open a deposit account via Unit (banking-as-a-service) — application to customer to account

Steps

1. Create an individual or business application by POSTing to /applications with the applicant's personal or business information; Unit runs KYC/KYB automatically and returns a status of Pending, Approved, or Denied.
2. Poll GET /applications/{id} or handle the application.awaitingDocuments or customer.created webhook to know when the application is approved and a Customer is created.
3. Create a deposit account by POSTing to /accounts with type depositAccount, a relationships.customer link to the approved customer ID, and the desired deposit product.
4. Retrieve the account details (routing number, account number) from GET /accounts/{id} once the account status is Open.
5. Fund the account by initiating an ACH payment via POST /payments/ach or by providing the account and routing numbers to an external sender.
6. Retrieve transactions and balances by calling GET /accounts/{id}/transactions and GET /accounts/{id} respectively.
