# Referral Program Campaign Manager Talon.One uses three terms in Referral program : * **Advocate**: the customer or user who recommends your product. * **Friend**: the new customer acting on the advocate's recommendation. * **Referral Code**: the code that the advocate gives to their friend Referral Program can be enabled by selecting Referral feature in any Campaign. This feature enables Referral feature effects in Rule Builder. * **Condition**: "Referral Code is Valid", which makes sure the code hasn't been used already. * **Effect**: "Redeem Referral Code" which marks the referral code as used. * **Effect:** "Create a Referral Code" which generates a code for this user to give to others. On Referral Code Generator Setting page, Campaign manager provides various options to customize generation of referral code. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
