Which Salesforce fields are updated
Last updated March 13, 2026
When OutboundSync is connected to your Salesforce instance, we have the option to create a group of custom fields on Contact, Lead, and/or Task objects. These fields allow you to track engagement activity and sync details from your Sales Engagement Platform.
These custom fields are helpful for:
- Reporting on outbound activity.
- Triggering automation in Salesforce flows.
- Building lead and contact list views.
- Understanding campaign attribution and engagement history.
Below is a list of all custom fields OutboundSync can create, including their API names and data types.
