Creating a modern software product does not always involve designing and writing its functions from scratch. Fortunately, the last decade of active digitalization of business processes and services makes it possible to effectively use various existing software solutions and combine them to solve new problems. This article focuses on API integration opportunities in software development and how it can help your business improve its software while avoiding large-scale expenses.
What is an API Integration
API integration is a wonderful software development life hack that allows you to quickly deploy complex information systems with relatively low costs for their creation.
Just think how profitable it is to link and synchronize the work of already existing, proven, and effective products without spending time and money on programming their counterparts. Indeed, with the help of APIs, you can create a multi-level and targeted routing of data from various existing sources, services, and applications to meet the business’s internal administrative objections and its customers’ needs.
So, what is an API integration? In the most common sense, it refers to connecting two or more separate software applications through their respective APIs, allowing them to communicate and share data expanding the range of useful functions of the developing software product.
The most common API integrations are custom ones created by developers based on the technical specification of a particular project, connector applications in a box, and cloud API integration platforms available on the market. Each type has its pros and cons; however, developing a custom one, as performed in the video presentation instances below, allows you to fully unlock the potential of the software product in achieving current business goals.
How do API Integrations work
Application programming interfaces are software intermediaries allowing different applications to talk to each other. On the one hand, the API is a tool that helps the servers fulfill the user’s requests. Still, on the other hand, it’s also responsible for translating those requests into formats the servers of commutated systems can understand and respond to with the relevant data.
Here is an example scenario, answering the question of how does API integration work:
- A user asks a primary application for data provided from another app.
- The first application requests the data from the second through API.
- The second application receives the request, authenticates it, and retrieves the appropriate data from the app’s database.
- The second application sends through the API the retrieved data back to the first one.
- The primary application receives the data, processes it, and displays it to the user.
This process happens in real-time. Therefore, to get a stable workflow, developers must ensure that the API integration is secure, reliable, and efficient.

How to build API Integrations
Building API integrations requires specific skills, including knowledge of programming languages like JavaScript, Python, or Java, certification methods, and data exchange protocols. The process itself usually involves:
- Exploring the API documentation;
- Authentication setting;
- Developing the integration solution;
- Testing and debugging;
- Further maintenance.
1. Exploration of the API documentation
API documentation is the foundation for any integration process because it outlines the available endpoints and methods for a given API. This description provides all the necessary information to understand the API’s structure, required authentication, general parameters, and expected responses.
Exploration of the API spec includes:
- reading the API documentation;
- analyzing the examples provided in the documentation;
- checking the data formats that are accepted and returned by the API;
- investigation of the available URLs that the API uses to access certain data or functionality and specific actions like retrieving, updating, or deleting data that can be performed there.
It should be reviewed thoroughly to understand the API’s purpose and how it fits into the project’s goals.
2. Authenticate with the APIs
Authentication is verifying the identity of the user or application making the API request to ensure that only authorized users or applications can access the API resources. This step is critical because APIs often provide access to sensitive data. Failure to properly authenticate with an API can result in unauthorized access to confidential data or other security breaches. That’s why developers follow the guidelines provided by the API provider to establish correct confirmation practices in the application when integrating a new API.
These guidelines typically include information on the type of proof required (such as OAuth, API keys, or tokens), how to generate and store certification credentials securely, and how to handle errors. Developers may also use authentication libraries or frameworks to simplify the verification process and reduce the risk of security vulnerabilities. Additionally, developers test the validation process thoroughly to ensure it works as expected and identify and address any potential security issues.
3. Build the integration solution
To build the integration solution, developers must first choose a programming language and development framework. They then write the code allowing the software to communicate with the API using the available endpoints and methods.
In many cases, developers create a basic prototype of the integration solution to test the functionality and identify potential issues. It can be helpful to catch any errors early in the development process and make adjustments as needed before proceeding with the full implementation of the integration.
During the development process, ensuring that the integration solution is robust and scalable and can handle large amounts of data and traffic is crucial.
4. Test the integration and handle errors
After the integration solution is built, the next step is to test it to ensure it works as expected. This process involves running various test cases to be sure the integration solution functions correctly in different scenarios. Developers must consider different data types and input values the API connection might encounter and possible error conditions.
During the testing phase, testing error handling is essential to ensure the solution can function in unexpected conditions and errors without crashing. Developers should also verify that error messages are informative and precise so that users can easily understand and resolve issues that arise.
5. Monitor and maintain the integration
When the API integration is accomplished, developers need to track its performance, such as processing requests within a specified time frame, handling a specific number of requests, or meeting other essential metrics. It’s also important to regularly review the API documentation for any changes or updates that may impact the integration.
If the API undergoes changes or updates, the integration may need to be updated to remain compatible with new requirements. Moreover, keeping the software up-to-date with the latest security patches and updates is crucial to ensure data security and protection from cyber threats.
In many cases, a large team of developers is not needed for further support, and an outstaffing back-end specialist is quite enough. However, complex information systems require the participation of different specialists. Therefore, the maintenance of API integrations for enterprise software is often performed by dedicated teams of outsourced experts.
