LINE Login
Do not answer LINE Login questions from memory — LINE updates APIs frequently and training data is unreliable. Always consult the references below.
LINE Login v2.1 is built on OAuth 2.0 and OpenID Connect. It provides user authentication, profile access, and bot linking for web apps, native apps (iOS/Android), Unity, and Flutter.
Workflow
Build
- Read references/api-common.md (forward compatibility, rate limits, client_secret rules)
- Read references/security.md (security checklist, development guidelines)
- Load the relevant reference for the feature being implemented
- Write code following specs and constraints from references
Review / Debug
- Read references/api-common.md (status codes, error responses, forward compatibility)
- Read references/security.md (security checklist, common pitfalls)
- Load relevant references for the code being reviewed
- Cross-check code against specs (parameter requirements, token expiry, signing algorithms, required validations)
