What is a UUID?
A UUID (Universally Unique Identifier) is a standard for uniquely identifying objects, users, sessions, or transactions. Version 4 (v4) is based on randomness, making it ideal for use in API requests, tracking IDs, or databases.
Why use UUID v4?
- Unique and random: virtually no chance of duplicates.
- Platform independent: usable in any system or programming language.
- No central coordination needed: no need to check a database for duplicates.
Use cases
- Identify API requests
- Track emails, ads, or users
- Sessions and tokens in web applications
- Logging and auditing
