What happens if a PUT request is made multiple times?

• A. A new resource is created each time
• B. The state of the resource remains the same
• C. An error occurs
• D. Only the first request is processed

Answer: (B)

When a PUT request is made multiple times to an API endpoint, it is designed to update an existing resource with the same data each time. Since PUT is idempotent, meaning that making multiple identical requests results in the same state as making a single request, the state of the resource does indeed remain consistent. Thus, if the first PUT request successfully updates the resource, subsequent requests with the same data will not change the resource's state; they will reaffirm it. This characteristic of PUT helps ensure that the resource can be set to a desired state consistently without risking the creation of duplicate resources or unintended modifications. This reasoning underlines why the correct answer reflects the behavior of the PUT request in RESTful interactions. When understanding RESTful APIs, recognizing the idempotent nature of the PUT method is crucial for predicting how multiple requests will affect the system's resources.
