The Approval Request / Response messages provide 2-way integration that is used by Unimarket to request approver information from an ERP/Finance system as the approvals are being completed (in real time). When a requisition is created and routed for approval the integration is triggered so that Unimarket asks the external system for the next approver. This process continues until all the approvals are complete.
This integration can be used instead of the Approval Configuration Request if a customer does not want to load approval data into Unimarket or perhaps they have very complex rules in their ERP that they do not want to replicate.
Message examples relating to the integration can be found below:
