Query parameters — the standard list contract: p, n, sortBy, sortOrder, searchBy, searchValue, filters, advancedFilters, ids, nids. See Pagination and Filtering.

Response — data is an array of Payment objects, alongside the pagination fields described in Response format. updatedBy, createdBy, subscription are populated, so they arrive as nested objects rather than ids.
