𝗘𝘃𝗲𝗿 𝘄𝗼𝗻𝗱𝗲𝗿𝗲𝗱 𝘄𝗵𝘆 𝘀𝗼𝗺𝗲 𝗔𝗣𝗜 𝗿𝗲𝗾𝘂𝗲𝘀𝘁𝘀 𝗰𝗮𝗻 𝗯𝗲 𝗿𝗲𝗽𝗲𝗮𝘁𝗲𝗱 𝗲𝗻𝗱𝗹𝗲𝘀𝘀𝗹𝘆 𝘄𝗶𝘁𝗵𝗼𝘂𝘁 𝗰𝗮𝘂𝘀𝗶𝗻𝗴 𝗰𝗵𝗮𝗼𝘀, 𝘄𝗵𝗶𝗹𝗲 𝗼𝘁𝗵𝗲𝗿𝘀 𝗻𝗲𝗲𝗱 𝘁𝗼 𝗯𝗲 𝗵𝗮𝗻𝗱𝗹𝗲𝗱 𝘄𝗶𝘁𝗵 𝗰𝗮𝗿𝗲? 🤔 This depends on the 𝗶𝗱𝗲𝗺𝗽𝗼𝘁𝗲𝗻𝗰𝘆 nature of the API. Let's understand what do we mean by idempotent? 𝗜𝗱𝗲𝗺𝗽𝗼𝘁𝗲𝗻𝘁 𝗢𝗽𝗲𝗿𝗮𝘁𝗶𝗼𝗻𝘀: 𝗧𝗵𝗲 𝗦𝘂𝗽𝗲𝗿𝗵𝗲𝗿𝗼𝗲𝘀 𝗼𝗳 𝗦𝘁𝗮𝗯𝗶𝗹𝗶𝘁𝘆 Imagine you’re managing a banking app. You have an endpoint to set a customer's account balance 💵 : 𝙿𝚄𝚃 /𝚊𝚌𝚌𝚘𝚞𝚗𝚝𝚜/𝟷𝟸𝟹𝟺𝟻/𝚋𝚊𝚕𝚊𝚗𝚌𝚎 { "𝚋𝚊𝚕𝚊𝚗𝚌𝚎": 𝟻𝟶𝟶𝟶 } You send a request to set the balance to Rs. 5000. But, oops! You hit the "send" button three times by accident. No worries! Thanks (or no thanks!) to the 𝗶𝗱𝗲𝗺𝗽𝗼𝘁𝗲𝗻𝘁 nature of the PUT request, the account balance will still be Rs. 5000. Whether you send it once or a hundred times, the outcome is the same (better luck next time!). This makes retrying failed requests safe and predictable. 𝗡𝗼𝗻-𝗜𝗱𝗲𝗺𝗽𝗼𝘁𝗲𝗻𝘁 𝗢𝗽𝗲𝗿𝗮𝘁𝗶𝗼𝗻𝘀: 𝗛𝗮𝗻𝗱𝗹𝗲 𝘄𝗶𝘁𝗵 𝗖𝗮𝗿𝗲 Now, let’s switch gears. Say your app also allows to transfer money 🏦 : 𝙿𝙾𝚂𝚃 /𝚊𝚌𝚌𝚘𝚞𝚗𝚝𝚜/𝟷𝟸𝟹𝟺𝟻/𝚝𝚛𝚊𝚗𝚜𝚏𝚎𝚛 { "𝚊𝚖𝚘𝚞𝚗𝚝": 𝟷𝟶𝟶, "𝚝𝚘𝙰𝚌𝚌𝚘𝚞𝚗𝚝": "𝟼𝟽𝟾𝟿𝟶" } You send a request to transfer Rs. 100 to account 67890. But then, your internet hiccups, and you click "send" again... and again. Each click results in an additional Rs. 100 being transferred! Because POST is 𝗻𝗼𝗻-𝗶𝗱𝗲𝗺𝗽𝗼𝘁𝗲𝗻𝘁, each request creates a new transaction, potentially draining the account unintentionally. 𝗪𝗵𝘆 𝗜𝘁 𝗠𝗮𝘁𝘁𝗲𝗿𝘀? Reliability: Idempotent operations ensure that retrying requests (due to network issues or user error) doesn’t cause unintended side effects. Safety: Developers can design APIs that are resilient to failures and reduce the risk of duplications. Simplicity: Debugging and maintaining systems becomes easier when repeated actions produce consistent results. Next time you design an API or troubleshoot a network glitch, remember the magic of idempotency! #APIs #SoftwareEngineering #WebDevelopment #TechInsights #Idempotency #BankingTech

Low-code platforms are transforming how financial institutions approach digital solutions. Here are five key insights to keep in mind: 1️⃣ Speed and Agility: Low-code development accelerates project timelines, enabling teams to adapt quickly to changing market demands. 2️⃣ Empowering Teams: It allows non-technical staff to contribute to app development, fostering collaboration and innovation across departments. 3️⃣ Enhanced Customer Experiences: With the ability to create tailored applications, banks can meet specific customer needs more effectively. 4️⃣ Cost Efficiency: Low-code solutions can reduce development costs by minimizing reliance on traditional coding resources. 5️⃣ Integration Made Easy: Seamlessly connect with existing systems to enhance operational efficiency without overhauling infrastructure. 👉 Read more here: https://lnkd.in/eXzHjCUw #LowCode #ThinKinetech #LowCode #Mendix #FinancialServices #Innovation

Nothing feels disappointing and frustrating to both owners and users like a software digital product already launched into the real market place and fails to function as expected. It's the worst experience that often happens to businesses around the world. Such small oversights in business can mean a big deal in revenue because of a potentially high customer churn. Since human is not perfect, and the product always scales, automated testing can help prevent embarrassment and loss. For instance, imagine when user tries logging in with the right credentials then an internal error occurs and throws a user out of your application. Then, an email is auto-sent to the admins and/or developers notifying them of something that happened(an error) with more information. Wouldn't this be great? It's at this point when the product error can be corrected and the product iterated, and the level of severity will be known by developer in real time even before users notice of anything that just happened. That's why agility is a great concept though overly controversial in the software. #API #Reliability #Testing #Integration #ErrorReduction

These days, all IT conferences are focused on AI, low-code/no-code, and microservices. These three concepts aren't naturally very compatible, but they can be reconciled and integrated into a common platform that works well. The following "snippet" provides a personal insight into this integration process. Enjoy :-)

Ever wondered what makes your favorite apps tick? APIs, or Application Programming Interfaces, are the unsung heroes behind the seamless functionality of modern software. They allow different software applications to communicate and share data, making it possible for your weather app to pull real-time updates, your social media platforms to interact, and your online banking services to function securely. Think of APIs as digital bridges that connect various services and enable them to work together harmoniously. They provide the building blocks for developers to create robust, scalable, and feature-rich applications without reinventing the wheel. A behind-the-scenes look reveals that APIs handle everything from user authentication to data retrieval, ensuring your applications are efficient and user-friendly. They play a critical role in integrating third-party services, enabling functionalities like payment gateways, mapping services, and even AI-powered features. APIs are the backbone of the digital world, empowering innovation and simplifying complex processes. Want to learn more about the power of APIs?
