I'm struggling to get a Survey123 webhook to work properly. The URL of the webhook leads to a self-written script that is accessible in the internet. It works just fine if I submit the survey123 form via the mobile app.
However, the webhook is not executed when I am submitting the form using a web browser. This was tested on multiple devices (desktop PCs and mobile devices) and also different forms. I can't figure out why this happens.
I submitted the form on the same device with a browser and with the app and got the described result. If I manually paste the URL in a browser, the webhook works fine as well.
Does somebody have an idea for the reason of this behavior? Any help is greatly appreciated!
