In today’s digital-first world, it’s not enough for software to just “work” – it needs to work together. In this blog, we’ll break down what APIs are, how they work, and why they may be important for your business.
What is an API?
API stands for Application Programming Interface and they allow different pieces of software to connect and work together. Whether you’re syncing your website with your CRM, pulling in live stock data, or enabling payments through your e-commerce platform, there’s likely an API running behind the scenes to make it all happen.
Think of it as a digital translator. If your website wants to pull data from another system, it uses an API to make that request and receive a response. This lets you automate tasks, streamline processes, and deliver better experiences to your users without having to build everything from scratch.
Where you’re already using APIs (even if you don’t know it)
Here are just a few ways APIs show up in your daily life – even if you don’t realise it:
- Google Maps in Apps: When you see a map inside Uber or a delivery app, that’s often powered by the Google Maps API.
- Payment Processing: Online checkouts using a payment gateway like Stripe or PayPal use APIs to process your payment securely.
- Social Media Sharing: Clicking “Share on LinkedIn”? That’s done through LinkedIn’s API.
- Weather Widgets: Websites often pull live weather data from services like OpenWeather using an API.
How do APIs work?
At a basic level, APIs follow a simple request-and-response model.
One system (the client) sends a request to another system (the server) via the API. The API acts as the middleman – it checks that the request is valid, processes it, and sends back the right data or action in return.
Each of these requests is directed to a specific endpoint – a defined address within the API that represents a particular function or resource. Think of an endpoint as the part of the API that says, “this is where you go to get order details” or “this is where you send new payment information.”
For example, if a customer uses your website to check delivery status:
-
Your site sends a request to your delivery provider’s tracking endpoint.
-
The API fetches the latest tracking data from that location.
-
That information is sent back and displayed to the customer in real time.
In the background, it’s highly technical. But for your business, the result is simple: faster, more efficient systems that work better together.
How is a webhook different from an API?
You may have heard the term ‘webhook’ mentioned alongside APIs, and whilst they serve a similar purpose – helping systems talk to each other – they work in different ways.
An API works on a request-response model. Your system actively asks another system for data.
A webhook, on the other hand, is event-driven. Instead of repeatedly asking for updates, your system simply waits to be notified.
In short:
- APIs pull data (you go and get it).
- Webhooks push data (it’s sent to you as soon as it happens).
In many applications, APIs and webhooks are used side by side:
- A webhook alerts your system that something has changed e.g a new customer has registered.
- Your system then calls the API to get the full details or take the next action.
They’re both essential tools in modern software, and when used together, they help systems stay fast, efficient, and well-integrated.
Why APIs matter for your business
Whether you’re looking to improve efficiency, enhance customer service, or build entirely new digital products, APIs give you the building blocks to do it.
1. They save time and reduce duplication
Manual data entry between platforms increases the risk of error and eats into your team’s productivity. APIs allow systems to update automatically, so you don’t have to enter the same information twice – or chase down missing data.
2. They improve accuracy
When systems share data instantly, you reduce inconsistencies and keep records up to date across the board. That’s especially important for finance, customer service, and reporting functions where outdated information can cause real issues.
3. They create better user experiences
APIs allow you to offer seamless, connected services. Whether that’s showing live order updates, integrating maps, delivery tracking, or pulling through personalised content, your users get faster, more relevant experiences.
4. They enable scalable systems
As your business grows, you’ll likely want to add new tools, features, or services. APIs make it easier to plug in new platforms or replace existing ones without starting development from scratch. That flexibility means your software stack can grow with you.
Get more from your software with the right integrations
APIs might not be visible to your customers, but they play a critical role in how your systems operate behind the scenes. When used well, they streamline processes, eliminate manual tasks, and create a more connected, efficient business.
If your tools aren’t speaking to each other—or your team is spending time on workarounds—it may be time to explore how APIs (and webhooks) can simplify the way you work.
Whether you’re integrating off-the-shelf platforms or building something bespoke, the right API strategy can save time, reduce errors, and unlock new opportunities.
