`GET https://api.desktopaccountingapi.com/v1/quickbooks-desktop/estimates`

Operation ID: `qbd.estimates.list`. Tag: Estimates.

Returns the estimates that match your filters. Results are paged: pass `nextCursor` as `cursor` until `hasMore` is false. A cursor lives only inside the current QuickBooks session, so request the next page promptly; an expired cursor returns `410 CURSOR_EXPIRED`. See [Pagination](https://www.desktopaccountingapi.com/docs/guides/pagination/).
