Arguments
UUID!
required
The spend account (cash balance) the virtual account number belongs to.
UUID
Which of the spend account’s virtual account numbers to document. Defaults to the primary one.
Boolean
Include the account balance on the letter. Omitted by default, since the balance is sensitive.
DateTime
Report the available balance as of the end of this day (US Eastern) rather than the current
balance, and label the letter’s as-of line with that date. Cannot be in the future. Applies
only when displayBalance is true; ignored otherwise.Requires a full RFC-3339 timestamp — a date alone (“2026-07-01”) is rejected. Only the day
the instant falls on in US Eastern is used, so send an Eastern-anchored timestamp: UTC
midnight (“2026-07-01T00:00:00Z”) is 8pm Eastern the day before and reports June 30.
Returns
SpendAccountPdfDocument! — A PDF artifact containing ACH routing and account instructions for funding a spend account’s virtual account number, returned as a base64-encoded string for the client to decode and render or download.
