In order for Requests for quotation (RFQ) flow seamlessly to and from Guided Buying, end points must be properly configured in Guided Buying and in the Ariba Network buyer account. 

Steps to configure endpoint in guided buying are as follows:

1. Click Admin > Endpoint configuration on the Tactical Sourcing section
2. Enter the name and shared secret password for the endpoint in the Endpoint name (typically "GBEndPoint") and Endpoint password fields.
3. Click Submit

Note: These values need to match the endpoint that's configured in your Ariba Network buyer account exactly. Both values are case sensitive.

Steps to configure endpoints in the Ariba Network buyer account are as follows: 

1. Log in to the Ariba Network buyer account
2. Click Administration > Configuration > Business End Points (cXML and OData Setup) (if the Business End Points option is not on the list, that means the Enable end point support entitlement in the Ariba Network buyer account is not enabled) 
3. Setup the end points according to the information on the Additional Information section
4. Click Administration > Configuration > Business End Points (cXML and OData Setup) > Configure Document Routing
5. Select the end point for the following document types:
   • Request for Quotations: S4EndPoint
   • Quotes: GBEndPoint (if the customer is already using quote integration, set it to Request for Quotations Origin)

Ariba & Default End Point IDs (no need to change)

• Set Select an integration type to cXML
• Set Profile Url:  
  • for US data center:  https://s1.ariba.com/Buyer/cxmlchannel/{ANID}
  • for EU data center:  https://s1-eu.ariba.com/Buyer/cxmlchannel/{ANID}
• Check "Yes, I want to receive documents through the POST method instead of through the cXML GetPending method."
• Set the Shared Secret for the "Default" and "Ariba" End Point IDs
  • Default - this is S4/AN integration
  • Ariba - this is for SSP/AN integration

Create two new end points (ALL shared secrets must match!):
