The check transfer object now contains the front_image and back_image in TIFF format, Base64 encoded. The images are only available in the GET endpoint after the Column issued check is deposited by the payee.

APIs for check issuing are now publicly available. With these APIs it's possible to issue checks, create check returns, and stop check payments. See these docs for detailed information on check processing, timing & notifications, returns, and fraud prevention.

We have added a new type of webhook events ach.outgoing_transfer.noc to notify you ACH Notifications of Change (NOCs) sent by RDFIs for outgoing ACH transfers. See this doc for more information.
