Push by User ID

User-centric push notifications

This method allows you to send targeted push notifications to your users across their multiple devices. Resulting push notifications will be delivered to all devices associated with a specified User ID.

Collecting User IDs

Call setUserId with the first app launch or in case your User ID has changed. User ID could be a user identifier that you keep in your own database.

Example (iOS, Android):

(void)setUserId:(NSString *)userId
public void setUserId(java.lang.String userId)

Login/Logout behavior

By default, when an app with Pushwoosh SDK is launched for the first time, it sets a device HWID as a UserID. You can call setUserId on a login to set any required value to associate a device with a particular user. When a user logs out, you can reset this value to a default one with another setUserId call, e.g. to an initial HWID value.

Sending a push by User ID

To send a push to a list of users, you can either use /createMessage API call, or upload a CSV file with the User ID's.


Please note that /createMessage parameters are fully customizable, so you can create a highly tailored push message. Check the full list of parameters here.


	"request": {
		"application": "APPLICATION_CODE",
		"auth": "API_ACCESS_TOKEN",
		"notifications": [{
			"send_date": "now",
			"content": "Hello world!",


   "response": {
      "Messages":["{Notification code}"]




Your Pushwoosh application ID where you send the message to (cannot be used together with “applications_group”).


API access token from the Pushwoosh control panel (create this token at https://cp.pushwoosh.com/api_access).


Set the time you want the message to be sent (in UTC) or use ‘now’ to send it immediately.


The text for your push notification.


A list of User IDs your push message is sent to. You can send a push to a 1000 User IDs at once.
