Yes, that helped a lot - have it working perfectly now - wasn’t as difficult as I thought!!
Can I get the Webhook to return the user to the web page that they came from after the form has been submitted? I have added a new Set to the end of the workflow and defined a string with the URL - then, in the Webhook, set:
Response Code: 301
Response Node: Last Node
Response Data: First Entry JSON
This results in the page displaying the JSON data defined in the last Set node and not an actual redirect to the URL - is it possible to do this?
Btw. just added a new answer to the linked post. The reason is that because of a new functionality that got added a few months ago the same can now be done simpler.
