Introduction to Postman to Swagger OpenAPI

The Postman to Swagger OpenAPI is a specialized tool designed for converting Postman collections, which are JSON exports containing API request and response definitions, into Swagger YAML files compliant with the OpenAPI 3 standard. This conversion facilitates a smooth transition between API testing in Postman and API documentation or client SDK generation using Swagger tools. An example scenario where this tool is essential involves a development team that begins API testing with Postman due to its user-friendly interface and later decides to use Swagger for its comprehensive documentation capabilities and wide support for automated SDK generation. The tool autonomously identifies endpoints, parameters, request methods, and responses within the Postman collection and meticulously formats them into a structured Swagger YAML document, adhering strictly to the OpenAPI 3 syntax and standards.
