# Set Referral Link Parameters
**GoAffPro** provides you with the option to set parameters for affiliate referral links.
{% hint style="info" %}
The referral link parameters option lets you add UTM parameters to the affiliate referral links. This allows tracking specific information, such as the source, medium, and campaign associated with each referral link.
{% endhint %}
To set parameters for affiliate referral links, go to the **Advanced** section of the **Settings** tab in the GoAffPro admin panel.
Settings > Advanced
Here, go to the Referral Link Parameters section.
Now, enter the parameters you want to set for the affiliate's referral link.
{% hint style="info" %}
When adding the parameters, the **utm\_source**, **utm\_medium**, and **utm\_campaign** parameters should always be used. Whereas, the **utm\_term** and **utm\_content** parameters are optional.
{% endhint %}
After this, click on **Save**.
The parameters that have been set will be added to the referral links of all the affiliates.
Dynamic Referral Link Parameters
**To add dynamic UTM parameters to the referral link of affiliates, you can use the following tags:**
{affiliate\_id}
{name}
{email}
{ref\_code}
