Alias user (Segment)

Use this action to merge two identities in Segment. A common example is connecting an anonymous visitor to a signed-in user after login.

Add the action

1. In the WeWeb editor, open the Data & API tab, then open the Integrations subtab and add the Segment integration.
2. In an Interface workflow, click Add an action.
3. Select Interface → Segment → Alias user.
4. Select the Connection you want to use.

Configure the action

• Previous ID: The old identifier (often an anonymous ID).
• User ID: The new identifier (often your real user ID).

Advanced options

• Timestamp: When the alias happened.
• Context: Extra info about the environment.
• Integrations: Control which Segment destinations receive the event.
• Message ID: A unique ID to help avoid duplicates.

Common pitfalls

Aliasing in the wrong order

Make sure Previous ID is the identity you want to merge from, and User ID is the identity you want to keep going forward.
