HubSpot Activity Syncing
HubSpot Activity Syncing automatically sends supported activity data from Seamless to HubSpot so your engagement history stays up to date. This article explains how to enable syncing, review activity import mappings, understand sync statuses, and troubleshoot common issues.
Brand refresh in progress
We recently launched a new brand, so some images and videos may differ from what you see in-product. All workflows and guidance remain accurate while we update visuals.
HubSpot Activity Syncing allows Seamless to automatically sync activity data to HubSpot so your engagement history stays current and consistent across platforms. Once this feature is turned on, syncing happens automatically in the background and includes all supported activity types.
This is an all-or-nothing setting, which means activity syncing cannot be customized by activity type. It is either fully enabled or fully disabled.
How Activity Syncing Works
When Activity Syncing is enabled, activities from Seamless are automatically pushed to HubSpot without any manual action required. Syncing runs in the background and includes all supported activity types by default.
Because this process is automated, users do not need to manually select activities or trigger the sync themselves.
How to Enable Activity Syncing
To turn on Activity Syncing, go to Settings, then open CRM Setup. From there, select the Activity Syncing tab, toggle on Enable auto-import of activities, and click Save.
Once saved, syncing will begin automatically.

Activity Import Mapping
Before syncing activities, it is important to review how your Seamless fields map to your HubSpot fields. This helps make sure activity data is sent to the correct place in HubSpot and keeps your records accurate.
To update these settings, go to CRM Setup, open Activity Syncing, and scroll down to Activity Import Mappings.
Each row in this section represents a field mapping between Seamless and HubSpot. For example, you may map:
- Website in Seamless to the Website field in HubSpot
- Website Domain to the Domain field
- Phone to the Phone field in HubSpot

Each mapping also includes the option to Add a Custom Mapping. This allows you to create additional mappings for custom HubSpot fields when needed.

It is also important to note that only HubSpot fields with the proper write permissions will be available for mapping.
Activity Page Enhancements
Once Activity Syncing is enabled, new columns will appear on the Activity page so users can quickly see whether an activity was sent to HubSpot and what its current sync status is.
These added columns may include:
- HubSpot Activity Synced
- Shows the current sync status for the activity
- HubSpot Activity Synced Date
- Shows the date and time of the last successful sync
- CRM Indicator
- Displays the connected CRM, such as the HubSpot icon
From the Activity page, you are able to sync Connect activity to your CRM individually through the icon in the CRM column.
If other CRM or sales engagement tools are also connected, you may see additional sync-related columns as well, such as:
- Salesloft Activity Synced
- Salesloft Activity Synced Date
These columns give users better visibility into what has synced successfully and what may still need attention.
Understanding Sync Statuses
The HubSpot Activity Synced column will display one of the following statuses:
- Synced
- The activity was successfully sent to HubSpot
- Syncing…
- The sync is currently in progress
- Sync Failed
- The sync attempt was unsuccessful and may need to be reviewed
Reviewing these statuses can help users quickly understand whether activity data is flowing properly into HubSpot or if troubleshooting may be needed.
Important Things to Know
Once Activity Syncing is enabled, the process is fully automatic. There is no need to manually push or pull activities between Seamless and HubSpot.
A few important things to keep in mind:
- Activity syncing is all or nothing
You cannot choose specific activity types to sync. Once enabled, all supported activities will be included. - Field mappings matter
If your mappings are incomplete or incorrect, activity data may appear in the wrong place or fail to sync properly in HubSpot. - HubSpot field permissions are required
Any HubSpot field used in your mapping must have the proper write access in order to work during syncing.
Reviewing these settings carefully before enabling sync can help prevent missing data, mapping issues, and unexpected results in HubSpot.
Troubleshooting Tips
If activities are not syncing as expected, there are a few quick things to review first:
- Confirm Activity Syncing is enabled
- Go to CRM Setup and make sure Activity Syncing is turned on.
- Review your field mappings
- Check that your mappings are accurate and complete so activity data is flowing into the correct HubSpot fields.
- Look for failed syncs on the Activity page
- If you see a Sync Failed status, that can help identify which activities need attention.
- Verify your HubSpot connection
- Make sure your HubSpot integration is still connected properly in Seamless.
Checking these areas first can help you quickly identify the most common causes of activity sync issues.
Summary
HubSpot Activity Syncing helps reduce manual work by automatically keeping activity data aligned between Seamless and HubSpot. With the right mapping setup and clear visibility into sync status, users can manage engagement data more confidently and keep their CRM records up to date.
