How to Fix HubSpot Salesforce Integration Suspension Errors
When your Salesforce integration stops syncing, HubSpot will suspend the connection to protect your CRM data. This guide explains why suspensions happen and shows you how to fix the most common errors so you can safely resume data sync between the two systems.
Below you will find the main suspension types, how to troubleshoot them, and what to do inside both platforms to restore a healthy integration.
Understanding HubSpot Salesforce Integration Suspension
The integration between Salesforce and your marketing platform can be suspended when repeated sync failures occur. HubSpot will automatically pause the connection to prevent data loss, duplication, or corruption.
Typical suspension causes include:
- API access or authentication issues
- Sync filters blocking large groups of records
- Deleted or changed fields and mappings
- Salesforce validation rules rejecting updates
- Permission or sharing setting changes in Salesforce
Before you attempt to resume the integration, you must identify and correct the specific issue that caused the suspension.
Where HubSpot Shows Salesforce Suspension Errors
You can view suspension details directly from your integration settings. This section summarizes what you will see and where to click.
- Sign in to your account.
- Navigate to your connected apps or Salesforce settings.
- Locate the Salesforce integration status banner.
- Click the error or warning link to open detailed suspension information.
The error message provides the best starting point. Use it to learn which type of HubSpot integration issue triggered the suspension and which record types are affected.
Common HubSpot Salesforce Suspension Types
Most suspensions fall into several repeatable patterns. The steps below outline how to troubleshoot each type so you can cleanly resume syncing.
1. HubSpot Cannot Connect to Salesforce (Authentication Errors)
If the integration cannot authenticate, the sync will pause until access is restored.
Typical causes include:
- Changed Salesforce passwords or tokens
- Disconnected integration user
- Revoked OAuth permissions or connected app changes
How to fix:
- Open your Salesforce integration settings in HubSpot.
- Look for prompts to reconnect or reauthorize.
- Log in with the dedicated integration user in Salesforce.
- Confirm the connected app still has API rights and is not blocked by login IP ranges or session policies.
- Save and test the connection, then check that sync resumes.
2. HubSpot API Limit or Salesforce API Limit Issues
Heavy data loads can reach API limits and trigger errors, which may result in a suspended sync if the problem persists.
To troubleshoot:
- Review the Salesforce system overview to see current API use.
- Check app usage to identify which systems consume the most calls.
- Confirm that batch jobs or imports are not overwhelming the integration.
Recovery steps:
- Wait for daily API limits to reset, if the spike was temporary.
- Reschedule large data operations outside of peak sync times.
- In HubSpot, reduce unnecessary sync operations by narrowing filters or disabling unused object syncs.
3. HubSpot Field Mapping and Deleted Field Errors
If a mapped Salesforce field is deleted, renamed, or its data type is changed, the integration may fail when trying to update that field.
Key symptoms:
- Errors referencing specific field API names
- Contacts, companies, or deals stuck in sync with repeated failures
How to fix:
- Identify the field name from the error details in your HubSpot integration logs.
- In Salesforce, verify whether that field still exists and confirm its data type.
- Open field mappings in the integration settings.
- Update the mapping to point to a valid Salesforce field with a compatible type.
- Remove obsolete mappings that no longer have a matching field.
After updating mappings, re-run sync on failed records or restart the suspended sync, then monitor for errors.
4. Salesforce Validation Rule Blocking HubSpot Updates
New or changed Salesforce validation rules can reject updates coming from the integration. When enough records fail, the system can suspend the connection.
What to review:
- Recent validation rules added or edited in Salesforce
- Record type specific requirements for leads, contacts, accounts, or opportunities
- Custom logic that references fields populated by HubSpot
Resolution steps:
- Open one of the failed records in Salesforce to reproduce the error.
- Check the validation error message shown to users.
- Adjust the rule so that valid sync data passes. Options include:
- Excluding the integration user from the rule
or - Making conditions less restrictive
or - Ensuring the required fields are mapped and populated correctly
- Save validation rule changes.
- Return to your HubSpot integration and retry sync for failed records.
5. HubSpot Sync Filter and Inclusion List Problems
Sync filters define which records are eligible to move between systems. Incorrect filters can cause unexpected suspensions when thousands of records suddenly qualify or become ineligible.
What to check:
- Current inclusion lists or criteria for leads, contacts, and accounts
- Lifecycle stage or status filters that changed recently
- Mass updates to properties that affect filter logic
How to fix:
- Open object sync settings in HubSpot for the affected object type.
- Review sync filter conditions line by line.
- Adjust criteria to match your true business rules.
- Save changes and confirm that the expected number of records is set to sync.
6. Permission and Sharing Issues Between HubSpot and Salesforce
The integration user must have enough rights in Salesforce to read and write synced records. If permissions are downgraded, updates can fail until suspension occurs.
Verify:
- Profile and permission set assignments for the integration user
- Object-level CRUD permissions for each synced object
- Field-level security on all mapped fields
- Sharing rules or role hierarchy that might hide records from the integration user
Once permissions are restored, return to your integration settings and resume the sync.
How to Safely Resume the HubSpot Integration
After resolving the root cause, you can restart syncing. Use the steps below to avoid repeating the same suspension.
- Open the Salesforce integration settings.
- Confirm that no critical errors remain in the error log.
- Click the button or link to resume or re-enable the sync.
- Monitor the integration dashboard for new failures during the first few sync cycles.
If the same error appears again, review the relevant section of this guide and confirm that mapping, validation, or permissions are fully aligned on both sides.
Best Practices to Prevent Future HubSpot Suspensions
To minimize future interruptions to your Salesforce connection, implement these ongoing practices.
Governance Tips
- Use a dedicated integration user in Salesforce with stable credentials.
- Document your mapping and sync rules so admins know which fields are critical.
- Review validation rules and field changes with your marketing operations team before deployment.
Monitoring Tips
- Check integration error logs weekly for new patterns.
- Limit large imports during business-critical syncing windows.
- Schedule periodic audits of sync filters and inclusion lists.
