Which Salesforce fields are updated
Last updated July 8, 2025
When OutboundSync is connected to your Salesforce instance, we have the option to create a group of custom fields on both the Lead and Contact 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.
