The Challenge

Imagine that Grab is introducing food delivery service in Philippines (like FoodPanda). You are tasked to design the driver app for motorbike drivers. Here is a rough outline of how the process is like:

API stands for Application programming interface. According to Wikipedia, it is a set of clearly defined methods of communication among various components. A good API makes it easier to develop a computer program by providing all the building blocks, which are then put together by the programmer.

If UI is for humans who interact with the face of a software, API is for programmers who interact with it behind the scenes to make the software functional.

Here’s what Jared Spool, a founding figure in design industry has to say about APIs in relation to designing screens.

As a designer, our primary role is to act as a bridge between users and stakeholders, providing necessary contexts, identifying core needs, and crafting best solutions to get the job done. …
