### Update Custom link&#x20;

If you update the Default affiliate link for each program or modify UTM parameters, this changes the Affiliate link but the Custom link will not be updated accordingly and automatically.&#x20;

In that case, you can click the **Re-sync links** button in the Custom affiliate link settings to update all custom links to follow the latest Affiliate link. We will inform you via the Notification center when the Re-sync process is done.&#x20;
