# Retrieving Parameter IDs
Parameters are essential components that can be included with an endpoint to modify the behavior and response obtained from the PlexTrac API. These parameters serve as options, allowing users to customize their requests, retrieve specific information, or perform specific actions.
The following is a compilation of commonly used parameters in various PlexTrac API endpoints, accompanied by an explanation of locating the corresponding values within the platform to fulfill each request's specific requirements.
## Tenant IDs
The `tenantId` is returned when an authentication API is requested, as shown here:
## Client IDs
The `clientId` can be retrieved from the platform by going to the **Clients** module, clicking the desired client, and looking at the numerical value in the URL between "clients" and "reports" in the URL path.
## Finding IDs
The `findingId` can be retrieved from the platform by going to a client or report, clicking the **Findings** tab, clicking the desired finding, and looking at the **Finding ID** field.
## Report IDs
