Amplitude User Mapping API
The Amplitude User Mapping (Aliasing) API allows developers to merge users with different user IDs together in Amplitude. This is useful when a user initially interacts with a product anonymously and later creates an account, or when users have multiple identifiers across different systems. The API maps these distinct identities into a single unified user profile to ensure accurate analytics and attribution.
