# Integration using the n8n service
[*n8n*](https://n8n.io/) *is a platform for visual workflow automation and integration of various web services and applications without writing complex code or involving developers.*
In Selarti, you can set up an integration with any external service using webhooks.
### Setting up the integration in the n8n dashboard
Sign up for [the n8n service](https://app.n8n.cloud/login). To create a new workflow, click the *«+»* icon on the left side of the screen and select *«New workflow»*.
In the center of the screen, click *«Add first step...»*. In the window that opens on the right, enter *«Webhook»* in the search field. Select *«Webhook»*.
A webhook settings window will open. In the *«HTTP Method»* field, select *«POST»*. Click the *«Test URL»* link above to copy the address — you will need it in the next step. Then click *«Listen for test event»* so that n8n starts waiting for a test webhook from Selarti.
{% hint style="info" %}
Please note that after clicking «Listen for test event», you have 120 seconds to send a test webhook from Selarti. If the webhook is not sent within this time, click «Listen for test event» again before sending the test event.
{% endhint %}
### Setting up the integration in the Selarti dashboard
Go to the Selarti dashboard. In the left sidebar, open [*«Integration»*](https://selarti.com/panel?menu=integration), then click *«Create integration»* in the upper-right corner. Select *«n8n»* as the integration type.
Enter any name, then paste the link copied from the n8n dashboard. Click *«Send test webhook»*.
If everything is set up correctly, the link entered in Selarti will be highlighted in green.
Select the required trigger types from the *«webhook type»* dropdown list and click *«Create integration»*.
For more information about the parameters sent by webhooks and custom API with custom fields, see the article [«Integration with an external messenger»](/manual-en/external-integrations/integration-with-an-external-messenger.md).
### Checking the webhook and switching to production mode in n8n
Go back to n8n and check the webhook settings window. Information about sending data to the test URL will appear in the field on the right. After a successful test, switch to the *«Production URL»* tab and click the link to copy it.
Then go back to Selarti, open the *«Integration»* section and select the integration you created. Replace the URL with the production URL and click *«Save»*.
{% hint style="warning" %}
The test URL is intended for testing the setup only. For actual operation, use the «Production URL».
{% endhint %}
### Creating an action in n8n
Close the webhook settings window in n8n and add the required action to the workflow. There are many options available, as n8n supports a large number of actions.
The integration is ready!
### Example: setting up data transfer to Google Sheets
For this setup, you will need a Google account and a Google spreadsheet with headers created in advance.
Click the *«+»* icon next to the *«Webhook»* node.
In the window that opens on the right, select *«Action in an app»*.
In the next window, enter *«Google Sheets»* in the search field and click the *«Google Sheets»* result.
Select the *«Create spreadsheet»* action.
A window will open. Click *«Sign in with Google»*.
Select your Google account and specify the following parameters:
* *Resource* — *Sheet Within Document*.
* *Operation* — *Append Row*.
* Document — select the required spreadsheet.
* *Sheet* — select the sheet.
* *Values to Send* — map the event values you want to transfer to the spreadsheet columns. To do this, drag a value from the list on the left side of the settings to the required row with the column header.
Click *«Execute step»* at the top.
The data available for configuration will appear on the right. Close the settings window.
After configuring all actions, *click «Publish»*.
In the window that opens, enter any name and click *«Publish»*.
