Hi @LG2 :
I've made a test for your reference:
1\Create a flow(Bof0328)

}
},
"statusCode": {

2\Add the flow into the app

3\Add a button and set it's OnSelelct property to:
Set(TheResult,'PowerAppV2->HTTP'.Run("61.768335,-158.808765"))
Click the button, the information of the area where the location is 61.768335,-158.808765 will be saved to the variable TheResult.
Best Regards,
Bof
