What is the expected response for an error status code when using REST callbacks?

When working with REST callbacks, the expected response when encountering an error status code is to detect and locally handle the HTTP error status. This approach is crucial because it allows developers to implement appropriate error-handling logic in their applications.

Detecting the error status enables the application to identify what went wrong during the API call and respond accordingly. For example, if the server returns a 404 error indicating that the resource was not found, the application can inform the user or take alternative steps to rectify the situation. This proactive handling enhances user experience and application stability by avoiding unexpected behaviors or crashes.

Additionally, local error handling allows the developer to implement specific responses based on different error codes, which can range from retries on temporary issues to displaying meaningful error messages to users. This level of control is essential in creating robust applications that effectively communicate with various services over the web.

In contrast, displaying a success message in the presence of an error, logging the error and continuing without addressing it, or ignoring the error entirely would lead to poor application behavior and user experience. Therefore, it is imperative to focus on detecting and locally handling errors to maintain the integrity and usability of your application.
