Benefits Of Using Our API Development Services

We take pride in being one of the best API developers in India. Our feature-packed programs are regular market winners. The benefits of taking our API development services include:

Better System Scalability

Using API allows different system parts to be scaled up (or down) without affecting the rest of the system. With API, you can add new servers without changing your website code. The API will communicate with the new servers to improve the scalability without impacting performance or reliability.

Flexible System Updates

API is a set of software tools and protocols that allow developers to interact with an application or system. APIs also allow for flexible system updates, allowing developers to add new features and capabilities without disrupting the system.

Faster Marketability

An API can be used to create a marketplace where buyers and sellers can connect more easily. It can also create integrations between different platforms, making it easier for users to move data back and forth between them.

Lower Development Cost

Using an API, you can abstract away the underlying implementation details of a service or piece of functionality and simply focus on sending and receiving data. This can make developing applications that interact with complex systems much easier, faster, and more cost-effective.

Better Developer Experience

API usage allows for a better experience for developers as they can easily access the functionality of other software programs. Additionally, using an API allows developers to spend less time coding and more time developing new features and functionality.

Fault Tolerant System

API allows different software components to interact with each other. It also allows for systems to be more fault-tolerant and highly available. With fault tolerance, a system can continue functioning even in failure. API allows different components to communicate and share information about the system.

Ultimate User Guide To Understand API Development

What is API Development?

API Development is the process by which an application requests one or more other applications and services, usually over the internet, to get specific data or functionality.

The term “API” is short for “Application Programming Interface” and refers to the various means that a developer has of communicating with other applications and services. APIs can ‌request data from outside sources or  ‌issue commands or instructions to other applications.

API development usually involves using special software development tools known as “API frameworks”. These frameworks provide a simplified means of communicating with other applications and services, reducing the amount of coding required.

What are the steps of developing an API?

There are various steps involved in developing an API, but the most important ones are‌:

  •  Planning and designing the API: This includes defining the functionality and structure of the API, as well as how it will work internally.
  • Implementing the API: This is the actual coding process, where you write all the code for the API according to your design plans.
  • Testing the API: Once the code is written, it needs to be thoroughly tested to make sure it works correctly and meets all requirements.
  • Documentation and release: Once everything is working as it should, you need to create documentation for users so they know how to use your API correctly. After that, you can finally release your API.

What are the different types of APIs?

There are many types of APIs, but we can broadly classify them into four major categories: SOAP, REST, HTTP, and WebSocket.

SOAP (Simple Object Access Protocol) – It is a standardized protocol for building web services. It uses XML to encode messages and relies on transport protocols like HTTP or SMTP for message passing. SOAP is widely used in enterprise applications because we can easily integrate it with existing systems, and it provides a robust way to implement web services.

REST (Representational State Transfer) – It is an architectural style for building web services that uses simple HTTP requests to make direct calls to resources without going through a central dispatcher. This makes RESTful applications much simpler to develop and easier to scale than other applications.

HTTP (Hypertext Transfer Protocol) – It is the most common type of API. It’s used to exchange data between a server and a client, usually HTML pages. HTTP is a stateless protocol, meaning each request is independent of all other requests making it inefficient for exchanging data between a server and multiple clients. So, it’s not typically used for real-time applications.

Websocket is a newer protocol that allows browsers to communicate with servers in real time. It’s more efficient than HTTP because it uses sockets to directly connect the browser and server.

What are the key features of an efficient API?

Any API is considered efficient if it performs its function with a minimum amount of computational resources and latency. In terms of resource utilization, an efficient API will use the smallest possible memory footprint and CPU usage. It will also minimize network calls, making batch requests when possible.

In terms of latency, an efficient API will have quick response times so that clients don’t have to wait long for data. It will also utilize caching to reduce the need to fetch data from the origin server. Cache invalidation strategies should be carefully implemented to avoid stale data.

Security is another crucial consideration for any API. An efficient API will have well-designed authentication and authorization mechanisms to keep data safe.

Project Based

(best suited for small-mid scale projects)
Fixed Price Model:

When project specifications, scope, deliverables and acceptance criteria are clearly defined, we can evaluate and offer a fixed quote for the project. This is mostly suitable for small-mid scale projects with well documented specifications.

Time & Material Model:

Suitable for projects that have undefined or dynamic scope requirements or complicated business requirements due to which the cost estimation is not possible. Therefore, developers can be hired per their time.

How much do you charge to develop a custom API?

The average cost of developing a custom API can range from $15 to $30 per hour, depending on the project’s complexity. To get an accurate quote for your project, it’s best to consult a professional development team who can assess your specific needs and give you a price estimate.

When considering the cost of developing a custom API, it’s essential to keep in mind the ongoing maintenance and support expenses associated with it. These costs can add up over time, so it’s important to factor them into your budget when deciding whether or not to develop a custom API.

What technologies do you use for API development?

When it comes to API development, there are a few different technologies that we use to make the process more efficient and streamlined. 

One of the most popular technologies for API development that we use is REST, or Representational State Transfer. This type of architecture enables simple, fast, and scalable APIs that are easy to develop and maintain. 

Another common technology we use for API development is SOAP or Simple Object Access Protocol. This ensures a standard way for different applications to communicate with each other using XML.

Finally, another popular technology used for API development is known as gRPC or Google RPC. We use it for its high performance, thanks to its efficient binary encoding and language-independent nature. 

How do you handle API versioning and updates?

API versioning and updates are critical to ensure the stability and reliability of APIs. We use industry-standard version control systems and follow best practices for API versioning and updates. Our team closely monitors changes in technology and the needs of our clients to ensure that our APIs are always up-to-date and compatible with the latest systems. We also provide documentation and support for developers to make the transition to new API versions as smooth as possible.
