Hi and thanks for taking initiative to reach out. Here is the github discussion on integrating apps such as IFTTT, etc. into a new app called “Nextcloud Wires”. Nextcloud team has told us on Github that any of these integrations will be through an app rather than part of core.
Zapier wasn’t discussed, but general discussion previously took place in an earlier thread in this forum. IFTTT channels for Nextcloud
As you’ll see from our earlier efforts, Nextcloud team immediately denied our request for them to reach out to IFTTT, who handles new integrations in a similar manner to your Zapier response.
I’ve continued to reach out to IFTTT’s friendly team, but have made no headway since I do not work for Nextcloud as an employee.
Exit: perhaps you could write a script that uses cadaver or other webdav interface + inotify. This way Nextcloud will pick up changes made by your scripts.
