Lead Sync - Overview

Warning

Deprecation Notice
The Marketing version 202305 (Marketing May 2023) and below has been sunset and the unversioned APIs are going to be sunset soon. We recommend that you migrate to the versioned APIs as well as migrate to the new Content and Community Management APIs to avoid disruptions. See the Migration page for more details. If you haven’t yet migrated and have questions, submit a request on the LinkedIn Developer Support Portal.

The Lead Sync API makes it easy for your customers to automatically collect and sync leads to your platform – saving them time and enabling their sales teams to act on them in real-time. The new API provides access to leads for all marketing use cases, including ads and events as well as the capability to map custom field names to your CRM.
