Standard object types are objects packaged within Salesforce, such as Account, AccountPartner, and Opportunity.

Custom object types extend the Salesforce data for an organization by defining data entities that are unique to the organization. Salesforce administrators can define custom fields for both standard and custom objects.

When you import a Salesforce object, use a Salesforce login to connect to the Salesforce service. The Developer tool generates a list of objects that are available for import.
