I am continuously getting the following error (400 bad requests) while Sending a Push Notification using Microsoft Flow.

Same here---new to flow/powerapps (taking the Microsoft PowerApps course, in fact).

Here's what I get:

Hi @Sumitkhorana,

Before using the action Send push notification, have you created a connection to the app properly?

Please click the Connections, then create a connection to PowerApps notification with the proper URL or ID to the Target application.

Please check the following screenshot for a reference.

I have made a test on my side and it works fine.

Hope this doc on sending a notification from a flow could be your reference:

Yes, I tried using the URL and I tried using the AppID. Neither worked. I tried each twice, in fact. 4 failures.

Hi @v-yamao-msft,

I did the same steps and did those a number of times but I am still getting the same.  I then thought may be i am getting this error since I had selected the Asia region. I then created a trail for United States region and again got the same error.  I am not sure whats wrong though. Afterwards, I thought may be App ID isnt working then I gave the Power App complete URL but again got the same failures. I took the Web Link and App ID from Details section of the Power App. 

Many Thanks. 

Regards,

Sumit

I am not sure whats wrong but the connector started working without changing anything a couple of days later.
