If you use N8N, you can send CMS form responses to it.
How to set this up in CMS
In your CMS, navigate to the form you want to link to N8N. Click the 'Actions' tab, and click the button '+ New action'. From the dropdown, select 'Send to N8N'.
Then, you’ll need to enter an endpoint and a secret key. This is information that you need to get from your N8N account, see below. When done, click 'Save action'.
How to set this up in N8N
Log in to your N8N account. Double-click the webhook that you have set up as the start of your workflow. This webhook is the url that you enter at 'N8N endpoint' in CMS. Make sure that the authentication type is 'header-auth'. Open the action, and you’ll see that the secret key is editable. Copy this secret key into your CMS as well (see above).
