cancel_letter
shallowcom.printandmailcompany/printandmailcompany · Verify this server
Use this when the user wants to stop a letter they created here: cancels a draft, or a paid letter that has not gone into production yet, and returns the amount to the user's credit. Letters already printed or posted cannot be recalled. This cancels our letter, not a contract the user has with someone else (for that, compose_letter writes the cancellation letter). Ask the user before cancelling. Needs the user's account.
