Is it possible to get the current FME Flow connection from within a workspace running on FME Form?

First read up about all the current functionality of Deployment Parameters

UI method

Under Flow > Jobs - find the workspace you run and open log

Under the “Request Data”

You will find the Deployment Parameters section, refer to the VALUES

REST API v4 method

To inspect jobs in the FME Flow REST API v4, use the Jobs endpoints:

• List job history: GET /jobs (use limit + offset for pagination). This gives you job records you can filter/sort in your client code.
• Inspect one job: GET /jobs/{id} to see details for a specific run.

Seems this endpoint only has the run, retrieve, cancel, job log and the status. Nothing about the request

To dive into the deployment parameters with REST… 

https://HOST.domain/fmeapiv4/docs/index.html#/dependencies

Seems to only be about creating and retrieve deployment parameters

In the v4 REST API docs (Help & Resources → REST API), create a token by signing in top right cnr. Then look under Repositories for the endpoint that returns the workspace file/content (download).

Build this out in FME Form

Once you have the .fmw, in a reader (fme workspace) you can parse it (it’s XML) and extract any deployment-parameter tokens/references.

Hi ​@j.botterill ,

thanks for taking the time to reply but that’s not really what I’m looking for. I know all about Deployment Parameters (they rock!). What I’m trying to do is figure out which FME Flow instance I’m currently connected to when running a workspace in FME Form.

When you connect to a specific FME Flow instance in Form (e.g. DEV, or PROD), Form will use the Deployment Parameter values specific to that instance, which is very handy. However, what I can’t seem to determine is exactly which instance I’m connected to.

The information is right there in the Form interface:

But I can’t seem to get at that information from within the Form workspace when it’s running.

The reason I want to know which Flow instance I’m connected to (e.g. DEV or PROD) is so that I can make my Form workspace dynamic and connect via the HTTPCaller to the correct instance when using the FME Flow API. The HTTPCaller requires a URL and authorization and those details will change depending on which Flow instance I need to connect to.

I hope this is a bit more clear for what I’m trying to achieve.

Watching with interest, i currently have some workspaces set up where I just have to choose dev/test/prod etc. and it will work out the url and authentication from that for some workspaces that make FME api calls.

I’m going to raise this as a support ticket with Safe Software because I feel like this should be out-of-the-box functionality but I’m not seeing that in my current build.

The solution that I’m using for now is to create Deployment Parameters on each of my FME Flow instances to return the instance URL and a web connection to connect to the instance.

I can then use these Deployment Parameter values in the HTTPCaller in my workspace to make the REST API connection:

I configure the FMEFLOW_API_CONNECT web connection with appropriate permissions for accessing the API calls that I need and I’ve created a specific user that is defined in the web connection. However, it would be nice if this could just use the currently logged in user in FME Form, without needing to create a custom user on FME Flow to achieve this.

Thanks for the update ​@nic_ran . Good to know for sure.
