![]() ![]() ![]() postman to develop and test the APIs on a daily basis, but the functionalities for teams and sharing the Postman documentation are paid, which makes it unfeasible to use in small projects or companies with limited budget, but at the same time maintaining two documentation bases is very laborious and can become unfeasible depending on the number of endpoints. THE OpenAPI has become a community standard for sharing RESTful APIs documentation, but I really like the tool.
