Leads
Bulk create/update leads
Bulk import leads from a JSON array (max 5,000 per request). Processed in batches of 1,000 with up to 10 concurrent batches.
Options:
- skipDuplicates (default true): When true, existing leads (by email) are skipped. When false, existing leads are updated with the new data.
- dataCleanup (default true): Normalize emails, phone numbers, LinkedIn URLs, and strip special characters from names.
- tag: Optional tag to apply to all imported leads.
Each lead object must include email. Standard fields (firstName, lastName, companyName, etc.) are mapped automatically. Any unrecognized keys become custom fields.
