What type of events does GA Connector send from Salesforce to Google Analytics?

You can configure events from any Salesforce field or object (if you add the necessary settings).

So for example, it will send the event like this when and object with name={ObjectName} object is created:

Category: Salesforce {ObjectName}

Action: Create

Label: (not set)

When a text/date/picklist field with name={FieldName} is updated, GA Connector will send an event like this one:

Category: Salesforce {ObjectName}

Action: Update {FieldName}

Label: {FieldValue}

Or if it’s a number field:

Category: Salesforce {ObjectName}

Action: Update {FieldName}

Label: (not set)

Value: {FieldValue}
