Before this, I didn’t even know such services existed! My goal was to understand how these APIs work, how to test them, and how to integrate them into real applications.</p> <p>I started by exploring the <a href="https://www.easysendsms.com/" rel="noopener noreferrer">EasySendSMS</a> API and reading their API documentation in <a href="https://www.postman.com/easysendsms-6551062/easysendsms-workspace/overview?sideView=agentMode" rel="noopener noreferrer">Postman</a>. Having a clear API reference really helped me figure out how to structure my requests, what parameters were required, and how to handle common errors. For example, I learned about the limits for message length, required phone number formats, and handling HTTP status codes when something goes wrong.</p> <p>The testing process itself was eye-opening. I used Postman to send GET and POST requests, checking how messages were delivered and how errors were returned. One lesson I learned is the importance of properly formatting requests and understanding the response codes—it saved me a lot of confusion when I first started.</p> <p>This experience got me thinking about the potential to develop a global bulk messaging service. By understanding existing APIs and testing them hands-on, I now have a clearer vision of how I might build something scalable, efficient, and developer-friendly in the future.</p> <p>I’d love to hear from other developers: what are your experiences with bulk messaging APIs? Any tips for someone looking to build something similar?</p> api bulksms backend learning
