# List invoices

GET https://api.caresquareapi.com/api/public/v1/invoices

Paginated list of invoices for the plan manager. Optional filters: participant_id, provider_id, claim_status, approval_status, invoice_number. Paginate with limit/offset, or pass after for a stable id-ascending cursor (start with after=0, then pagination.next_cursor). Requires X-Plan-Manager-Id header.

Reference: https://docs.caresquareapi.com/api-reference/invoices-and-claims/invoices/list-invoices

## Authentication

- `Authorization` header (bearer token, required) — API key issued for your account. Send as Bearer token in the Authorization header.
