Agencies You Can Rely on for Your API Development Projects

In today's tech-driven world, APIs are dominating by serving as a vital link of data exchange between companies. Their mechanism of doing so ultimately frees up resources and streamlines operations. The beauty of APIs is that their benefits extend beyond the realm of tech companies - to small and midsize businesses as well! 

API development services is also one of the key aspects of the future of software development in Bangladesh. However, determining which APIs to develop and what products & solutions they will enable, require experience & expertise. So, in this blog, I will list down some of the API development companies based in Bangladesh and their services, participating in this digital transformation globally, for you to choose from based on your business transformation priorities, such as cost-efficiency, offshore development capabilities, or tailored digital solutions.


Before diving straight into the list, let us first break down the jargons we will come across in this blog –

  • API Development

    In simple words, API development is creating interfaces that allow different software systems to connect and interact with each other. 

    Think of a translator who helps different apps or software understand each other’s language. That’s basically what an API does. API development creates a pathway for seamless interaction, enabling applications to work together smoothly and exchange data, making operations more efficient.

  • Rest API

    One of the most popular APIs used by mobile and web applications to talk to the server is called REST API. REST stands for REpresentational State Transfer. 

    Imagine the Internet as a city and computers as its residents trying to talk to each other. In this scenario, REST API acts as the language that bridges the gap between computers. That is, it allows mobile and web applications to communicate seamlessly with their servers. Currently, REST is the most common API standard between computers over the Internet.

  • Simple Object Access Protocol (SOAP) API

    The Simple Object Access Protocol (SOAP) is like sending a message between you and your friend in a different language. In reality, SOAP APIs send information between applications in XML format.

    And the SOAP message consists of three elements – an envelope, body, and an optional header.

  • GraphQL

    GraphQL is an API query language and runtime. Think of it as a friendly mediator between your application and server. It allows the clients to ask for specific data they need and nothing extra. 

    With GraphQL, you can describe your API’s data clearly and make it easier to adapt and improve over time.


    JSON-RPC is a protocol that is used for data exchange between a user and a server. It uses JavaScript Object Notation (JSON) to encode data and messages, where the notes are written in a simple and easy-to-understand format. This helps both humans and computers to communicate effectively and exchange data smoothly. In simple words, a client can send a request to a server and the server can respond to that request with a response using JSON-RPC.

    XML-RPC works similarly but uses a different language called XML instead of JSON.

  • gRPC

    gRPC is an RPC framework developed by Google. It is like a super-fast phone line for computers. It is a modern and open-source framework using Protocol Buffers as the data format that supports multiple programming languages. This allows different services to talk to each other, no matter where they are. 

    It’s like connecting data centers with a special plug-and-play system, making communication between services efficient and reliable.
