How do I create a segment to target specific users by their UserID?

Segments are built using Tags, which are key-value pairs assigned to users. A UserID is a unique identifier, but it is not a Tag by default and cannot be used directly in segment conditions.

To target users based on their UserID, you must first assign their UserID as a Tag value to their user profile. You can do this for one or more users by using the Update tags via CSV feature.

Steps to Assign UserIDs as Tags

1. Create a CSV file. The file should contain at least two columns: one for identifying the user (e.g., UserID) and another for the Tag you want to assign. For example, to create a Tag called user_identifier with the UserID as its value:

   UserID,user_identifier
   user-id-123,user-id-123
   user-id-456,user-id-456
   

2. Navigate to the import tool. In your Pushwoosh control panel, go to the "Update tags via CSV" section.

3. Upload and map your file. Upload your CSV file and map the columns to the corresponding fields.

   • Map your UserID column to the 'Device identifier'.
   • Map your user_identifier column to the 'user_identifier' Tag.

4. Start the import. Once the import is complete, the Tag will be assigned to the specified users.

5. Create your segment. You can now create a segment with the condition: "Tag user_identifier is user-id-123" to target that specific user.
