Applied 2048 character Limit based on PSA Docs

- GET query strings have a limit of 2048 characters. URL elements count against the total character limit.
- POST is appropriate for more complex queries and does not have the same query string length limits of a GET.
- See [PSA Documentation - REST Basic Queries](https://www.autotask.net/help/DeveloperHelp/Content/APIs/REST/API_Calls/REST_Basic_Query_Calls.htm#Before)
