Prototyping an API integration with a UI

At this point, your API design has been validated, and you’re ready to implement it. Almost. Before that, I want to show you that you’re still missing one type of validation that might reveal that the API design still needs to be refined. By creating a prototype of API integration with a UI, you’re able to put it in front of non-technical users to understand how they interact with it. I’m going to show you different tools and techniques to create UI prototypes that can connect to your API mock and interact with it. Let’s start with an easy approach that doesn’t require any code and uses a tool that lets anyone build web applications. Retool is a popular web application creation tool that can connect to an external API that uses the JSON response data format. With this combination, you can put together a visual UI that loads data from your API mock. The second approach uses Postman and one of its features...
