Another important lesson I learned is that APIs aren’t just for fetching data. They can also send data, update information, or even trigger actions in other systems. Once I understood this, I started thinking creatively about what I could build. For example, I could send a form submission from my website to a database or even to an external service like Slack or Google Sheets.
If I could give advice to someone starting out, I’d say: don’t get stuck on the technical terms at first. Focus on the concept: an API is a way for applications to talk to each other. Once you grasp that, learning the details endpoints, requests, responses, JSON, authentication becomes much easier.
For me, understanding APIs was a turning point. Suddenly, I could connect my apps to real-world data, integrate external services, and build more useful projects. It made backend development feel less like magic and more like a set of logical tools I could actually use. Once I got this, everything else from REST to GraphQL started making sense.
