  • Filters (list) –

    Filters applied to the limitations described in the form of key-value pairs.

    • (dict) –

      Identifies the name and value of a filter object. This filter is used to limit the number and type of DMS objects that are returned for a particular Describe* call or similar operation. Filters are used as an optional parameter for certain API operations.

      • Name (string) – [REQUIRED]

        The name of the filter as specified for a Describe* or similar operation.

      • Values (list) – [REQUIRED]

        The filter value, which can specify one or more values used to narrow the returned results.

        • (string) –

  • MaxRecords (integer) – The maximum number of records to include in the response. If more records exist than the specified MaxRecords value, Fleet Advisor includes a pagination token in the response so that you can retrieve the remaining results.

  • NextToken (string) –

    Specifies the unique pagination token that makes it possible to display the next page of results. If this parameter is specified, the response includes only records beyond the marker, up to the value specified by MaxRecords.

    If NextToken is returned by a previous response, there are more results available. The value of NextToken is a unique pagination token for each page. Make the call again using the returned token to retrieve the next page. Keep all other arguments unchanged.
