🚀 REST API Tip: Does 404 mean 204? 🤔 Many developers get confused between HTTP 404 and HTTP 204 when designing APIs, and this can lead to unexpected behavior for API consumers. 📌 Let’s clarify the difference: 🔹 204 No Content Indicates that the operation was successful, but the server has no content to return. Example: DELETE /users/123 If the user with ID 123 existed and was deleted successfully, the server might return 204 No Content. ✅ Operation succeeded – but no data to return. 🔹 404 Not Found Indicates that the requested resource does not exist. Example: DELETE /users/999 If there’s no user with ID 999, the server returns 404 Not Found. ❌ The resource you tried to delete does not exist. ⚠️ Common mistake: Returning 404 instead of 204 when the delete operation succeeds but there’s nothing to return. Remember: 404 means the resource was never there, not “there’s no content to show.” 🧠 Key takeaway: ✅ 204 → Operation successful, but no content. ❌ 404 → Resource not found. 🎯 Use the right status code to make your API clear and predictable. #software #software_developers #restful #api #rest_api #status_code

⚙️ Understanding API Status Codes — The Language of the Web Every time your frontend talks to the backend, the API replies with a status code — a tiny number that says a lot. Here’s what those codes really mean (and when to use them) 👇 ✅ 200 OK — Everything worked exactly as expected. The gold standard. 🆕 201 Created — A new resource was successfully created (think POST requests). 🫥 204 No Content — Request succeeded, but there’s no data to send back — perfect for DELETEs. 🔁 301 Moved Permanently — The resource has a new home. Update your routes. 🧭 302 Found — Temporary redirect — used when the resource moves for now. 🚫 400 Bad Request — The client messed up. Invalid parameters, bad payload, etc. 🔐 401 Unauthorized — Missing or invalid authentication credentials. 🚷 403 Forbidden — You’re authenticated, but still not allowed to access this resource. ❌ 404 Not Found — The resource doesn’t exist (or was deleted). ⚔️ 409 Conflict — A conflict in request state — often during concurrent updates. 🔥 500 Internal Server Error — The server broke something. Time to check the logs. ⚙️ 502 Bad Gateway — The server got an invalid response from an upstream service. ⏱️ 504 Gateway Timeout — The server waited too long for a response. Knowing your status codes isn’t just about debugging — it’s about building APIs that communicate clearly, handle failures gracefully, and make your integrations predictable. Which one have you misused (or seen misused) the most? 👇 #BackendDevelopment #WebDevelopment #APIs #SoftwareEngineering #RESTAPI

API was slow. Everyone blamed .NET.” Turns out, .NET wasn’t the villain. The database was. A single missing index was turning a 300ms query into a 4-second bottleneck. One line fixed it all: CREATE INDEX IX_UserId ON Orders(UserId); Lesson learned? Before you optimize code — optimize what your code talks to. Backend issues often live one layer below where we’re looking.

If there's one thing I've learned about performance issues over 25 years, it is that the performance bottleneck is always somewhere else than I assume. 🤭👌 Very often go for bugs too.

Why Every API Should Have Proper Error Handling?? Building APIs is easy. Handling errors properly that’s what makes an API reliable. When something goes wrong, don’t just throw a 500 error or a random message. A good API should tell what went wrong and why in a clear way. For example: { "status": 400, "error": "Invalid Input", "message": "Email format is incorrect" } This helps both developers and users understand the issue quickly. Simple tips: ✅ Use correct HTTP status codes (400, 404, 500, etc.) ✅ Always return a clear message ✅ Never expose sensitive data in error responses ✅ Log all errors internally for debugging Good error handling doesn’t just fix bugs it builds trust. #SpringBoot #API #ErrorHandling #BackendDevelopment #CleanCode

🚀 Understanding the Most Common HTTP Status Codes for Developers As developers, we deal with APIs and web requests almost every day — and knowing HTTP status codes is crucial for smooth client-server communication. Here’s a quick refresher that I always keep handy 👇 🟢 2xx – Success ✅ 200 OK → The request was successful. 🆕 201 Created → A new resource has been created successfully. 🟠 3xx – Redirection 🔁 301 Moved Permanently → The resource has been moved to a new URL (permanent redirect). ⏩ 302 Found → The resource is temporarily available at a different URL. 🔴 4xx – Client Errors ⚠️ 400 Bad Request → The server can’t process the request due to invalid input. 🔒 401 Unauthorized → Authentication required or token invalid. 💳 402 Payment Required → Reserved for payment-related APIs. 🚫 403 Forbidden → You’re authenticated, but not allowed to access this resource. ❌ 404 Not Found → The requested resource doesn’t exist. ⚫ 5xx – Server Errors 💥 500 Internal Server Error → Something broke on the server side. 🚧 502 Bad Gateway → Invalid response from an upstream server. 🖥️ 505 HTTP Version Not Supported → The server doesn’t support the HTTP version used in the request. 💡 Pro Tip: When you’re building or debugging APIs, using the right status code saves you (and your teammates) hours of confusion — they speak louder than console logs! 😄 👨💻 Keep learning, keep coding, and keep improving every day. #WebDevelopment #APIs #BackendDevelopment #JavaDeveloper #SpringBoot #FullStackDeveloper #CodingTips #HTTPStatusCodes #WebDev #RESTAPI #DevelopersCommunity #TechLearning #Trending #Viral #latest

🧩 REST vs SOAP vs gRPC vs GraphQL vs WebHooks vs WebSockets vs WebRTC — The Ultimate API Showdown.PART(1) APIs are the lifeblood of modern software. But here’s the thing: Not all APIs are created equal. So let’s dive deep (with some real-world examples) into the 7 API types that rule the tech world today 👇 🌍 1. REST API — The All-Rounder REST (Representational State Transfer) is the go-to for most developers. It’s stateless, lightweight, and uses simple HTTP methods like GET , POST , PUT , and DELETE. 🔹 Format: JSON 💡 Example: GET https://lnkd.in/grE58XZJ ✅ Pros: Easy to build and test ⚠️ Cons: No strict contracts 🏁 Best for: Most modern web/mobile development 🧱 2. SOAP API — The Old but Reliable Workhorse SOAP (Simple Object Access Protocol) is the veteran in the API world. It’s strict, structured, and super reliable. 🔹 Format: XML <soap:Envelope> <soap:Body> <GetUserInfo>...</GetUserInfo> </soap:Body> </soap:Envelope> ✅ Pros: Built-in error handling ⚠️ Cons: Verbose and heavy (XML 😩) 🏁 Best for: Mission-critical systems needing guaranteed delivery https://lnkd.in/g5JvU6gM
