# DeleteResourcePolicyStatement


Deletes a policy statement from a resource policy. If you delete the last statement from a policy, the policy is deleted. If you specify a statement ID that doesn't exist in the policy, or if the bot or bot alias doesn't have a policy attached, Amazon Lex returns an exception.

You need to add the `DeleteResourcePolicy` or `UpdateResourcePolicy` action to the bot role in order to call the API.

## Request Syntax
