How would you handle exceptions in REST APIs?

• Implement global exception handling using middleware to catch unhandled

exceptions.

• Return consistent and meaningful error responses.
• Log errors for debugging and monitoring.

Example in ASP.NET Core:

pp.UseExceptionHandler(appError =>

{

ppError.Run(async context =>

{
context.Response.StatusCode = 500; // Internal Server Error
context.Response.ContentType = "application/json";
var contextFeature =

context.Features.Get<IExceptionHandlerFeature>();

if(contextFeature != null)
{

// Log exception (use ILogger)

wait context.Response.WriteAsync(new

{

StatusCode = context.Response.StatusCode,

Message = "Internal Server Error.",

Detail = contextFeature.Error.Message

}.ToString());

}

});

});
