Which of the following describes the correct HTTP method to use for updating a resource in Genesys Cloud?

The appropriate HTTP method for updating a resource, particularly in the context of RESTful APIs like those used in Genesys Cloud, is the PUT method. The PUT method is specifically designed to modify an existing resource or create a resource at a specific URL when it does not yet exist. When you make a request using PUT, you are intending to update the entire resource with the request payload you provide.

In practice, this means that when you need to send a complete representation of a resource to replace its current state for an API in Genesys Cloud, you use PUT to execute that update. It is crucial to understand that using PUT replaces the resource completely, so the client must include all fields that are required by the resource in the request body.

While PATCH could also be considered for updates in some contexts, it is typically employed for making partial updates to a resource, meaning that only the specified fields will be altered rather than replacing the entire resource. Therefore, in scenarios where a complete update is required, PUT is indeed the correct choice.

Understanding the distinctions between these methods is vital for effective interaction with APIs, as they dictate how resources are managed and modified within systems like Genesys Cloud.
