PowerExchange for Salesforce uses version 31.0 of the Salesforce API.
Use the Salesforce service URL to configure connections to Salesforce. To use the latest version of the Salesforce API, create an application connection or update the service URL in an existing application connection.
Use the following version of the Salesforce service URL:
https://www.salesforce.com/services/Soap/u/31.0
If the new version of a Salesforce object has a different structure than the previous version of the object, re-import the Salesforce object. After you re-import the object, analyze the associated mapping to determine if you need to update the mapping.
Previously, PowerExchange for Salesforce used version 27.0 of the Salesforce API.
