Hi all, 

   I had used the one signal plugin to send push notifications.  Its showing an error of  "400 Bad Request".  And I had followed the following link. https://success.outsystems.com/Documentation/Development_FAQs/How_to_Use_Push_Notifications_with_OneSignal

Can you provide additional information?

You're saying that you followed the steps in the URL above, and you're getting an error?

Can you share your OML for the app that's not working?
