Hi, have an issue with a Webhook in a Public App (not Pro)?
I have a public app with a form that on submission should trigger a Webhook.
The Webhook does not trigger when submitting the form **but** , when I’ve changed the settings to Public with e-mail it worked perfectly!
Am I missing something? is there any limitation on Webhooks in public Apps?

Webhooks currently require a user to be signed in to trigger.

Ciao @david, do you think webhooks will work with Public apps in the future?

Even if they won’t, there will always be the option of using Apps Script to post to a web hook.

Thank you @Darren_Murphy, how can be done? Via the google sheet?

Yes, from the Google Sheet using Apps Script.
If you’ve never used Apps Script before there is a learning curve, but it can be done.

Thank you @Darren_Murphy 🙂
I wrote my script in AppScript and it works! I can trigger the webhook and pass the values. Now the problem is how to trigger the event in glide, for example by pressing a button. Do you have any ideas?

All you need to do is create a trigger script to “watch” a cell/range in your spreadsheet, and then use Glide to alter a value in that range.
If you look at my [JSON/API tutorial](https://community.glideapps.com/t/using-app-script-with-a-json-api/20051), I use exactly that technique there.
