Export size and background processing
You can export up to 10,000 contacts to Salesforce in a single job. Exports of up to 150 contacts process in real time. Larger exports run in the background in 20 batches - you can keep working while the job runs. If your selection exceeds 10,000 contacts, Lusha exports the first 10,000 and leaves the rest marked Not exported, so your next run picks up automatically. The 10,000-record cap is a Salesforce platform limit and cannot be changed.Step 1: Connect Salesforce to Lusha
Log in to your dashboard
Select Salesforce in Integrations
Choose your environment and connect
Sign in to Salesforce
Continue to field mapping

Step 2: Set up field mapping
Field mapping tells Lusha which Salesforce fields to populate when you export a contact. You can map fields for three record types: Lead, Contact, and Account.- Each Lusha field on the left maps to a Salesforce field on the right.
- You can change any default mapping by selecting a different Salesforce field from the dropdown.
- Toggle on Allow Override if you want Lusha to update fields that already have data in Salesforce.

LeadStep 3: Add predefined value fields (optional)
Predefined value fields let you automatically populate a Salesforce field with a fixed value every time a contact is exported from Lusha.Select the record type
Add a predefined value field

Choose the Salesforce field
Enter the fixed value

Step 4: Set up conditional field mapping (optional)
Conditional mapping lets you trigger additional field updates when an email or phone field is enriched - useful for lead routing workflows.Open Advanced mapping
Define the condition
Apply and save

Step 5: Test your mapping
Before saving your configuration, click Test Mapping at the bottom-right of the screen. Lusha will create and immediately delete a dummy Lead, Contact, and Account in your Salesforce environment to verify that your settings are valid. If the test passes, the Test Mapping button turns green and you can click Save Changes. If it fails, Lusha will return the matching Salesforce error to help you fix the configuration.Account export preferences
(Available for Admins only) In the integration settings, you can control which Salesforce object types your team can export to. When the Account creation toggle is off, users can only export contacts to existing Salesforce accounts - they cannot create new accounts from Lusha.
Autocomplete
The autocomplete setting matches the account name in Lusha to an existing account name in Salesforce as you type, saving time during manual exports.
Sync opt-out contacts to Salesforce
(Available for Admins only) Lusha can automatically sync a contact’s opt-out status to Salesforce, so your CRM data stays consistent with Lusha’s suppression list without any manual list management.Open Salesforce integration settings
Enable the sync
Choose the target field
Troubleshooting: Salesforce authentication issues
My team is being logged out of Salesforce / lost Salesforce authentication
If your team members see a “reconnect to Salesforce” prompt when trying to export, or find themselves force-logged out of the integration, this is caused by an expired OAuth token. Salesforce OAuth sessions have a finite lifetime - when the token expires, Lusha loses its authorisation to push records and prompts the user to reconnect. This is a Salesforce session behaviour, not a Lusha bug. Each affected team member needs to reauthenticate individually. To reconnect your Salesforce account:Open Salesforce integration settings
Reconnect Salesforce
Sign in and confirm permissions
Connection restored
Contact imported from LinkedIn is missing fields in Salesforce
If a contact’s LinkedIn URL, website, country, city, industry, or annual revenue isn’t populating in Salesforce, the field isn’t included in your current mapping or the data wasn’t available at the time of export.Open Field Mapping
Check and add missing fields
Enable Allow Override if needed
