A Node.js library and CLI tool that converts OpenAPI 3.0, 3.1, and Swagger 2.0 specifications into Postman Collection (v2) format. It can be used programmatically as a module or via the openapi2postmanv2 command-line interface.

Use cases

• convert openapi spec to postman collection
• generate postman collection from swagger json
• import openapi 3.0 yaml into postman
• sync existing postman collection with updated openapi spec
• automate api collection generation in ci pipeline
• validate openapi spec before conversion

When to choose

• you maintain API documentation in OpenAPI/Swagger and want Postman collections for testing
• you need programmatic conversion via a Node.js module
• you want to keep Postman collections in sync with spec changes
• you need a CLI tool for batch or CI-based spec conversion

When to avoid

• you need to convert Postman collections back to OpenAPI specs
• you work with API formats other than OpenAPI/Swagger
• you need a GUI-based import experience rather than a tool
