What is User ID?
You can set a unique user ID used in the app.
The user ID which can be set is a character string that can identify the user such as the member ID for the service.
Identification of users
By setting up a fixed user ID, session data coming from different devices can be considered the same user information, even if the end user has multiple devices
Setting a fixed user ID enables you to deliver the Push Notification by specifying the user ID from the server of your own app, without using the Repro dashboard.
For details on how to deliver Push Notifications through the server of your app, please check delivering via API.
Import of user list
Importing a fixed user ID into Repro from your own app's server enables you to send Push Notifications and In-app messages.
Please check Creating a New Audience for the details on How to import audiences.
Settings of User ID
Please check the development guide for the details on how to implement.
- If you set a string that is likely to be duplicated such as Name, it will be regarded as that the same user has multiple devices.
- If the user ID is changed in the middle, it will be regarded as a new user holding the device. Therefore, the previous action history and User Profile will not be taken over.
- Please do not set a user ID for users who haven’t logged in yet. The action history and User Profile,, which are recorded when the user ID, is not set will be inherited even after the user ID is set. However, if the user ID is explicitly specified before login, the action history and User Profile before and after login will be treated as different users.
