I need to amend the contract in the Salesforce CPQ from a third party tool. As from the documentation there is a way to do it - https://community.steelbrick.com/t5/Developer-Guidebook/Public-API-Overview/ta-p/5689
Though i have tried to do it using the swagger(as mentioned in the doc). Iam not able to do it. Can someone provide an example to do so.
