First, the OCI shop is set up in your ERP system as an external catalog, including transfer parameters for the shop login. Now when purchasers open the shop via their eProcurement system, the OCI shop opens in a browser window. They can then select WAGO products and put them in their shopping cart. Then, when the order is sent, the shopping cart is transferred via OCI interface to the leading eProcurement system. The shopping cart is transferred to a particular return address (known as a HOOK-URL) of the eProcurement system, normally via HTTP-POST. The items in the shopping cart now appear on the order request screen. After reviewing the order again, purchasers can place the order on channel that suit them.
