Help How to do a Patch PowerApps and PowerAutomate?

[PabloRoldan]

I have an app that has some fields(Columns), and those columns i send them to a power automate flow... currently I'm doing like this

in power apps with
theFlow.Run(JSON({ "name":txt1.Text, "age":txt2.Text ... }))

the payload is like this

{

"name":"Jon",

"age":33,

"country":"MX"

}

but I'm sending all the JSON just for update a few porperties, let's say I only need to send "age" o just "country", and avoid sending all JSON payload, just the properties "that were updated" (SIMULATE like doing a PATCH) How to do that?

thanks

Hi @PabloRoldan 

We have only one option to know whether the form is UnSaved (IsDirty) not the field level. So the workaround is whenever data is changed collect those data in Collection.

Collect changed data on each Control update. For Example, Set the OnChange property of the Name (Text) control to

Collect(col_Items,{Name:TextInput.Text})

The system won't allow converting collection to JSON on the fly. So, convert it and store it in a variable "itemsJSON"

Set(itemsJSON, JSON( col_Items ));
theFlow.Run(itemsJSON);
Clear(col_Items);
