USD invoices use US bank details (`aba`, `swift`); EUR invoices use an IBAN. The account details are specific to your organization: do not reuse another firm's. At most 30 requests a minute per organization. **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/{invoiceId}/payment-instructions 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 invoices](https://docs.hyperprop.com/platform-api/billing-and-invoices/list-invoices.md) - [Build your own CRM on Hyperprop](https://docs.hyperprop.com/guides/build-a-crm.md) - [Continuous futures](https://docs.hyperprop.com/guides/continuous-futures.md) This documentation is built and hosted on [Mintlify](https://mintlify.com), a developer documentation platform.
