Assuming you’ve encountered the term “API” while speaking with mobile app developers, today’s post will cover all there is to know about APIs, including what they are, how they developed, how to use them, how they function, and more with the So, buckle up and prepare to enter the world of APIs, the superheroes responsible for the operation of mobile apps.

Essential elements in API design

Here is a list of considerations an API developer should mind before and throughout API development. The development process will move more quickly and make it easier for the team to communicate effectively.

Security and Authorisation

Verifying the proper identification is the act of authentication. For instance, who has authenticated, is permit to access resources but not to create them. Some of the frequently used specifications for handling this authentication and authorisation are JWT, OAuth, and OAuth2.

Pagination, Query, Filter, Sorting

Your database will expand over time. When that occurs, you will notice that some resources are retrieving information more slowly than usual. Creating pagination filtering caching your objects are a few standard approaches to this situation. Sorting that data is delivered to the user one at a time by the request, modification, and condition. Paging is approach figuring out how frequently and how much needs to present. These factors guarantee quick response times, minimal processing times, and high levels of security with API development.


The user can retrieve resources incredibly quickly by using a cache approach. Your requests will be less expensive if your data is prepared to be used in an in-memory database. For this, you can make use of programmes like Memcached and Redis.


API wrappers are packages or containers that are particular to a language that aggregate groups of API requests into convenient functions. Multiple API integration calls are made the wrapper without the user’s involvement.


A component of the REST application architecture that stands out from majority other network application designs is called HATEOAS (Hypermedia as the Engine of Application State). Hypermedia refers to any content has links to media, such as photographs, text, and videos. A client can only communicate with a REST API using HATEOAS when the server provides dynamic replies.

This idea is similar to how web user navigates websites by clicking on hyperlinks to get where they want to go.

Error management

Debugging can be facilitated by effective error handling by determining whether a client or server error is to blame for the issue. The client may need to contact assistance for some problems, while others can be corrected by just changing the request. The following are some simple and effective error handling techniques:

  • the use of recognised standard error codes
  • supplying the appropriate number of mistakes
  • Defining the error’s root cause
  • identifying general and specific flaws
  • Validation

In APIs, validating data’s accuracy is known as validation. Client-side and server-side validation are the two forms of validation.

Client-side validation typically accomplished by providing quick feedback, such as flagging the incorrect entry in red or including a tooltip with correction instructions. The creation of API integration must include server-side validation. It entails certain menial chores like verifying whether a property is necessary, what kind of property it is (email, account number, etc.), or if a property is not necessary if another property is already there.
