Universal containers (uc) uses salesforce to create and manager accounts and opportunities. with salesforce being the master of records, the opportunities on existing accounts are required to be updated with product usage statistics from an on-premise usage tracking system that is capable of participating in contract-first integration. which three steps should the integration architect consider given that uc does not want any custom development in salesforce? (a) create a workflow outbound message during opportunity creation and provide the opportunity id and session id to the remote system(b) use a rest api callback to update the opportunity record with the product usage data from the remote system(c) create a process builder outbound message during opportunity creation and provide the opportunity id and session id to the remote system(d) use a soap api callback to update the opportunity record with the product usage data from the remote system(e) generate a partner wsdl in salesforce and provide it to the remote system to create a client stub
