I have an existing flow that has a trigger `` For a selected file``(SharePoint). Basically, I run the flow by selecting a file from the SharePoint site and then select the proper flow that appears under the power automate tab and run it directly there.
My question is that How to call such a flow from power apps instead of SharePoint?

Hi @Serbay ,

Could you tell me:
Do you want to trigger the flow and execute it when you press a button control in the canvas?

If so , you could try to use instant flow.

I did a test for you:
1\ Add an instant flow and save it.

2\ Create a canvas app and add a button control.
Select this button and click 'Action' -> 'Power Automate'. Then add the flow.

Set the onselect property of the button control to:
TEST18.Run()

3\ Click F5 and click the button control to trigger the flow

4\ The result is as follows:

Hi. thank you for your answer. But I already have an instant flow that triggers by a selecting file from SharePoint. To run this flow through power apps, I need to attach/insert file by selection into power apps then once I click the button, I should be able to get the file and properties then.
As an example;

Hi @Serbay ,

I do not quite understand you.

If you want to use canvas to trigger an instant flow, you should choose powerapps trigger instead of for a selected file trigger.
Then you could not add for a selected file trigger after powerapps trigger.

If I understand it wrong, please show me the right direction.

Yes That's the problem actually, Once we run flow through the apps, we can not use the "For a selected file" trigger. So trigger has to be "Power Apps".
There needs to be such a way that, the flow should run depending on the selected or inserted file inside power apps.
For example; step1 - insert the file or write the path of the file into the text input
step2 - Then Run the flow from the button
The issue is how to run this flow for the inserted file?
Another Example to point the issue:
Let's assume we want to execute Script for a selected file through the power apps.
or let's say we want to add worksheet into an excel file through the apps for selected/specific file that has been defined from apps.
I hope you understand the issue now 🙂

Hi @Serbay ,

Sorry for the late reply.
According to your description, I think your needs can be met .

Firstly, you could create a gallery control and you could display these files in the control.
Secondly, Create an instant flow with get file properties action .(The Id of the action is passed from canvas)
Lastly, when the user selects a file in the gallery control, the Id parameter of the file is passed to the run() function of the button control, and finally pass to the the flow.
I did a test for you:
1\ Build my instant flow
Id : Ask in powerapps

2\ Add a gallery control and set its Items property to:
AABBCCDDEE
3\ Add a button control ,connect to the flow and set its onselect property to:
'PowerApp->Getfileproperties,Initializevariable'.Run(Gallery1.Selected.ID) // Gallery1 is the name of my gallery control .'PowerApp->Getfileproperties,Initializevariable' is the name of my flow

4/ The result is as follows:
Choose a file and click on the button to run the flow.

Successfully execute flow and get the file name property .
