Re-explain
POST:
- Creates new resources
- Not idempotent (multiple calls create multiple resources)
- Server determines resource identifier
- Example:
POST /users creates a new user
PUT:
- Creates or updates resources
- Idempotent (multiple identical calls have same effect)
- Client provides resource identifier
- Example:
PUT /users/123 creates or updates user with ID 123
