APIs (Application Programming Interfaces) play a critical role in modern software development, allowing different systems to communicate and interact with each other. However, working with APIs comes with its challenges, one of the most crucial being error handling. When an API encounters an issue, it's essential to handle errors gracefully to maintain system reliability and ensure a good user experience. In this article, we'll discuss best practices for API error handling that can help developers manage errors effectively. Why is API Error Handling Important? API error handling is crucial for several reasons: Maintaining System Reliability: Errors are inevitable in any system. Proper error handling ensures that when errors occur, they are handled in a way that prevents them from cascading and causing further issues. Enhancing User Experience: Clear, informative error messages can help users understand what went wrong and how to resolve the issue, improving overall user satisfaction. Security: Proper error handling helps prevent sensitive information from being exposed in error messages, reducing the risk of security breaches. Debugging and Monitoring: Effective error handling makes it easier to identify and debug issues, leading to quicker resolutions and improved system performance. Best Practices for API Error Handling 1. Use Standard HTTP Status Codes HTTP status codes provide a standard way to communicate the outcome of an API request. Use status codes such as 200 (OK), 400 (Bad Request), 404 (Not Found), and 500 (Internal Server Error) to indicate the result of the request. Choosing the right status code helps clients understand the nature of the error without parsing the response body. 2. Provide Descriptive Error Messages Along with HTTP status codes, include descriptive error messages in your API responses. Error messages should be clear, concise, and provide actionable information to help users understand the problem and how to fix it. Avoid technical jargon and use language that is understandable to your target audience. 3. Use Consistent Error Response Formats Maintain a consistent format for your error responses across all endpoints. This makes it easier for clients to parse and handle errors consistently. A typical error response may include fields like status, error, message, code, and details, providing a structured way to convey error information. 4. Avoid Exposing Sensitive Information Ensure that error messages do not expose sensitive information such as database details, API keys, or user credentials. Use generic error messages that do not reveal internal system details to potential attackers. 5. Implement Retry Logic for Transient Errors For errors that are likely to be transient, such as network timeouts or service disruptions, consider implementing retry logic on the client side. However, retries should be implemented judiciously to avoid overwhelming the server with repeated requests. 6. Document Common Errors Provide comprehensive documentation that includes common error codes, messages, and their meanings. This helps developers quickly identify and troubleshoot common issues without needing to contact support. 7. Use Logging and Monitoring Implement logging and monitoring to track API errors and performance metrics. Logging helps you understand the root cause of errors, while monitoring allows you to proactively identify and address issues before they impact users. 8. Handle Rate Limiting and Throttling Implement rate limiting and throttling to protect your API from abuse and ensure fair usage. Return appropriate error codes (e.g., 429 - Too Many Requests) when rate limits are exceeded, and provide guidance on how users can adjust their requests to comply with rate limits. 9. Provide Support for Localization If your API serves a global audience, consider providing support for localization in your error messages. This allows users to receive error messages in their preferred language, improving the user experience for non-English speakers. 10. Test Error Handling Finally, thoroughly test your API's error handling capabilities to ensure they work as expected. Test various scenarios, including valid requests, invalid requests, and edge cases, to identify and address potential issues. Conclusion Effective error handling is essential for building reliable and user-friendly APIs. By following these best practices, you can ensure that your API handles errors gracefully, provides meaningful feedback to users, and maintains high availability and security. Implementing robust error handling practices will not only improve the reliability of your API but also enhance the overall user experience.
