3. If you want to generate custom links with the link format above for existing affiliates, kindly check this box and remember to press **Save** so the system can start generating for you. UpPromote will send you an email to inform you about a successful or failed (if any) custom link generation.

### 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;
