Here’s how you can use Environment Variables in your environment in Power Automate and Canvas Apps!

In case you are looking to create Environment Variables, here’s the post: Environment Variables in Power Apps and Power Automate

Power Automate

Here’s how you can use Environment Variables in a Flow –

1. You can’t use/access Environment Variables in a Flow which is not in a solution –
   Environment Variables are accessible in the Dynamic Content section on the very top of the list. [Since the below Flow is outside a Solution, you can’t see the Environment Variables]
   
   
2. Now, this Flow is within a Solution –
   
   
3. And then you access the Dynamic Content, you can see the Environment Variables.
   
   
4. And when you Run the Flow, the Environment Variable will show the value based on the Data Type set for the variable at appropriate places –
   

Canvas Apps

Unlike Power Automate Flow, Environment Variables in Canvas Apps can be utilized even if the Canvas App was created outside a solution –

1. In a Canvas App, click to Add Data Source.
   
   
2. On the Environment Variable Definitions/Values is added to the Canvas App as Data Sources, let’s take a simple Text control to read the Value from the Environment Variable used in the above Flow example –
   I’ll use Lookup() function in Power Automate to fetch the value of the Environment Variable by it’s Schema Name –
   Even if you only added Environment Variable Values table as Data Source, the Environment Variable Definition too will be added once you use the Lookup() function to fetch the value.
