Documentation

UnionUser documentation: 5-minute quickstart, core concepts, five language guides, API reference and self-hosting.

5-minute quickstart From creating a product to the first activated device. Core concepts Products, plans, licenses, devices, seats and entitlements. Integration guides Java, JavaScript, Python, Rust and PHP. API reference Generated from OpenAPI and covering every public endpoint. Self-hosting Docker Compose, environment variables, backups and upgrades. Error codes Map errors to actions users understand.

Your installer carries a license key, not a secret

Every public licensing endpoint uses the customer’s license_key as the credential. There is no API secret to embed. The client only pins the public key used to verify signatures.

Suggested path

  1. Quickstart: get activation and offline verification working.
  2. Core concepts: token, exp, vun, entitlements and seats.
  3. Your language guide: the full loop and error handling.
  4. API reference and self-hosting: confirm the boundaries before launch.
