How to send JSON data to Power Apps from Power Automate (MS Flow)

Question

I am getting the list Item attachments using the Get Attachments action in the flow.

As the output, I have the JSON object which contains the information of attachments.

Now, I want to send this JSON to the Power Apps.

Respond to Power Apps action allows us to send only single items, not objects.

How can I achieve the above?

Note: Please suggest a way which does not contain the use of a premium connector.

Answer 1

Solution 1 - Using Response action (Premium/Paid):

You can use Premium Response action to send complex data back to Power Apps from Power Automate.

Solution 2 - Respond to Power App action (Free but Complex):

You cannot directly pass JSON object to Power App from Power Automate. You can only pass String/Text value.

As a workaround you can send your JSON object to power app as a string by using a Join action in Power automate.

Then you need to parse that string to JSON using multiple Split functions and complex logic.

Check below link, it will help you to achieve what you want.
