When you are working with OpenAPIs within Postman it helps to be able to quickly pull that OpenAPI using the Postman API to then use for various stops along the API lifecycle. To help me better centralize and reuse requests across different collections I published a single collection that makes it easier to pull an OpenAPI for any API you are managing using the name of the API. The Postman API requires three separate API calls to be made before you get to the actual OpenAPI for the API, and this collection is meant to pull the OpenAPI by name with a single request.
You can view the documentation for this collection in the OpenAPI public workspace, where you can view the docs for the collection, fork and use the collection in your own work, while also commenting on the collection, providing feedback on where I should be taking it next. The collection documentation should provide you with all that you need to get started. If you have any questions that you don’t want to have listed in the comments feel free to email me at email@example.com and I will do my best to answer your questions.