AADSTS50011: The reply URL specified in the request doesn't match registered the reply URLs
Is this a common occurrence; does anyone know how to get around this issue? "AADSTS50011: The reply URL specified in the request does not match the reply URLs configured for the application: 'my application client id'. " I've followed the directions explicitly in these two documents, and reviewed others to see if I was missing anything. Reviewing responses to others' issues with the same problem did not resolve the failed auth issue. https://docs.microsoft.com/en-us/azure/app-service/configure-authentication-provider-aad https://docs.microsoft.com/en-us/azure/active-directory/develop/quickstart-configure-app-access-web-apis#add-redirect-uris-to-your-application I have an Azure Web App that has been registered. I can go to Azure Portal Home >> App registrations >> My App >> Endpoints, add all of the OAuth endpoints under the Redirect URIs and still cannot get fully logged in. I tried the <app-url>/.auth/login/aad/callback redirect format from one of the above articles with no success. I've tried https://myapplicationname.azurewebsites.net/.auth/login/aad/callback, https://login.microsoftonline.com/mytenent/oauth2/v2.0/authorize (as well as the three other endpoints with this format), https://login.microsoftonline.com/common/oauth2/v2.0/authorize (same with other three endpoints), etc. When I run in debug on my localhost:44321/ the web app launches, prompts for authentication, and is successful each time, however, always fails with the same subject error any time I deploy the build to Azure. My localhost addresses are listed in the Redirect URIs, so that makes sense the local deployment is successful but I cannot figure out why the deployed web app always fails when it goes live. I've tried everything that I could possibly think of with different combinations, but no luck getting past the auth error so any insights would be greatly appreciated.
How to host moodle on azure
Hello everyone, I am here for help, I am an IT specialist my employer asked me to host a Moodle LMS on azure to be accessible for our program, I have no idea how to do it because I don't have experience on hosting websites and Azure as well. I am willing to learn about azure and how to use to make Moodle available to our benfieries. could you please give me a detailed guideline about that? I am having a free azure subscription right now but I will purchase other packages later once I got a clear idea how to use it. I am looking for your kind answers. Thanks, BarzanWith custom security attributes and conditional access, enforce MFA for web apps!
Dear Microsoft Azure Friends, The use of multifactor authentication (MFA) has become indispensable in today's world. With the help of conditional policies (CA), we can set up MFA in a very targeted manner. But what about when a new web app is set up and deployed? Does it now need a new CA every time? In this article I will show you the custom security attributes with an example where exactly this scenario is addressed. But what exactly are custom security attributes? From Microsoft Documenation: "Custom security attributes in Azure Active Directory (Azure AD) are business-specific attributes (key- value pairs) that you can define and assign to Azure AD objects. These attributes can be used to store information, categorize objects, or enforce fine-grained access control over specific Azure resources." What are custom security attributes in Azure AD? (Preview) https://learn.microsoft.com/en-us/azure/active-directory/fundamentals/custom-security-attributes-overview However, before you can work with or create custom security attributes, you need the necessary permissions. You can find all the necessary information in the above mentioned article. At this point it is worth mentioning that not even a "Global Admin" by default has the right to create the attributes. The ingenious thing is that the roles are divided. One person can create the attributes, another person does the assignment. Now we navigate to Azure Active Directory to the custom security attributes. Here you can create an attribute set and specify the key values. Then, in Enterprise Applications, find your app and assign the custom security attributes. Now we can create the conditional access policy. After you have selected the name, you can now select for whom the policy should apply. I have used a group named "Bitcoin" for this example. This group includes the Tina Muff. Now comes the exciting part. In "Cloud apps or actions", we do not select a specific app in "include" but use the filter function. This function is on the preview and first you need to set the switch to configured. After that you can select your custom security attributes. At this point, use exactly the same key value pair that you selected for your enterprise app. Next, you can define how the access should take place at "Access controls". I have selected that access is allowed but only with multifactor authentication. Now when Tina Muff calls the WebApp, she will be prompted to apply MFA (this account is a test account, so the MFA setup has not been done). Sorry it's in german ;-). So what's the point of all this effort? If you now continue to set up and provide WebApps in the future. You simply have to assign your custom security attributes to the WebApp again with the corresponding key value pair, and you already have to work with MFA when you call the app because the CA is already present. I realize that this was not necessarily spectacular. It was simply important for me to share my experience with you. Nevertheless, I hope that this article was helpful. Thank you for taking the time to read the article. Best regards, Tom Wechsler P.S.

