Getting "command not found" for --http2, --header,and --data. I'm not sure what that's about. It also says "cure: no URL specified".

@drewpitchford, perhaps you need to update curl? What system are you using?

I recently added other features to this script but put it somewhere else: https://github.com/ben-xD/push/blob/main/tools/ios/send_ios_example You can send background and alert notifications to devices using this.

@ben-xD the latest version of macOS. I’ll see if there are any updates for curl.

I've created a tool to publish APNs to macOS and iOS (and Android) in https://github.com/ben-xD/push/tree/main/tool
