, runs the whole workflow. Each node gets a green check and the lines show how many items passed. A green check means the node ran, not that the output is right, so open the sheet and look at the new row. In the lesson the Service column is blank because no field sends it yet.

## Publish and the Production URL

Saving does not turn a workflow on. The Webhook's Test URL only listens while you click Listen for test event in the editor. Click Publish at the top right to make the workflow live, then open the Webhook, switch to Production URL and copy it into your form. The production address has /webhook/ in it, not /webhook-test/.

After you change a node, the live workflow is still the old version. Publish lights up again; click it so real submissions use your change.

## Try it yourself, free

Reading the steps is a start. Doing them is how it sticks. The interactive module walks you through every click in a practice copy of n8n, checks each step, and never touches your real accounts.

## Step by step: n8n: Execute Step, Execute Workflow and Publish

All 23 steps of the interactive module, in order. In the module you watch each one, then do it yourself in a practice copy that checks your work.

### 1. Execute step

1. **Open a node.** This workflow is already built: a **Webhook** gets the intake form, **Edit Fields** picks out the email and name, and **Append row in sheet** saves them. Double-click **Edit Fields** to open it.
   This is a small workflow for Maple Street Bookkeeping. A webhook gets the new client form. Edit Fields picks out the email and name. Then a Google Sheets node adds a row.
2. **Try Execute step.** The **INPUT** side says **No input data**: the Webhook before it has never run. Click **Execute step** anyway, at the top of the middle panel.
   Look at the left side. It says no input data. The webhook before it has never run.
3. **Stop the wait.** n8n runs the earlier nodes first, so the **Webhook** is now waiting for a test call that will not come. Click the **stop** button (the square) next to the spinner.
   With no input, n8n runs the earlier nodes first. So now the webhook is waiting for a form to arrive. Nothing is coming.
4. **Close the node.** Instead of waiting for a real form, give the Webhook some test data. Close this node with the **X** at the top right.
   Instead of waiting for a real form, you'll give the webhook some test data. Close this node.

### 2. Pin test data

5. **Open the Webhook.** Double-click the **Webhook** node.
6. **Add test data.** The **Test URL** only works while you test in the editor (that is what **Listen for test event** does). You can skip the form for now: click the **pencil** at the top of the **OUTPUT** panel to type sample data.
   See the Test URL. It only listens while you click Listen for test event, here in the editor. You don't need a real form right now.
7. **Save it as pinned data.** A test form submission is already filled in. Notice the form fields sit inside **body**. Click **Save**.
   Here's a sample form submission. Notice the form fields sit inside body.
8. **Close the Webhook.** The banner says **This data is pinned for test executions.** From now on, test runs use it instead of waiting. Close the node.
   The banner says this data is pinned for test executions. Test runs now use it, instead of waiting for a form. Close the node.
9. **Open Edit Fields again.** The Webhook now shows a pin. Double-click **Edit Fields**.
   The webhook has a little pin on it now.
10. **Execute step.** The **INPUT** side now shows the pinned data. Click **Execute step**.
    This time the input side shows your test data.
11. **Read the output, then close.** Only this node ran, using the data from the node before it. The **OUTPUT** panel shows **email** and **name**, filled in by **{{ $json.body.email }}** and **{{ $json.body.name }}**. Close the node.
    Only this one node ran. It used the data from the node before it. On the right, the output shows the email and name. That's what dollar json dot body dot email pulls out. Close the node.

### 3. Execute workflow

12. **Execute workflow.** Now run everything. Click **Execute workflow** at the bottom of the canvas.
    Now run the whole thing.
13. **Check the real result.** Every node has a green check and **1 item** on its line. Green checks mean each node **ran**, not that the result is right. Open the **New clients** sheet tab to check.
    Every node has a green check. But a green check means the node ran. It doesn't mean the output is right.
14. **Back to n8n.** Row 2 has Dana’s email and name in the right columns. That is the real check. **Service** is blank: nothing sends it yet. You will fix that after you publish. Go back to the **n8n** tab.
    Row two has the email and name, in the right columns. That's the real check. Service is blank, because nothing sends it yet. You'll fix that later. Go back to the n8n tab.

### 4. Publish

15. **Publish.** Your work is saved, but saving does **not** turn the workflow on. Real form submissions only run it once it is published. Click **Publish** at the top right.
    Your work is saved. But saving does not turn it on. Real forms only run it after you publish.
16. **Open the Webhook.** Now the form needs the live address. Double-click the **Webhook** node.
    Now the form needs the live address.
17. **Production URL.** Under **Webhook URLs**, click **Production URL**.
18. **Copy it.** The production address has **/webhook/** in it, not **/webhook-test/**. It works all the time while the workflow is published. Click the URL to copy it, then paste it into your form.
    The production address says webhook, not webhook test. It works all the time, as long as the workflow is published. That's what goes in your form.
19. **Close the Webhook.** Close the node.

### 5. Change it and publish again

20. **Make a change.** Now fix the blank **Service** column. Double-click **Edit Fields**.
    Now fix that blank service column.
21. **Add a field.** Click **Add Field**. We will fill it in as **service** = **{{ $json.body.service }}**.
    It becomes service, from dollar json dot body dot service.
22. **Close the node.** Your change is saved in the editor. Close the node.
    The change is saved in the editor. Close the node.
23. **Publish again.** The live workflow is still the **old** version: real forms still skip the service. **Publish** lights up again because you have changes that are not live. Click **Publish**.
    Here's the catch. The live workflow is still the old version. Real forms still skip the service. Publish is lit up again, because your change isn't live yet.

## Frequently asked questions

**What is the difference between Execute step and Execute workflow in n8n?**

Execute step runs the one node you have open, using the data from the node before it. Execute workflow runs every node from the trigger onward.

**Why does my n8n webhook work in the editor but not from my form?**

The Test URL only listens while you test in the editor. Publish the workflow and use the Production URL in your form.

**Do I need to publish again after editing a workflow?**

Yes. Edits are saved, but the live version stays the same until you click Publish again.

**Does the lesson touch my n8n account?**

No. It is a practice copy of the editor. Nothing runs, and no account or sheet is touched.
