A limit window is a time frame which dictates when usage and amount limits are reset. A card's available balance is reset at the beginning of each limit window.

📘
Limit windows only apply to lodged digital cards.

When issuing a lodged card, you must specify a limit window. We provide four possible limit window options:

Day: Limits reset each day at 12:00am UTC
Week: Limits reset each Monday at 12:00am UTC
Month: Limits reset on the first day of each month at 12:00am UTC
Lifetime: Limits are never reset and apply to the lifetime of the card

If you change the spending limit on a card, the new spending limit will come into effect at the start of next limit window (e.g. if limit window is "Day", the spending limit will come into effect at the start of the next day).

Example: Limit Windows In Practice

If a lodged card is issued with the following parameters:

Amount Limit	Usage Limit	Limit Window
500	10	Day

This means the card can authorize at most 10 transactions per day, spending up to 500 USD in total across those transactions.

Changing this to the following:

Amount Limit	Usage Limit	Limit Window
500	10	Week

the card can authorize at most 10 transactions per week, spending up to 500 USD in total across those transactions.

Finally, if the card has the following setup:

Amount Limit	Usage Limit	Limit Window
500	10	Lifetime

it can authorize at most 10 transactions, spending up to 500 USD in total across those transactions, in its lifetime. "Lifetime" limit windows do not reset.
