It is advisable to reflect aspects of using Postman or Insomnia in the API testing policy, where approaches to testing, collection structure, and automation scenarios are documented. It is also important to link with the API specification (for example, OpenAPI/Swagger), where endpoints, parameters, and data formats are described, and Postman collections can serve as a tool for validating implementation compliance with the specification. Both artifacts ensure transparency, reproducibility, and quality control of integrations.
