An API — Application Programming Interface — is simply a way for two pieces of software to talk to each other. That’s it. No jargon required.
A Real Example
When you check the weather on your phone, the app sends a request to a weather service’s API asking “what’s the weather in Manchester?” The API sends back the answer. Your app didn’t collect the weather data — it asked another system for it.
Why APIs Matter for Your Business
APIs let different systems share data automatically. Instead of manually exporting a CSV from one system and importing it into another, an API does it in real time.
- Your website takes an order → API sends it to your accounting software.
- A customer fills in a form → API adds them to your CRM.
- An employee submits expenses → API creates a record in your finance system.
When I build a web application for your business, I can integrate it with your existing tools using APIs. Your new system doesn’t exist in isolation — it connects to what you already use.
