If you detect a problem with a property version while its activation is still PENDING, use this operation to cancel it. Make a DELETE request on the activationLink you get from the Activate a property operation's response. Once you DELETE the activation, it no longer appears in the list of activations, but you can still access it individually. If there are unexpected problems with an activation that goes live before you're able to cancel it, you often have a one-hour window to quickly fall back to a previous activation. See Activate or deactivate a property for details.
