API: What an Application Programming Interface Is and How It Helps Your Business

An API is the bridge that lets two systems talk without human help. When a customer pays online and receives a confirmation, APIs carried that information between systems.
Key points
- APIs save time by removing manual copying between tools.
- Common examples: payment gateways, shipping, maps, WhatsApp messaging, accounting.
- Keep API keys secret and use HTTPS.
- Check pricing and limits before relying on an API.
- Document which APIs your project uses and who owns the keys.
