# Unapply an authorisation rule

Deactivates an authorisation rule. This will result in all card transactions **not** being evaluated against this rule.
The rule still [exists](/api-reference/spend-controls/spendcontrolsruleslist) and can be [applied](/api-reference/spend-controls/spendcontrolsruleapply) again.
