Notifications in Odnoklassniki

You can send notifications to users in Odnoklassniki — messages that remind them about the app, help retain active users, and bring back those who haven’t opened the app in a while.

To send notifications, use the OK API methods:

• •
  notifications.sendSimple — to send a notification to a single user by their ID.
• •
  notifications.sendList — to send an array of notifications to different users by their IDs in a single request.
• •
  notifications.sendMass — to send a notification to app users whose profiles match the specified criteria.

For more information about working with the OK API, see Server-side API calls.
