Calling Flow in Power Apps: Google Books API

(2) ShareShare
ReportReport
Posted on by CU12091158-0 17
I have a flow I set up in Power Automate for my Power App that takes an ISBN number as it's input and makes a GET request to Google Books' API. The book information is stored in a variable in the Power App. This is what the flow looks like. 
 
When I test the flow using power automate, any ISBN I test with is passed to the HTTP request and I get the book information. When I try to run the power automate flow from the power app, the ISBN isn't passed to the HTTP request. 
 
Test with Power Automate
 
With Power Apps;
The number is obtained from the power app
 
but it's not passed to the ISBN. The field is blank when the request is made.
 
You get a result but just not the right one
 
The ISBN value isn't being passed to the HTTP request. Also, it's not because the data types are different (I ran a test to see whether it mattered although I can't see it among the many test flows I ran).

    So I figured out the problem with FLMike's answer as a nudge in the right direction. I had already put code within my Power App to convert the ISBN number into text. Even my variables list showed that my ISBN variable was text. But when it got passed to power automate, the "text" was still a number. I decided to instead take in a number in the power automate flow instead of text. And now it works.

    HI
     
    As you can see in one place you pass it as a Text, from the App you are passing it as an Number.
     
    You need to make sure from the App you are sending it as Text, not a number.

    Which formula did you use in your Power App? 
     
    And what is the reason you are using a response action and not the respond to a power app action?
     
    Below is an example how you could return a result.
     
    In the below fx the result is retrieved and stored in a Flowresult variable. The run uses the input from the TextInput1.
     
    Set(FlowResult, CallingFlowinPowerAppsGoogleBooksAPI.Run(TextInput1.Text).result)
