You see issued invoices only: `open`, `paid` and `uncollectible`. Drafts Hyperprop is still reviewing, and voided invoices, are never returned (fetching one by ID returns 404 `INVOICE_NOT_FOUND`). Amounts are integers in cents of the invoice `currency`. The list is not paginated: a firm receives a few invoices a month. Filter with `status`. To keep a copy in sync, store invoices by `id` and refresh the ones that are not `paid` yet, since their `amountPaidCents`, `displayStatus` and `paymentState` change as payments arrive. **Access:** read-only and full-access API keys. Dashboard members need view access to Billing & purchases revenue. ## OpenAPI ````yaml https://api.hyperprop.com/platform/openapi.json get /v1/organization/billing/invoices openapi: 3.0.0 info: title: Hyperprop Platform API version: 1.0.0 description: >- REST API for the Hyperprop Trading Platform — provision evaluation and funded trading accounts, manage traders and plans, react to account lifecycle events via signed webhooks, and reconcile billing.

Create, rotate and restrict keys in the dashboard or with the API keys endpoints; an organization can have two active keys, so you can rotate without downtime. A **full-access** key can call every endpoint in this reference. A **read-only** key can call `GET` endpoints (and create a trading stream token); any other request returns `403 READ_ONLY_KEY`. A key with an IP allowlist returns `403 IP_NOT_ALLOWED` from any other address. Each endpoint lists which keys can call it under **Access**. ```` ## Related topics - [Billing and invoices](https://docs.hyperprop.com/guides/billing-and-invoices.md) - [Get an invoice](https://docs.hyperprop.com/platform-api/billing-and-invoices/get-an-invoice.md) - [List billing cycles](https://docs.hyperprop.com/platform-api/billing-and-invoices/list-billing-cycles.md) - [List all billing events](https://docs.hyperprop.com/platform-api/billing-and-invoices/list-all-billing-events.md) - [Download an invoice PDF](https://docs.hyperprop.com/platform-api/billing-and-invoices/download-an-invoice-pdf.md) This documentation is built and hosted on [Mintlify](https://mintlify.com), a developer documentation platform.
