Cancelling Out For Signature Agreements via v6 Rest API

Hello; we're finalizing some conversions from the SOAP api to the REST API for Adobe but I don't seem to be able to cancel a document via the REST api once its out for signature. We usually had done then when the document was being updated in our system to make sure we only use the latest and we don't want to rely on the signers to cancel first. Is there a way to do that still?
