To connect AssignmentPro to a vendor on the Ecosystem, a Vendor Hub ID should be added in the vendor's record (system level configuration), on the security tab:
The Vendor's hub ID is unique per the vendor.
In addition, an Instance ID is also required. This ID is unique for the AssignmentPro-Vendor combination. The instance ID should be shared with the vendor, for them to use as a means to identify the AssignmentPro-Vendor combination when sending data.
Each of these IDs should be provided by Equus, from the Ecosystem integration team.