Hi Cloud Friends, Today, developers build apps by integrating user and enterprise data from cloud platforms to enhance and personalize experiences. These cloud platforms are rich in data, but in turn have attracted malicious actors who attempt to gain unauthorized access to that data. One such attack is consent phishing, in which attackers trick users into granting a malicious app access to sensitive data or other resources. Instead of trying to steal the user's password, an attacker asks for permission for an app controlled by the attacker to access valuable data. These apps are often named to mimic legit apps, such as “0365 Access” or “Newsletter App”. Here is one way to counteract these attacks. 1. Restricting users from registering new apps to Azure AD: 2. Preventing the users for giving consents to apps: When you make these settings you need to know that as an administrator you will have to make the apps available to the users. So this means that you as an administrator will have more work. As an administrator for the respective app (enterprise application), you should configure the consent for the necessary permissions on behalf of the user. But really do not flip the "big switch" that all users can give consent of permissions for ALL apps. Enormously important is also the training for the users. In many cases, such apps are not described correctly, or the spelling is wrong. Training your users regularly is another way to counter these attacks. I hope this article was useful. Best regards, Tom Wechsler
Using Claude Opus 4.6 in Github Copilot
The model selection in Github Copilot got richer with the addition of Claude Opus 4.6. The Model capability along with the addition of agents makes it a powerful combination to build complex code which requires many hours or days. Claude Opus 4.6 is better in coding skills as compared to the previous models. It also plans more carefully, performs more reliably in larger codebases, and has better code review as well as debugging skills to catch its own mistakes. In my current experiment, I used it multiple times to review its own code and while it took time (understandably) to get familiar with the code base. After that initial effort on the evaluation, the suggestions for fixes/improvements were on dot and often even better than a human reviewer (me in this case). Opus 4.6 also can run agentic tasks for longer. Following the release of the model, Anthropic published a paper on using Opus 4.6 to build C Compiler with a team of parallel Claudes. The compiler was built by 16 agents from scratch to get a Rust-based C compiler which was capable of compiling the Linux kernel. This is an interesting paper (shared in resources). Using Claude Opus 4.6 in Agentic Mode In less than an hour, I built a document analyzer to analyse the content, extract insights, build knowledge graphs and summarize elements. The code was built using Claude Opus 4.6 alongwith Claude Agents in Visual Studio Code. The initial prompt built the code and in the next hour after a few more interactions - unit tests were added and the UI worked as expected specifically for rendering the graphs. In the second phase, I converted the capabilities into Agents with tools and skills making the codebase Agentic. All this was done in Visual Studio using Github Copilot. Adding the complexity of Agentic execution was staggered across phases but the coding agent may well have built it right in the first instance with detailed specifications and instructions. The Agent could also fix UI requirements and problems in graph rendering from the snapshot shared in the chat window. That along with the logging was sufficient to quickly get to an application which worked as expected. The final graph rendering used mermaid diagrams in javascript while the backend was in python. Knowledge Graph rendering using mermaid What are Agents? Agents perform complete coding tasks end-to-end. They understand your project, make changes across multiple files, run commands, and adapt based on the results. An agent runs in the local, background, cloud, or third-party mode. An agent takes a high-level task and it breaks the task down into steps. It executes those steps with tools and self-corrects on errors. Multiple agent sessions can run in parallel, each focused on a different task. On creating a new agent session, the previous session remains active and can be accessed between tasks via the agent sessions list. The Chat window in Visual Studio Code allows for changing the model and also the Agent Mode. The Agent mode can be local for Local Agents or run in the background or on Cloud. Additionally, Third Party Agents are also available for coding. In the snapshot below, the Claude Agent (Third Party Agent) is used. In this project Azure GPT 4.1 was used in the code to perform the document analysis but this can be changed to any model of choice. I also used the ‘Ask before edits” mode to track the command runs. Alternatively, the other option was to let the Agent run autonomously. Visual Studio Code - Models and Agent Mode The local Agentic mode was also a good option and I used it a few times specifically as it is not constrained by network connectivity. But when the local compute does not suffice, the cloud mode is the next best option. Background agents are CLI-based agents, such as Copilot CLI running in the background on your local machine. They operate autonomously in the editor and Background agents use Git worktrees to work in an isolated environment from your main workspace to prevent conflicts with your active work. How to get the model? The model is accessible to GitHub Copilot Pro/Pro+, business, and enterprise users. Opus 4.6 operates more reliably in large codebases, offering improved code review and debugging skills. The Fast mode for Claude Opus 4.6, rolled out in research preview, provides a high-speed option with output token delivery speeds up to 2.5 times faster while maintaining comparable capabilities to Opus 4.6.
