⚠️ Experimental endpoint — not yet a stable contract. This resource ships as experimental / beta. While experimental, its schema and behaviour may change without a version bump — including breaking changes within v1.0 itself. Anyone consuming it does so for evaluation only, or by coordinating adoption with their account manager so changes can be sequenced with them. It graduates to a stable, version-locked contract (where the normal breaking-change rules apply) only when this experimental notice is removed.

Get all reimbursement reports. A report is a periodic aggregate that groups the reimbursement records sharing a beneficiary, payer and period, and exposes their totals. For the per-session entries behind those totals, use the reimbursement records listing.

Custom-field criteria use filter[customFields.<identifier>] keys and compose with the ordinary report filters before cursor pagination. Use scalar values for exact or text criteria and from, to, or both below the dotted key for ranges. Boolean false and integer 0 are active criteria; empty or whitespace-only scalars and ranges with no filled bounds are ignored. Criteria for unknown, inaccessible, disabled, deleted, or non-filterable custom fields return 400 and name the rejected keys. A malformed value for a usable custom field returns 422.

Examples: filter[customFields.invoiceReference]=INV-42, filter[customFields.capacity][from]=10, and filter[customFields.capacity][from]=10&filter[customFields.capacity][to]=20. Custom fields do not participate in search.
