Identifying OutboundSync data in HubSpot
When to use this guide: Use this guide when configuring or validating CRM integration behavior.
There are two ways of identifying records (Companies, Contacts, Activities) that have been created or updated by OutboundSync in HubSpot.
HubSpot source properties are best for identifying records created by OutboundSync. If a HubSpot source uses Contact handling: Update Only, OutboundSync may update an existing contact without becoming that contact’s original source. In that case, use OutboundSync activity records or custom contact properties, such as Last update source, to identify contacts updated by OutboundSync.
Identifying OutboundSync by app name
Section titled “Identifying OutboundSync by app name”OutboundSync’s official app name in HubSpot is OutboundSync. You will find this used in various menus and sections like the Record Source Detail 1 property**.**
This is most useful when you want to find contacts or companies originally created by OutboundSync.
Identifying OutboundSync by app ID
Section titled “Identifying OutboundSync by app ID”OutboundSync’s official app ID in HubSpot is 1738916. You will find this used in more technical places like the Original Source Drill-Down 2 property.
This identifies OutboundSync as the original source detail for records created through the app. Existing contacts updated by Contact handling: Update Only usually keep their original source.
HubSpot source vs sales engagement platform source
Section titled “HubSpot source vs sales engagement platform source”HubSpot’s Record source answers who created the contact. It does not tell you which sales engagement platform (SEP) produced the outbound activity. When Record source shows OutboundSync — or stays on a HubSpot form / offline source for a contact that already existed — use the signals below to tell Instantly, Smartlead, HeyReach, and other SEPs apart.
| Question | Use | Notes |
|---|---|---|
| Did OutboundSync create the contact? | Record source detail 1 equals OutboundSync, or Original source drill-down 2 equals app ID 1738916 | Contacts created earlier by a HubSpot form keep that original source even after OutboundSync syncs activity. |
| Did OutboundSync update a pre-existing contact? | Last update source is known | The property value is the last synced event type (for example EMAIL_SENT), not the SEP name and not the string OutboundSync. |
| Which SEP produced the activity? | Timeline/app event Sales engagement platform, and/or custom property Last app URL | Instantly URLs contain app.instantly.ai; HeyReach app.heyreach.io; Smartlead typically app.smartlead.ai. Some platforms (for example EmailBison) may leave Last app URL empty. |
On a contact timeline, open an OutboundSync app event and check Sales engagement platform (values such as instantly, smartlead, or heyreach). That field names the SEP for that activity even when HubSpot Record source only shows OutboundSync. See Contact timeline events in HubSpot.
For list and filter recipes — including Last app URL contains filters — see Filtering and building contact lists. For the full custom-property reference, see HubSpot properties updated by OutboundSync.
