Dataflows in Dataverse, call refresh with variables as input parameters

[VictorShostak]

Hello,

Our issue is between Power Automate and Dataflow what is essentially Power Query.

We are working on an app to allow triggering refresh dataflows using variables as an input opposed to pre-selected Environment/Dataflow on Flow configuration.

It seems Power Automate Refresh a dataflow action accepts only IDs, not the names for Environments.

1. What is the suffix added to the Environment GUID "-31....-canada", where does it come from? can we query for it?

2. Dataflows are stored in msdyn_dataflows table, we can resolve Dataflow GUID by the name, however there are 2 records for each flow with the same name, one created by Developer and 

the other by #PdpfCDSClient. They are clearly different, IDs, the content.... but modified with 10 sec difference. Which record to select then? The latest?

Any ideas?
