Imports are typically performed via XML in a pre-defined structure using an HTTP post. For systems which are not able to support a direct post, it is also possible to upload orders in a CSV (comma-separated) or a TSV (tab-separated) format. Built-in formats have been defined for both Amazon WMS integration and eBay WMS integration.
There is no limitation to the number of import formats which can be used for imports from a single channel or organisation as import source, although in practice, only a single import should suffice.
As data is imported, it is possible to apply arbitrary field by field transformations, both to convert data from one format to another, and to apply business-specific rules.
