Update the calendar for one or more statements.

Notes:

• To function properly, the calendar must be updated no later than two days before the cycle closes.
• The endpoint only works for fixed due date calendars. For other types of calendars, refer to the Calendar management strategies guide.
• This endpoint requires an account token - an access token encoded with a Pismo account ID. Tokens can expire quickly, which can result in a 401 Unauthorized message.
