APIs (Application Programming Interfaces) are everywhere in today’s digital landscape. We tend to interact with them without even realizing it. For instance, every time we check – the weather or book a flight ticket, we use them behind the scenes. But have you ever wondered how these APIs talk to each other? That’s where API integration comes in.
A common conundrum associated with API integration is the challenge to integrate unique APIs with different data formats and structures. It becomes trickier when businesses evolve in size and need to connect with newer ones.
How then can compatibility and consistency be ensured across integrations, particularly with frequent updates to APIs?
Read on to learn more about API integration, its benefits for businesses, common use cases, selecting the appropriate integration solution, and what an implementation would entail.
An Introduction to API Integration
API integration is vital to businesses today. Chances are, if you have used a 3rd-party application or service, you have already experienced API integration in action.
But before we go any further, let’s take a step back and understand what APIs are in the first place.
Demystifying APIs
During my decade-long career as a software developer, I have frequently encountered the need to explain the concept of APIs to individuals without a technical background. I have come to appreciate the following analogy:
When operating a vehicle, the primary concern is driving. You might not always be well-versed in the intricacies of the engine or the components at play. As a result, any unnecessary information is concealed while you only focus on the task at hand.
The illustration highlights the programming concept of abstraction, where details are concealed to present only the most pertinent information to the driver.
APIs provide an abstraction layer for software applications, providing subroutines, protocols, and tools necessary for their development.
They also set rules for how applications and database servers interact with each other through a request/ response mechanism.
But just like with friends, you have to speak the same language! So you must send a request in a format that the API can understand. If not, it will kindly let you know with an error message.
They are platform-independent. So you can fetch any information from an application without worrying about your technology stack.
APIs offer endpoints. These are URLs you can use to refer to the exposed data.
To maintain security, sometimes APIs may require authentication.
Note: REST (Representational State Transfer) APIs are the most popular architectural style for web-based applications. There are also others like SOAP (Simple Object Access Protocol) and RPC (Remote Procedure Call), not so common.
Many software vendors or providers offer public (or open) APIs that developers can use to access software applications or web services.
But how to connect these APIs that have different formats and structures? How can you innovate faster with APIs? How to ensure communication between proprietary applications reaches new levels of service delivery and achieves flexibility in information exchange?
API integration plays a crucial role in this context.
What is API Integration
Businesses use a lot of applications – SaaS, custom-built, legacy, ERPs, CRMs, etc. Teams using these applications will benefit from working together.
The development team can benefit from input from the support teams. Or they might want to collaborate with the marketing team to create better marketing campaigns.
API integration is the process of connecting multiple APIs. It enables the transfer and synchronization of information for a successful business operation or informed decision-making.
Additionally, it can transform data between two application APIs while maintaining data integrity.
Think about an e-commerce website that automatically integrates with a shipping carrier’s API, calculates shipping rates, and generates shipping labels. The integration can streamline the order fulfillment process and ensure accurate and timely delivery information.
If teams leverage the power of APIs, they can create integrations that are more scalable, flexible, and adaptable to business needs.
Still curious about API integration? Let’s explore this further.
Common API Integration Use Cases
Here are some typical examples of API integration in action.
Payment Gateway Integration
Payment gateway integrations can enable secure verification of credit or debit card details. It can also perform other necessary authentications within your application. Rather than building all this from scratch, you utilize readily available APIs.
Automating the Software Development Workflow
Software development can be a complex process. The developers might need to send issues from Jira (a tool they use) to the QA team for testing, who might use a different tool, like Azure DevOps. Statuses need to be updated automatically when any team makes a transition.
Additionally, they may want to simplify access to the application for the front-end developers without in-depth knowledge of the code.
An API integration can automate the software development process by accessing the APIs, automating tasks, or creating new ones to assist team members.
Connecting with a CRM to Enhance Customer Experience
Salesforce (a CRM) is used to manage customer data and interactions.
Imagine fetching customer details and creating records automatically in your ERP system (e.g. Netsuite) in real time. Further automating this based on preset conditions, for instance, an Opportunity State turns “Won”.
You can create consistent, reliable workflows and improve productivity by integrating your CRM with other apps.
The Benefits of API Integration
API integration allows you to put down manual, repetitive tasks and help avoid mistakes that accompany them.
To put this into perspective, it can
- improve team efficiency since they no longer have to dedicate their productive work hours to copy-pasting or toggling between applications.
- optimize collaboration and communication across teams by connecting diverse APIs to perform a joint function.
