Retrieving access policies
Access policies configured in your FMC instance can easily be retrieved using the FMC REST API. However, doing GET
requests to list large amounts of data can be computationally expensive for the API server. Imagine you have an API that returns you a list of all the policies in your network. This list might have, as an example, 5,000 entries, and retrieving all the information is computationally expensive. Let's imagine the API would always return a full list of entries. If your script now searches for one specific policy, based on the name, and that entry was the first entry in your list, you would have requested the information about the other 4,999 access policies without using the information. To lessen the load on API servers, most REST APIs employ a concept called pagination when dealing with large lists of items.
Instead of always returning all entries, they return you a selection—let's say 50 entries. This response is called a page...
