You will be notified via email if your credit card payment fails. We have a 30 day grace period intended to allow you plenty of time to sort out any payment failures.
In the event this grace period expires, you will not lose connection to the LaunchDarkly service. Your users will continue to receive the correct variations for their flags. The impact is that you will hit a paywall when trying to log into your LaunchDarkly account. This will prevent your team from being able to manage LaunchDarkly resources from the UI, so if you need longer to sort out your payment issues it is important to reach out to our support team as soon as possible so that we can accommodate you.
Please contact support@launchdarkly.com if you have any concerns or require any additional support or information regarding a payment failure. We're here to help.
