From setup to steady state: data in the ERP is normalised in the panel, converted into the shape each channel expects and pushed through a queue. Orders coming back from a channel are written into the ERP along the same path.
Three-layer integrations
A transport that talks to the outside system, a format layer that translates between internal data and the external shape, and a mapping layer holding category and attribute equivalents. One channel’s quirks never leak into the others.
In practice: A change or outage on one channel’s API does not spread to the others.
