Understanding UX Driven API Designs In 2022 - A Complete Guide

Most software developers assume that writing code is a private relationship between them and their computers. Well, this is wrong because code is not only meant to be read by computers but also by human beings.

As a developer, you need to understand that you will have other people and developers reading, building upon, and maintaining your code. This means that no matter what you are developing, you should think about the experience these people go through when using your code.

This is where user experience (UX) comes in. It should be a part of your API (Applications Programming Interface) design. An API that is well designed with an outstanding user experience will solve more problems than a complicated API with hundreds of functionalities.

But why do some developers ignore UX when designing their APIs?

Here are some of the common reasons for this;

Assumptions by Developers

Some API developers assume that their API users have enough knowledge and context to understand how APIs work because they themselves do. Unfortunately, most end users understand very little when it comes to APIs compared to the API developers.

In addition, API developers complicate the designs of their APIs because they have been in the field for a long time and they have handled many complex APIs before. This is wrong because a bigger percentage of your API users might not be able to handle complex APIs.

When designing an API, you need to think about the end users and the kind of limitations that they might have. You also need to make sure that everything is simple, from the design to the implementation even for a person who has never dealt with APIs before.

Distance from Users

Most API designers and developers spend a lot of time behind closed doors working on their APIs. During this stage, they mostly do not interact with other people, especially future API users who are very critical to the success of an API.

Developers avoid thinking about future users because they assume that they would be creating an abstraction if they did. This is wrong and is one of the leading factors for APIs with poor user experience.

Fortunately, when these developers spend time with API users and see how much they struggle using and implementing the API, they understand the things they should consider to enhance UX. Very few API developers ever do this.

Use of Poor Tools

Software development is not a walk in the park. Designing and building an API that works is not easy either, and shows how good a developer is. This makes some developers stick with poor or hostile tools because they feel good cracking the difficulty with these tools.

However, no matter how good you are, you will need users for your API to be successful. This does not apply to those who build APIs for their own internal use. If users struggle to consume your API due to poor UX, then the API is bound to fail.

UX Driven API Design - Guide

Even though API design is not a walk in the park, it is also not complicated. All that API developers need to do is follow some basic rules. All these rules revolve around thinking about the end users and their experience.

Your end users are not just smart developers like yourself or experts in API design and implementation. You should ensure that all users, including first-time API users, are taken care of. They should all be able to use your API without any problems. This can be achieved by following UX tips and strategies to improve your user experience.

Here are a few rules to follow for UX-driven API design;

Provide Feedback

One of the things you need to keep in mind when developing UX-driven API designs is how interactive your API is. Users should find it easy to use your API without necessarily depending exclusively on tutorials and the API documentation.

For instance, they should be able to try things that look intuitive. When they do, the API should provide them with feedback that they can act upon. For this to work, you need to catch all user errors early enough and understand some of the most common mistakes from users.

In addition, input validation should be performed in the early stages before users start deep interactions with your API. You can also track common mistakes from users and use them to make your API even better. You can also create a page where they can get solutions to some of these mistakes.

Building a UX-driven API also requires you to create a platform where users can ask questions or criticize the API. This will help you understand the pain points of your API, something that you need in making the API better.

Reduce User Cognitive Load

You need to make all API processes and workflows as easy as you can to reduce user cognitive load. This is the effort, especially mental effort, that users have to invest in in a bid to understand how your processes or workflows actually work.

If a user wants to integrate apps (via APIs), for instance, then you should require less focus and effort from the user. This will give that user more time to effectively use your API in solving their own problems. If not, they will spend more time figuring out how to integrate apps or when to use different methods in your API.integrate apps (via APIs)

You can achieve this by using consistent code and naming patterns, introducing few or limited new concepts, using effective API documentation, and automating processes that can be automated, among others.

To measure this, get a new API user and ask them to go through an API workflow for a certain problem using your tutorials or documentation. Wait until a day later and then ask them to solve a similar problem using the same workflow. If they cannot do this without looking at the tutorials or documentation, then there is a problem.

Design User Workflows

One common mistake most developers commit is focusing more on atomic methods instead of holistic workflows. This means that API users are left on their own when it comes to understanding the API's workflows.

This leads to a poor user experience that is synonymous with hacks and long routes going through technical challenges. Fortunately, UX-driven API design helps developers avoid this and make things easy for their users.

The first step in solving this problem is understanding all the workflows, especially the common ones, that the API will deal with. This should also include the use cases your users will want more. You should then go through these workflows or let a new user do it on their own. This allows you to identify any issues and then solve them to improve the user experience of your API.

APIs are driving digitization in businesses around the world. Their usage is going to keep on growing, making it necessary for developers to build UX-driven API designs. This makes things easy for their users.
