API Documentation for Cart's Multichannel Management

Cart's Multichannel Management has a REST API that allows users to interact with the inventory from their sales channels and their orders. This API can be used to establish integrations that Cart's Multichannel Management may not have at this time or establish a feed from a Vendor to update your quantities or inventory.

At this time Cart's Multichannel Management is not able to take on new API driven projects for our current users. If you have Development resources then they can use our API in order to leverage your expected workflow or missing integration. 

If you are looking to setup a FTP feed from a vendor, that is a slightly different process.  You can review more details here.

At this time all of Cart's Multichannel Management API documentation is located on a secured website:
