API has been richly adopted for mobile apps, putting mobile app developers on the go to continuously advance in their development skills.

Learning the peripherals of API development will set the foundation for a developer in the API development technology career. On this note, this article will embody the best practices and success tips for mastering API development by breaking down the essential basics of effective API development in technology that, includes what API development is, the features of API, examples of API, and categories of API.

Mastering API Development

What is API development?

API is standard in the technology industry, but what does it mean? Simply defined, API is a programming code that connects different applications.

It is the communication link between different mobile app software and applications. It also allows communication between systems and devices.

Application Programming Interface, API, is a set of software programming instructions and designs that allows two or more software applications, especially mobile app software, to share features that execute specific functions. Examples of this function are mobile game software applications, like Candy Crush, Project Makeover, Cooking Fever, and others that connect to the internet.

API works across many mobile application software; even Facebook and Instagram have the API development feature. These games have features for linking your game record and gaming account to a community of other games, especially on Facebook. This feature sometimes grants game users gifts for making the connection to Facebook.

Therefore, API development is the process of creating and maintaining API functions across various mobile app software. The development process of API explores designing the interface, encoding functions, and operations that should be carried out and identifying data formats and conventions for communication between systems. API development further includes testing and implementing the API, as well as documenting it for developers who intend to use it for future works.

Undoubtedly, API development is a critical aspect of modern software development because, with networking comes more connectivity, and API development enables interoperation between different software systems. It also facilitates the development of more complex and robust applications.

How does API work?

An API works according to the way it has been programmed to function. It starts with a user who sends a request to an API from their application. The API server receives the request and processes it according to the rules and protocols encoded in the API.

The API server then responds to the user application in a specified data format, such as XML. This response can be used by the user application to perform a specific task or retrieve data from the API.

Categories of APIs

APIs are categorized into different functionalities and purposes that many applications can’t do without. This is why mastering API development and understanding the different categories and their uses is essential for developers. These categories include:

  1. Partner API
  2. Internal API or Private API
  3. Open API or Public API
  4. Composite API

Partner API

A partner API is designed to enhance communication and interaction between two different organizations. It stands in as a third-party platform, providing a unified and integrated user experience. Partner APIs are common in the e-commerce industry, where the online market space relies on partner APIs to facilitate transactions and manage inventory across multiple suppliers.

Internal API or Private API

This category of API is explicitly used within a company or an organization. Seeing as it is not intended for public consumption, authentication and authorization is limited to only users within the company. It enables communication in a large company between teams, departments, or systems.

Open API or Public API

It is the API created and built for a more general audience. It is available to external developers and third-party organizations. There is no restriction or limitation for the users as it is accessible to users or developers that are interested in API development.

Composite API

Composite is helpful in situations where an API needs to access and deliver data from multiple sources in a unified and consistent interface to the user. It gathers data or functionality from multiple APIs, services, or data sources. Developers often use an API management platform or services that provide tools for integrating multiple APIs.

Types of API

Various types of APIs perform different functions. The type of API you choose depends on your specific purpose. These APIs include:

  1. RESTful API
  3. GraphQL API
  4. RPC API
  5. Web APIs
  6. Library APIs
  7. Cloud APIs
  8. Hardware APIs
  9. Database APIs
  10. Operating system APIs
  11. WebSockets
  12. Webhooks

Mastering API Development

Benefits of API Development

API does serve developers and development companies with so many benefits, but a few will be highlighted in this article. Developers who master API development get access to the following benefits:

  1. Efficiency
  2. Time-saving
  3. Integration and communication
  4. Flexibility
  5. Security
  6. Innovation


APIs improve development by allowing developers to reuse or advance their codes and functionality across different applications. It is efficient for all mobile app developers when they learn how APIs work through documentation.


Due to the API’s ability to enable developers to use its documented or saved data, developers do not need to design or build everything from the beginning. So, it doesn’t consume time when a software application or product is being built because it is not from scratch. The building of the application is based on existing protocols, and it also saves effort that can be used elsewhere.

