The try block contains the code that you are trying to execute. The catch block catches any exceptions that are thrown by the code in the try block. - **Use the [HandleError] attribute.** This attribute can be applied to controller actions or methods. It tells ASP.NET MVC to handle any exceptions that are thrown by the action or method. - **Inherit from the HandleErrorAttribute class.** This class provides a more flexible way to handle errors. You can override the OnException method to customize how errors are handled. - **Set a global exception handling filter.** This filter can be used to handle all exceptions that are thrown in an application. - **Handle the Application_Error event.** This event is raised when an unhandled exception occurs in an application. You can use this event to handle the exception and prevent it from crashing the application. - **Log errors.** It is important to log all errors so that you can track them and fix them. You can use the System.Diagnostics.Trace class to log errors. - **Provide feedback to the user.** If an error occurs, you should provide feedback to the user so that they know what happened. You can do this by displaying an error message or by redirecting the user to a different page. By following these best practices, you can ensure that your application handles errors gracefully and prevents them from crashing. Here are some additional things to keep in mind when handling errors when consuming APIs in ASP.NET MVC: - You should always try to handle errors as close to the source as possible. This will help to prevent the error from propagating to other parts of your application. - You should use meaningful error messages. The error message should be clear and concise, and it should help the user to understand what went wrong. - You should not ignore errors. Ignoring errors can lead to unexpected behavior and can make it difficult to track down and fix problems. - You should log errors. Logging errors can help you to track down and fix problems. --- Original Source: https://www.mindstick.com/forum/159774/what-are-the-best-practices-for-error-handling-when-consuming-apis-in-asp-dot-net-mvc Copyright © MindStick Software Pvt.
