What are Blockchain APIs?

An application programming interface (API) is simply defined as a special gateway through which software applications communicate.

Think of it as a side door leading to the kitchen, therefore, whether you enter the kitchen from the front door or the side door, you will have access to the pot of soup.

Technically, these APIs consist of a set of rules, routines and tools that, when embedded in other software, enable the systems to perform similar functions as well as exchange data where necessary.

APIs are used for the development of various applications, both web-based and mobile applications. It improves the development process as the developer only needs to focus on what differentiates the current application while using APIs to complement the common features.

There are various forms of APIs, Hardware APIs, Web APIs, Library APIs and Blockchain APIs among others.

Blockchain APIs are APIs that work specifically on blockchain platforms. It facilitates interactions between blockchain networks, in this way it is easier to develop blockchain applications based on these networks as developers mainly focus on the core functions of the application.

These can also be used in various contexts as long as it is run on blockchain technology, some APIs enable cryptocurrency exchange, supply chain management systems, digital asset management and so many other functions.

Blockchain APIs are very important in the development of blockchain platforms and applications, but before it is built into an application there are measures that must be taken to ensure that best practices are followed.

A thorough understanding of the functionality, limitations, and other capabilities or shortcomings of the API is strongly recommended.

This information should be properly reviewed before it is used in the development of an application.

Also ensure that standard protocols are used as this simplifies development as well
testing.

Examples of protocols that are often used are REST and JSON-RPC, these protocols make integration into other applications and platforms easier.

APIs can be quite slow and resource-intensive, so it is recommended to minimize latency and reduce server load by optimizing API calls. Caching, batching, requests, and data transfer optimization are ways to improve API calls.

Furthermore, security measures such as authentication, encryption, access control and other necessary functions should be implemented during the integration of these APIs as they provide access to sensitive data, to ensure that data breaches do not occur.

In addition to all of these best practices, monitoring the API to ensure that it is working efficiently and that there are no threats or security issues is essential. Various monitoring tools can be used to monitor API usage, one of which is the implementation of logging and analysis functions in the API.

Just like other APIs, there are different types of blockchain APIs that developers can use, including node APIs, data APIs, identity APIs, smart contract APIs, wallet APIs, and exchange APIs.

The choice of API to use is based on the function the developer wants it to perform in the application, and during selection compatibility, scalability, documentation and developer support should be considered.
