True or False: Client requests to an API must include all information for the request to be actioned.

The statement that client requests to an API must include all information for the request to be actioned is true in many contexts where APIs require specific parameters to fulfill a request. APIs are designed to accept certain inputs to process requests effectively. If a required piece of information is missing from the request, the API typically responds with an error message indicating what information is needed. This ensures that the API can perform its intended function and return the correct results to the user.

In some cases, APIs might have optional parameters which can enhance the request but are not strictly necessary for the request to be processed. However, when it comes to essential or mandatory parameters, a complete request is necessary for successful execution. Therefore, for standard API interactions, it is accurate to state that all required information must be included for the request to be actioned.

Other options suggest scenarios that either introduce conditions or consider optional parameters, but these do not apply universally to all API requests. Thus, the straightforward assertion that all required information must be present aligns with the common practice observed in designing and using APIs.