- enhance reporting and analysis by extracting relevant data from the desired application. For example, you can use ZenRows’ scraping APIs for that purpose.
- elevate service quality and delivery levels by understanding the needs and expectations of customers. It can help identify areas of improvement, such as response times, communication channels, or product offerings.
- maximize the flexibility of information sharing by integrating APIs into applications and deciding what data to receive or how to manipulate it.
Ready to take your data to the next level? Let’s implement an API integration.
How to Implement an API Integration
Implementing an integration is easier than you think. Is it? Think again.
API Integration Process
In API integration, data is pushed and pulled between applications automatically instead of manually.
So it adds three layers to the APIs you want to integrate:
- Abstraction
- Automation
- Transformation
This is done such that data is
- exchanged based on the conditions you specify (uni or bi-directionally).
- updated or created anew when something changes in one of the applications.
- transformed from one format to another.
There are various ways to integrate APIs, some native, some smart, and others outright complex.
It eventually boils down to your business requirements.
Let’s look at some common ways businesses achieve API integration.
Custom-code to Build an API Integration
So you want to create a custom-made integration for your business. Possible? Yes. Feasible? Not so much.
Firstly, you must create the entire integration layer and then provide automation for exchanging information. It means manual hand-written code for transforming, consolidating, refining, and transferring data from diverse sources or applications. This can take weeks or sometimes months to complete. It also wastes a lot of productive development time and resources.
Secondly, consider that each application has its own set of REST APIs. Developers must ensure that they appropriately map, store, capture, and use different data formats.
Thirdly, you need to maintain the integration yourself – manage the APIs, handle downtimes and errors, enable reporting and monitoring, and spend time nurturing it to ensure it works as expected.
Technology develops at the speed of lightning. So does the advancement in the integration construct.
Instead of writing the code yourself, would you prefer someone already did that for you? You can just choose what to send or receive.
In the upcoming section, we discuss 2 other options to get the ball rolling.
Fundamentally, these methods are the same, albeit with a few subtle differences.
Using Native API Integration Capabilities
Lately, software vendors have acknowledged the need for integration.
So, a lot of commercially renowned platforms provide predefined native integrations. These work as middleware that handles the needs of small and large businesses alike.
For instance, with a simple drag-and-drop interface, you can easily integrate popular applications like Jira, Salesforce, Zendesk, ServiceNow, etc.
These native tools connect applications in a point-to-point manner, effectively handling all the complex details for you.
They invoke the necessary APIs. The data is accessed, aggregated, updated, transformed, or exchanged. Therefore, an automation and abstraction layer is in place to facilitate these API calls.
You get an interface to develop your integration flow and decide what data you want to exchange and how you want to exchange it.
But there is also a flip side to this. Native API integrations are often limited in the functionality they offer.
For instance, they are perfect if you only need to send data in a single direction, from one system to another, but not for complex bi-directional workflow orchestrations. Moreover, it is difficult to incorporate any changes in your integration requirements. Sometimes, even a small change can mean you must edit the entire flow.
Third-party integration tools are the preferred and widely accepted approach to integrating APIs, as they eliminate the need to write code from scratch or constrain your integration options.
Integrating with 3rd-Party API Integration Solutions
Before we examine this further, let’s see why a 3rd-party API integration platform can help you reach maximum integration potential.
These tools have the following significant features:
- They provide pre-built integration templates for various applications but also allow custom integrations.
- They handle multiple data types (JSON, XML, etc) and simplify data mapping, eliminating concerns about data formats and architectures.
- They offer various functions for transforming, consolidating, syncing, mapping, and updating data from APIs.
- They support advanced conditional logic and complex mappings for flexible data exchange.
- They offer a comprehensive API integration and management solution that ensures scalability, data integrity, and automation across your entire technology stack.
- They handle security or other GDPR considerations for data exchange.
Using these tools, you can easily implement the following information flow requirements from ServiceNow to Jira:
And have an entirely new set of requirements for information flow from Jira to ServiceNow.
As evident, most integration solutions perform the same basic function, and numerous options are available in the market. However, by asking the right questions and selecting a solution that aligns with your specific integration needs, you can reach a decision.
API Integration Tools: Key Questions to Ask
Almost there!
Honestly, there isn’t a right or wrong choice.
It all depends on a few questions you may ask.
- What does the solution primarily do? Is it automation, synchronization, transformation, or real-time data streaming?
- How does the tool ensure security measures are in place?
- What is the pricing model for the API integration service it offers? Is it connector-based with an adaptive price model or a flat rate for unlimited integrations?
