I am trying to read/update/create Salesforce Opportunities using Salesforce REST API. In Opportunity object, I cannot find any field against Delivery/Installation Status. However when you go to Opportunities section on Salesforce page, there is this field Delivery/Installation Status having 3 options: In Progress, Yet to begin, Completed. Kindly help me how can I use this field when using Opportunity object in API.

Many Thanks
