Re: Flow to powerapps

Hi @AVTS,

Flow doesn't allow you to add the respond to PowerApps in a loop. As far as I am aware it needs to be the last action.

I assume you want all responses from that HTTP action (which are parsed by the parse json action) in one result?

You might want to initialize a string variable at the beginning of your flow and add a append to string variable action at the end within the apply to each. This way you can use that variable in your Respond to action, avoiding that error you got earlier.

Re: Flow to powerapps

Hi expis.

I am unable to see any table details if flow action is placed as the last action of the flows . I mean outside of apply to each.

And i select with current item then while saving following error is appears.

Hi @AVTS,

Yes, a Respond to a PowerApp or flow action can be placed as the last action of your flow (outside of apply to each).

Re: Flow to powerapps

Thank you for your workaround,

This should be after parse json which will be outside of apply to each .Please assist,

Re: Flow to powerapps

Hi @AVTS,

Thanks for checking the output of the flow and sharing the screenshots. Good to know that the flow itself is outputting the correct values.

However, in those screenshots I can't see if you are using a Respond to PowerApps action within your flow?

Below is a example of that approach with that respond to action.

You could use a set variable in PowerApps and store the output of the flow run in there. You can use that variable in your label. This approach is described over here:

https://docs.microsoft.com/en-us/business-applications-release-notes/april18/microsoft-flow/return-data-powerapps

1. Set variable (VarResult) formula with output of flow run on a Button in PowerApps

2. Use the VarResult variable in a label in your Power Apps app.

3. In my example I have also created an output variable in my flow setup.

Hi @Expiscornovus thank you for responding.

Yes , Flow is responding proper output,

Is there anything i have missed here which is stopping power app to recognize the request?

Re: Flow to powerapps

Hi @AVTS,

Just to double check. Do you have a respond to PowerApps at the end of your flow and what type of fields are you using in there (text?).

Can you also share a screenshot of your flow run when triggering it from power apps. It completed successfully or did you have any errors?
