ArcGIS Architecture Center > Webhooks
Several ArcGIS applications or systems make native use of webhooks, including:
...Survey123 Field App and web form webhooks
That wording makes me wonder if the two applications are considered to be separate entities, requiring separate webhook configurations.
Does a Survey123 webhook need to be set up separately in both the web form and the field app? Or do we only need to set up the webhook in the web form, which would be automatically honored in the field app?
