Pass Text Input Values from PowerApps to Flow

[huffmaster]

Hi All - 

I'm trying to determine the best way to pass the values from 10 or more text inputs in a Power App to a Flow.  There's no data source in the power app so I'm not using a Form of any kind, I'm just using text inputs.  I've seen the examples where others attach a Flow to a button and use the MyFlow.Run command but I don't see how I would pass all the values from my app to the flow.  Is there some collection of all my text inputs I'm not aware of that I can pass as a parameter or do I have to build a collection on the power app side to pass through to have my flow see all the separate values?  Thanks for any help you can provide.

Thx for the help Reza.  The post seems helpful but it's not clear at all as to how I pass or access the JSON once I've set it in the power app.  The author early on writes...

I’m starting by creating a single input in my Flow. My input is called Compose_inputs, but you could call it anything you like.

 There's nothing else in the post to indicate what Compose_inputs is, or where it's set, or where it comes from.  It's very confusing.  When testing the flow I'm not prompted for any type of input so I'm still not sure how I'm supposed get the JSON I've now created in my power app inside the flow.

I ended up working through the issues I was having.  Inputs need to be a lot more clearly defined in Power Automate, it's not intuitive at all, and I still don't understand how you would ever remove inputs. 

Thx again for your help @RezaDorrani.

why is this marked as solved when, indeed, the explanation greatly lacks of detail.

What is "Compose_inputs"? Can you give more details.

This is late, but referring to the link RezaDorrani posted:

- Create an Instant Cloud Flow and choose PowerApps as the trigger

- Create a Compose element and in the input field, select "Ask in PowerApps" under Dynamic content. A 'Compose_input' object will appear in the input field. Now remove the 'Compose_input' from the input field.

- Now click the Expression tab and type json(), then click between the parentheses and click the Dynamic content tab, then select "Compose_inputs" and click Ok.

- Save the Flow

Go back to the PowerApp, add a button and in the OnSelect field insert (example):

Set (toJSON,
"{
'field1CanBeNamedWhateverYouNeed': '"& TextInput1.Text &"',
'field2': { 'field3YouCanNestJsonElements': '"& TextInput2.Text &"' },
'field4': {'field5AnotherNesting': '"& TextInput3.Text &"'}
}"
); NameOfYourFlow.Run(toJSON)

As you can see, 'Compose_inputs' is just a dynamic variable that is used to receive the data from the PowerApp by the Flow.

NameOfYourFlow.Run(toJSON)

am getting an error in the above line saying that: invalid number of arguments: received 1, expected 0

Better explanation

PowerApps - Send your data to Microsoft Flow with less parameters (sharepains.com)

OBS: To connect your flow to the App you must go to the left menu and click "Power Automate". Here you click "+ Add Flow". Selct the fow.
