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

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

🚀 Harnessing the Power of #Asynchronous Operations and #API Integration! 🚀 Today, I want to share a snippet from my banking app #fintech, where I worked on integrating with the #PlaidAPI to fetch account information for users. This code demonstrates the power of asynchronous operations and the importance of clean, structured #datamanagement. 🔍 The Challenge: I needed to retrieve account details from multiple banks associated with a user and then enrich that data with additional institution information. This involved: -Fetching bank details from the database. -Querying the Plaid API for account information. -Cross-referencing the institution details. -Returning a clean and comprehensive account object for each bank. 💡 The Solution: Using JavaScript's Promise.all and async/await syntax, I efficiently handled multiple API requests concurrently while ensuring data consistency and error handling. 🌟 Key Takeaways: Efficiency: Leveraged Promise.all to handle multiple asynchronous operations concurrently, reducing wait times. Error Handling: Wrapped the logic in a try-catch block to gracefully handle any potential errors. Data Integrity: Ensured that all mutable data was properly managed, making the system robust and reliable. This approach not only improved the performance but also made the code more maintainable and scalable. 👩💻 Whether you're working with #APIs, managing data, or ensuring seamless user experiences, these principles are crucial in modern web development. #javascript #webdevelopment #APIintegration #asynchronousprogramming #tech

API testing is the foundation of reliable software. Think of APIs as the connections between different systems, allowing them to communicate and work together. Testing APIs is essential to ensure they’re performing smoothly and securely, handling everything from data transfer to user interactions. When an API fails, it impacts the entire user experience, whether it’s on a website, app, or service. Effective API testing helps catch issues early, ensuring that every request, response, and process works as expected across devices. In our API Testing course, we cover every critical aspect, from setting up basic tests to handling complex scenarios and automation. Curious about how this fits into modern software development? Stay with us this week as we explore the details of API testing and why it’s crucial in today’s connected world. #apitesting #softwarequality #cdpl #techskills #automation #softwaretesting

In today’s digital age, the race for business success is relentless, and companies must constantly evolve to stay competitive. At the heart of this evolution lies the powerful tool known as APIs (Application Programming Interfaces). Yet, surprisingly, some companies are still hesitant to fully embrace APIs, unaware of the significant competitive disadvantage they face by doing so.

How API handles 200 billion requests daily? Ever wondered how your favorite apps communicate seamlessly with each other? What is an API? 🤔 An API is like a waiter in a restaurant. You (the client) tell the waiter (API) what you want, and the waiter tells the kitchen (server) to prepare it. Once ready, the waiter brings it back to you. Similarly, an API acts as a middleman between different software applications, enabling them to interact and share data efficiently. How APIs Work 🛠️ Request: The client sends a request to the server via the API. This request is usually in the form of an HTTP request and includes the desired endpoint and parameters. Processing: The server processes the request, often interacting with a database or other services to gather the necessary information. Response: The server sends back a response, typically in JSON or XML format, containing the requested data or the result of the requested action. Why APIs Matter 💡 Interoperability: APIs allow different systems and applications to work together, regardless of their underlying technologies. This is crucial for integrating diverse systems in a cohesive way. Efficiency: They streamline processes by automating the exchange of data, reducing the need for manual intervention and minimizing errors. Scalability: APIs enable businesses to scale their services by allowing third-party developers to build on top of their platforms. This can lead to new functionalities and innovations without the need for significant internal development. Security: With proper authentication and authorization mechanisms, APIs ensure that only authorized users can access sensitive data and functionalities. Real-World Examples 🌐 Social Media Integration: Ever noticed how you can log into various websites using your Facebook or Google account? That's an API at work, allowing these platforms to verify your identity seamlessly. Payment Processing: Online payment gateways like PayPal and Stripe use APIs to handle transactions securely and efficiently. Curious about APIs? Have any experiences or questions?
