To help you promote your referral program, you can embed the Pages for the Person Referring on your website or install them as a referral widget or pop-up.
As an additional layer of security, however, you have the option to limit this feature's functionality to specific domains.
How To Restrict Embedding to Authorised Domains
→ Navigate to the Settings tab and then select Emails and Domains.
→ In the section titled Authorised Domains, enter the domain URLs you WANT TO AUTHORIZE. Be sure to enter the domains without "HTTPS://" or "HTTP://".
❗️ By default your referral campaigns will be allowed for embedding, and/or as a widget or pop-up, on all website domains. This feature will only restrict embedding after you add authorised domains.
💡 Please note that your website URL may or may not include the prefix "www.". If you are unsure, we recommend adding both versions: example.com and www.example.com.
→ Click Save.
