Parameter that shows both database and web connections?

I haven’t used the FME connection API, but isn’t it possible to retrieve a list of all available connections with it?

If so, you could perhaps use a scripted selection parameter to present the resulting list of connections to the user: https://docs.safe.com/fme/html/fmetools/fmetools/scripted_selection.html

Thanks ​@david_r, but I don’t believe there is a way to get all connections via this method. For instance, FMENamedConnectionManager allows for getNamedConnection(), but a name is a required input.

I presume that this will likely be a security thing

Also from what I can tell a scripted selection is only available to an FMEPackage transformer, not your run-of-the-mill Custom Transformer

Hi,

Have you tried using the conditional visibility option in the User Parameter section. 
With some work you can make the following: 

• A choice list parameter with all the database types you want to use
• A conditional visible Database Connection parameter based on you choice in the list of the previous parameter.

You could make something like this:
 

You can do the same for Web connections. This should also work in the Transformer designer as it uses the same parameter structure, but you will need to test that. 
As this is made in FME Workbench, it will also work in FME Flow products like Workspace apps.

Good luck!
