Enable CORS in Freescout API
-
Hi and welcome!
Not exactly sure how the communication is, but you may want to set CSP config for the app for a start https://docs.cloudron.io/apps/#custom-csp
Headers as such should be forwarded normally by the reverse proxy, so if you hit this issue we have to debug this somehow with your setup to fully understand the issue.
If Freescout as such does not support CORS then this is an upstream issue with Freescout (or in this case the API addon) Usually we have seen that they are quick to fix issues once reported

While CORS can be enabled in the reverse proxy, the correct place to do this is in the app itself. The app alone knows if it's API has been designed and tested for Cross Origin use cases. Enabling it without understanding the app will is a security issue. So, I guess this comes down to asking Freescout to add these headers in their responses.
@paridata If you report this, can you please link the github issue or support request here? I am happy to chime in.

After doing the upgrade and specifying the allowed host in the app and clearing the app's cache, I'm still not getting the desired behaviour. Is there some sort of caching happening on the cloudron side? I've tested on my side in an anonymous browser window. As far as I know the ninoxdb app does not intercept/cache the responses from cross origin requests.
Can you guys say if the app is doing what it should?

I am not aware of any such caching on Cloudron side. This is a bit hard to test without that plugin.
There is a new freescout version coming as well, was released just today. Maybe there were some changes needed as well. I am just building the new app package.

let's see...
doing the equivalent to
curl -X GET -G "https://ticket.paridata.net/api/conversations/6951" -H "X-FreeScout-API-Key: [api key removed]"
