What does the `nextPageKey` signify in Dynatrace API responses?

The nextPageKey in Dynatrace API responses is used for API pagination handling. When dealing with APIs that return large sets of data, it's common to receive responses in a paginated format to avoid overwhelming the client or the server. The presence of a nextPageKey indicates that there are more results available beyond the current page. This key allows the client to make subsequent requests to retrieve additional data by using the nextPageKey in the next API call.

This mechanism is crucial for efficiently managing large datasets, as it breaks down the information into manageable sections, facilitating smoother data retrieval without overloading the system. It allows users to navigate through the data sequentially while keeping track of their place within the dataset.

Understanding this concept is essential for working with APIs effectively, especially in scenarios where data sets can be extensive and require systematic access.