Integration and Communication

API makes it easier to mix and induct various applications, products, and services with each other, thereby promoting communication and data sharing between software that is less complex. This benefit allows for ease in the flow of communication and access to more systems.


APIs have disposed of rigorous methods in developing app software. Developers are given the flexibility to choose whatever programming language and tool best suits their skills, experience, and tools. You can dabble between different choices of protocols and work at your set pace.


APIs provide a coded, controlled, protected, and secured way for systems and app software to communicate without the risk of data leakage or breaches. Despite its ability to share data, functionality, and connectivity, it applies high-level security encoded into its program. There is a static limit to what can be shared between systems and platforms.


It promotes a new creative drive by making it easy and less complex for developers to design or create new applications based on existing functionality. APIs birth new creations and fast tracks building of new products and works.

Tools for API Development

API development tools are vital to the building of software applications, and they include the following:

  1. Apigee: it is Google’s API development management tool. It helps when a developer is connecting apps.
  2. APIMatic and API Transformer:  these tools perform the same function of helping developers create and manage APIs, but they have different focuses, and that is, APImatic focuses on API design and documentation, while API transformer focuses on converting APIs from one format to another.
  3. API Science: This tool has the features of monitoring, testing, and analyzing API performance.
  4. Postman: It is an automatic interactive tool that allows developers to carry out the test on a document and evaluates the performances of their API.
  5. Swagger:  This tool is used by top technology giants, and it is used for developing APIs.
  6. Dredd: This is a testing framework that operates for HTTPS API. It checks if API responses match with API requests. It also checks for the alignment of API responses with documented responses.
  7. SoapUI:  It is an open-source testing tool. It is used to test API development across several platforms and systems.
  8. Sandbox: It provides an easy and quick test for API. It reduces the cost and associated possible risk with bringing in a third party during thorough testing.

Terminologies of API development

To claim the master level in API development, there are some registered terminologies that you should use and be familiar with as an advanced developer. Some of them include:

  1. Rate limiting: It is the number of times a user sends requests to API.
  2. OAuth: It is an open standard authorization for APIs.
  3. API throttling: It refers to the process of controlling how users make use of API in a specific period.
  4. POST: It is a method used to send data to the API server to create a source.
  5. API key: It is a unique key identifier or code passed to authenticate the user calling program.
  6. Request: It is an HTTP message sent by a user to the server to receive data or information in return
  7. Response: It is an HTTP message the server sends to the user as a response.
  8. GET: It is the technique used to request data from a server.
  9. Latency: This is the time taken and spent by the API to process a request.
  10. JSON:  It is an acronym for JavaScript Object Notion. It interchanges data on the web.
  11. Endpoint: The meeting point between API and server.
  12. REST: It stands for Representational State Transfer. It is a program meant to enhance the efficiency of communication and connectivity between two systems or devices.
  13. SOAP: Simple Object Access Protocol shares structured and organized information about web services in computer networks.
  14. Payload: It is the data transmitted in the body of an HTTP request or response.
  15. Status code: This is a 3-digit number displayed in return by the server for a failed request. 404 Not Found and 500 Internal Server Error are the common status code often displayed to users.

Best Practices for API

You can design and create APIs that are easy to use, giving value to your users and paving your way in the industry by using these best practices for API.

  1. Error handling
  2. Use throttling
  3. Use consistent naming conventions
  4. Consider your API gateway as Enforcer
  5. Use standard protocols

Error handling

APIs should handle errors carefully and unnoticeably. It should be programmed so that the moment an error is detected and corrected, it should return an error message to the user. This message should be clear and concise.

It should also include helpful information and insights into the error and how the problem can be resolved. Information like that will help you solve the problem quickly.

Use throttling

It is a good practice for redirecting the overflow of traffic to avoid a crash in the server. It limits and controls the rate at which users can request at a time to an API. It majorly protects the server from getting overcrowded and overloaded.

