User IDs

You can assign your own user IDs to installations in WonderPush. This allows you to target users by user ID and lets you tightly integrate WonderPush with your systems.

Assigning your own user IDs

Assigning your own user IDs depends on the platform (adapt THIS_USER_ID) with your own user ID:

window.WonderPush = window.WonderPush || [];
WonderPush.push(['setUserId', "THIS_USER_ID"]);

WonderPush.setUserId("THIS_USER_ID")

[WonderPush setUserId:@"THIS_USER_ID"];

WonderPush.setUserId("THIS_USER_ID");

WonderPush.setUserId("THIS_USER_ID");

You only need to specify the userId once: it persists until next time you specify a userId or null.

Removing a user ID

User IDS can be disassociated from the current device Installation id using the Wonderpush SDK unsetUserId method. It is recommended to call this method when the user logs out of your app or website.

WonderPush.unsetUserId()

WonderPush.setUserId(null);

[WonderPush setUserId:nil];

WonderPush.setUserId(nil)

There are cases where the current user ID can change:

• when anonymous users log into your app / website, user ID goes from null to something,
• when the user logs in with another account.

When the user ID changes, a new installation is created. This means that all the tags, properties and events you've sent before changing the user ID will not be attached to the new installation. This ensures that data doesn't get mixed up between different user accounts.

Targeting users with the API

You can use the targetUserIds parameter of the Send notifications API call to target one or more users.

# Sending a notificaton to 2 users: userID1 and userID2 
# Adapt ACCESS_TOKEN
curl -XPOST https://management-api.wonderpush.com/v1/deliveries?accessToken=ACCESS_TOKEN -d notification='{"alert":{"text":"test"}}' -d targetUserIds=userID1,userID2

// Sending a notificaton to 2 users: userID1 and userID2
// Adapt WONDERPUSH_ACCESS_TOKEN, WONDERPUSH_APPLICATION_ID
$client = new \WonderPush\WonderPush(WONDERPUSH_ACCESS_TOKEN, WONDERPUSH_APPLICATION_ID);
$client->deliveries()->create(array(
    'notification' => array(
      'alert' => array(
        'text' => 'test',
      ),
    ),
    'targetUserIds' => ['userID1','userID2'],
  ));

Targeting users via the online dashboard

To target one or more users from the target tab of the notification edition interface, setup a criterion of type User id is equal to.
