Is there a way to send a parameter value to a power app through a link?

[guyinazo]

I have created three smaller power apps that handles one bigger business process that we have.  The first application is an adminsitration application that people in HR will be using.  This kicks off a flow and part of that flow sends an email to the employee in question who will click on a link that will take them to the second application for them to complete.  

My question is, when the initial flow is kicked off, it creates a 'header' record in the SQL table using a unique ID.  So when the respondent goes in, they are using the generic application, but I also need that generic application to know that unique ID.  Is there a way to do that by perhaps appending ?<uid here> in the URL?  Or is there an easier way by doing perhaps a lookup to that table based on their Display Name (as I also capture their user info in that header file).

Thanks

Hello,

I don't think there's a way to send a parameter to the PowerApps application. Please note however that each application runs under a unique user (see User().Email). If you store the ID-User in your SQL Table then the user applications could extract the necessary ID on start. Hope that helps.

Yep, that is what I thought, but wanted to confirm.  OnStart I will do a Lookup to that database table to get that Unique test ID.

Thanks
