API Lifecycle, Part 1: Build and Test an API | Postman Intergalactic

Join us for a one-hour, intermediate-level Postman learning session geared specifically for API developers, API producers, and anyone else invested in building quality APIs. We’ll walk through the initial stages of the API lifecycle, including designing, defining, documenting, and testing an API.

Here's what we'll do in this session:
- Introduce the stages of the API lifecycle
- Review API-first model of software development
- Define foundational operations around an API including source control and collaboration
- Leverage Postman entities such as collections, environments, and mock servers
- Explore the industry-standard vocabulary of OpenAPI

Hi, I'm a Macbook user. When I try to create a new API, no configuration mode opens, it just creates 'New API' and then I have to manually enter everything, import the definition and create the collection from it. The user interface is different than the one shown here. There is no draft to rename, like in the video. I don't have the tests tab, in the version I have it's called 'scripts'... Am I doing something wrong or is this video already outdated?

The last step before you Import it the screen is totally different on my postman ( I can not choose to Link this collection as) I use postman for Linux version 10.22.3
Well thanks for the effort but this is an outdated video so not much help when the half of the UI looks totally different and can not follow on.
