FME Flow REST API V4: Information on all Workspace Apps?

We need a FME Flow data stream which generates an HTML page showing an index of all available FME Flow Workspace Apps on our FME Flow instance.

In FME Server 2022 REST API V3 we used [FME_Server_instance]/fmerest/v3/apps?.

In FME Flow 2025 REST API V4, when we use the analogue [FME_Flow_instance]/fmeapiv4/flow-apps?, we do not obtain a result.

Which is the appropriate call to obtain the information on all Workspace Apps available on an FME Flow instance in REST API V4 (as e.g. is [FME_Flow_instance]/fmeapiv4/repositories? to obtain all Repositories)?

We have the impression you don’t even understand what we need, or the difference between an ordinary workspace and a FME Flow Workspace App, respectively!
In general, we are quite frustrated that safe no longer maintains backward compatibility with FME Form, and Flow. If this parameter was accessible in FME Server REST API V3 (see top), why for %&*/ sake shouldn’t it also be accessible in FME Flow REST API V4.
We can't possibly have to search through all our code for missing compatibility issues and find workarounds for all of them with each and every single version upgrade: That defitely costs us far too much ressources! Please fix missing backward compatibilities auch as this one urgently and quickly!

The two calls give me identical results against an FME Flow 2024.1 environment

So you’re right, i don’t understand what you need. But i definitely understand the difference between a workspace app and a workspace. I suggest you raise an idea with Safe if you need something different as I neither work for or represent them :-)

    /fmeapiv4/apps/workspaces?

    /fmeapiv4/apps/automations?

    /fmeapiv4/apps/ar?

    /fmeapiv4/apps/galleries?

     

    These aren’t documented so use with caution

      Thank you for your try, ​@ebygomm.

      However I need to retrieve FME Flow Workspace Apps by API inquiry, and not ordinary workspaces, automations, ar, or galleries.

      Any more ideas?

      That is exactly what that does, hence the apps part of the rest api call

      /fmeapiv4/apps/workspaces?

      There's one call for each type of app - workspace apps, automation apps, ar apps and gallery apps

        I had some luck recently using the /dependencies endpoint

         https://docs.safe.com/fme/html/fmeapiv4/docs/index.html

         /dependencies endpoint to locate where the  resource “Type” is workspace app

        In workspace build out a few HTTPCallers and JSONFragmenters 

        some tips in this article https://support.safe.com/hc/en-us/articles/25407702974733-Using-the-FME-Flow-REST-API-V4-to-Create-Job-History-Reports

          Congratulations, now you gave me the clue:

          [FME_Flow_instance]/fmeapiv4/apps/workspaces? seems to be the solution!
           

          However, for some reason this is not listed in the FME Flow REST API V4 documentation!

          Have many thanks, ​@ebygomm!
