Create a connected organization.

Optionally pass currency_code to set the connected organization's balance currency. Supported values are USD, EUR, and GBP. If omitted, the balance currency defaults to USD.

Optionally pass a kyb_prefill object to forward KYB (Know Your Business) details you have already collected for the end client. When provided, these values prefill the end client's onboarding form; the end client still reviews, edits where needed, and submits the form. Every kyb_prefill field is optional, but any value provided is validated. Malformed KYB details (for example an unsupported country_code or a malformed website_url) return a 400.
