Query Parameters
-
limit(optional): integer(int32)
The maximum number of records to return.
-
q(optional): string
Filtering is the process of limiting a collection resource by using a per-request dynamic filter definition across multiple page resources, where each page contains a subset of items found in the complete collection. Filtering enables efficient traversal of large collections.
