Hi,

for the SimplePush we tag the different channels with a category, to give the "channelID" a "meaningful" name. That is also required when sending messages to different SP clients/channels (see [1]).

This would be useful on Android/iOS as well, for some sort of tagging/grouping (similar to the use-case in SimplePush).

Clients could specify a category, like:

...

[registration registerWithClientInfo:^(id<AGClientDeviceInformation> clientInfo) {

 

  clientInfo.deviceToken = deviceToken;

  ...

  clientInfo.category = @"something";

 

  } success:^() {

    ...

  } failure:^(NSError *error) {

    ..

  }

];

For sending push notification message to all clients, with the matching category, the "Selective Sender" API could have this field on its payload:

"category" : "something"

This would basically add the "category" behavior, used for SP to Android/iOS

Any thoughts ?
