My app’s URL: app.weeklystyle.de
I have tried to create a webhook in a custom action. The dialog to enter the name and the url shows up, but when I click in one of the fields the dialog closes.
I use this browser:
The workaround is to create a button and create the webhook with that button. Then I could choose it in my custom action.
The web hook didn’t work when the app is running as installed app on my ipad mini.
On my Android Phone and on my windows machine is the webhook excecuted like expected.
