PowerApp with Custom Connector to Business Central



i have created an Office 365 Account E3 Trial, which has follow Products: 

Dynamics 365 Business Central for IW

MS Power Automate Free

Power Apps per user Plan Trial 

Power Bi Pro Trial 

Power Automate per user plan Trial 


I Created an Extension with Page Type API und published it in the BC Sandbox, then, in PowerApps i created Custom Connector, the Connector seems to work,  if i try Test i can receive Data  from a custom table created in BC, and i can save data in the BC Table. 


Now i would like to test this with a canvas app. 

Steps i followed: 

Create App -> Canvas -> i insert gallery, then select a source , i try MyCustomConnector, add a connection, then it ask me for credentials, i used the same as in the Custom Connector, (Web Access Key from the user in BC) , i click connect and then it says me: 


Premium. Apps that use this connector will require end users to have a power apps per app plan or power apps per user plan, then i click Got it, and then gives me an error: "There was a problem adding your service. please try again later

(Asyncronous operation 'AsyncLazy:AppHostPowerAppsClient._apiManagersById[apiId]' was cancelled. )


What can i do for try testing a canvas app with the custom connector to Business central? 


Thanks a lot

Re: PowerApp with Custom Connector to Business Central

Looks like I am alone with the problem 🙂


Maybe there is an overview somewhere of the requirements I need to create a PowerApp that connects directly to Business Central with a custom connector?


Is there a special license for development and testing? I understood that Power Apps Community Plan would be able to test and develop freely.


When I go to Plan(s) in the PowerApps Portal under Settings the following things are listed:

Power Apps for Dynamics 365
Power Apps Community
Power Apps for Office 365