Use consistent naming conventions

The use of the same name repeatedly and consistently in API makes it easy for developers to understand and find their way around it. It is one of the best practices to use clear, descriptive, and identifiable names for API endpoints, parameters, and responses.

Consider your API gateway as Enforcer

API gateway enforcer implements the policies and rules guiding API traffic. It typically includes security policies, such as authorization and throttling. API gateway acts as the intermediary enforcing the protocols of API development policies.

Use standard protocols

Standard protocols like HTTP, JSON, and OAuth make it easier to integrate APIs into different applications. That is, these protocols bring ease in creating and inputting APIs in various developing software. Using this best practice gives room for ease in sharing and reusing API.

Tips to Master API Development

Developers can master API development by committing to some steps and procedures. With these tips below, you can build powerful and effective APIs that match users’ needs.

  1. Have the basic technical know-how
  2. Document your API
  3. Choose the right tools
  4. Design API carefully
  5. Test rigorously
  6. Be updated on the latest trends
  7. Keep practicing

Have the basic technical know-how

This is one of the foundational pillars of becoming an API development guru. As a developer, you should be equipped with at least the basic knowledge and skills to build an API. It is from this technical know-how that you can come up with creative innovations even if they are still in the ideation stage.

You do not need to bother about getting to the expert stage at the very beginning. Start by learning the basics of APIs, including their purposes, uses, and functionality. Familiarize yourself with anything and everything API development.

Document your API

You don’t become a master without knowing the conscious, intentional, or unintentional steps or procedures you took to build your API. It is, therefore, vital that you store and record everything you did in building your API. This way, you can review your procedures again, learning and improving through your experience.

This also extends to help novices and other developers whenever they want to build software based on your developed API. It should be comprehensive, thorough, and transparent with information on its purposes and functionality.

Choose the right tools

You can never be too careful when choosing the right tools for building APIs because you have to ensure you pick tools that are easy and relatable to you to enhance a better work and product. Select the programming language framework that best suits your needs, innovations, and development. Do well to also consider factors such as performance, ease of use, etc.

Design your API carefully

While you are out there building what has been born out of your creativity, you have to have it at the back of your mind that other developers would have access to this, and so your work shouldn’t be a flop. For this reason, ensure to design your API carefully without errors or glitches. It will be a recommendation of your work and a guide to others interested in API development.

Take the time to design your API carefully, including defining the end product, the methods, security measures, data structures, and formats. Endeavor to use best practices such as versioning, documentation, throttling, error handling, etc.

Test rigorously

An API is never ready until it has a 100% pass of working and functioning as it is meant to. While testing, do it with scrutiny and leave no mistakes out. Make it your pain point to sight out errors and glitches.

This is critical in ensuring that your building API functions correctly and rightly with no malfunctions. You can test your API thoroughly using automated testing tools, and you can use Postman or Insomnia for manual testing, whichever you trust best.

Be updated on the latest trends

Daily, innovations keep advancing, and the technology industry or space is not left out, as most new trends start with them. To keep up with building the API users need and can constantly relate to without finding so much complexity, you must master the art of learning new things and keeping up with new trends.

Stay updated with new tools, best practices, protocols, and API development from other development companies. To do this, you can attend conventions, and conferences, read articles, brochures, and blog posts, and be a part of online communities.

Avoid getting archaic with advancements in every sector. Creativity can spark from anything new or redeveloped. You have to keep updated with new creativity to design great APIs.

Keep practicing

No one ever gets better and becomes a master without consistency and devoted practice at what they do. This also applies to API development; just like every other thing, it also needs time and commitment to make a score with it. One becomes a master with repeated experience, and for it to happen, you have to commit yourself to work on your API development repeatedly.

Therefore, work on small projects, volunteer for internship programs in API development Companies, and contribute to open-source projects. Keep your eye on the main focus of becoming a master at API development.
