Is it possible to view Push Notification failures?

Hi there!

I recommend setting up Reporting Webhook for your workspace. Reporting Webhooks send real-time message activity events (e.g. sends, opens, clicks) as JSON in an HTTP POST. They’re useful in many cases, including analyzing message activity outside of Customer.io. More specifically, you can have reports of the event Push Failed, along with the relevant message data, and the failure message.

Here’s the Setup Guide to enabling webhooks as well, as all the types of events you can get reports of in the relevant documentation.
