Thinking of integrating directly with Omnivore? Omnivore exposes a suite of REST APIs to help you send product feeds to us, pull product feeds from us and work with your orders. The REST resources are grouped into the following areas; please choose one to learn more. In general, these resources expect and will produce data in XML format, however it is possible to request data in CSV or JSON formats for certain interfaces. All calls will return a HTTP response code to inform you of success/failure of the action, as detailed in each API definition.
