By default, the Invoices endpoint returns a maximum 50 records per query. To retrieve a specific set of records, specify a date range in the query or, to retrieve more records, pagination is required.

Pagination Method

By default, the Invoices endpoint returns a maximum 50 records per query. Because the response does not provide a total count of the records, we recommend filtering the query by date. Otherwise, the number of pages requested must be arbitrarily set in Klip formulas, however you must ensure this is the minimum number of pages expected so that no empty responses are returned. When empty responses are returned, null dynamic data source instances are created and this can cause unexpected results.

Refer to Data Sources with Multiple Pages for details on how to handle pagination.
