I'll assume it's the latter. Mocks are quick apis you can set up (mockable.io is a popular one) in a couple minutes that can be configured to provide an endpoint and a static response that you tell it to. Using that, you can hit the mock endpoint with your front end code. If you do it right and make a constant, and collaborate on the endpoint and object with the BE dev, the only thing you'll have to change when... Source: almost 3 years ago

As for the actual process of building the contract, what works well for me is using API Blueprint-style Markdown in a compatible tool like Apiary, which renders your content into Swagger-like documentation as you type. This way, I and others can mutually "live-scribe" the API contract as we discuss, and seeing it on-screen helps to get people on the same page (and sometimes highlight potential issues that would...

The problem with many of these alternatives is that in most cases they aren’t really more readable or easier to learn. Simpler description languages also tend to support less capabilities for documenting API features.... - Source: dev.to / almost 2 years ago

For the context of this post, only the first task is essential. In it, the team works together to define the API contract. They discuss data format, whether the API will be Rest or RPC, authentication, data compression, and other vital issues. The delivery of this task is the documentation, preferably in a standard like OpenAPI or API Blueprint (my preferred format). - Source: dev.to / almost 2 years ago
