Unique Identrifiers for API Operations
Operation IDs give each endpoint a unique, machine-readable name. SDKs, code generators, and documentation tools all depend on these being consistent and meaningful.
Operation ID Conventions
Operation IDs need consistent conventions because code generators, SDKs, and docs all use them. Inconsistent casing or characters here breaks downstream tooling in ways that are painful to debug.
