OpenAPI Tips - How to set operationId

The blog post discusses the importance of the operationId in the OpenAPI specification, emphasizing its role in API documentation and tooling. Although the operationId is technically optional, omitting it can hinder the generation of documentation, SDKs, and server stubs. The post recommends treating operationId as a required field, ensuring that each is unique, case-insensitive, and only uses alphanumeric characters with simple separators like hyphens and underscores. It highlights the benefits of this approach, such as avoiding naming conflicts, enhancing readability, and providing consistency within the OpenAPI spec. Examples of good and bad operationIds are provided to illustrate the importance of maintaining unique and clear identifiers to facilitate the generation of downstream artifacts.
