1.Sync via API
The admin is required to go to “WeChat Work Admin Console” -> “Management Tools” -> “Contacts Sync” to enable Contacts Sync and set the permissions for Contacts.
2.Sync by other means
If WeChat Work is activated through Tencent Exmail, Tencent enterprise account or RTX, Contacts Sync is enabled automatically by default. You can also authorize a third-party service provider to manage your contacts. After Contacts Sync is enabled by either of the above methods, WeChat Work Contacts will read contacts of appropriate products. These contacts cannot be edited in WeChat Work by default unless “Allow Edit in WeChat Work” is enabled.
