Here are 3 simple components for a great API:
Multiple Formats: Distinct applications speak distinct languages, comprising JSON, XML, and CSV.
Documentation: It is a no-brainer. Without API documentation, no one would be able to use the API. API Documentation is the beginning point toward making it DevOps friendly.
Community: Developers search for a helping hand from other developers. The majority of them have widely adopted APIs and are backed by robust developer communities.
