# UTM Codes

UTM codes can be attached to the platform link to include certain information about the newly registered user.

Platform supports 3 code types:

1. **utm\_source** — the source of the traffic
2. **utm\_medium** — the medium of the traffic
3. **utm\_campaign** — the campaign of the traffic. It assigns a certain billing plan to the newly created account.

**Link with atached codes should look like this:**

* <https://app.docstudio.com/>?utm\_source={source}\&utm\_medium={medium}\&utm\_campaign={billing\_plan\_UUID}

*{source}*, *{medium}*, and *{billing\_plan\_UUID}* should be replaced with needed values.

{% hint style="info" %}
If there is a default billing plan on the instance, it will be overridden by the value passed in the utm\_campaign code. User should complete the registration on the platform via such link for codes to take effect.
{% endhint %}

**If you want to add these codes to an envelope initiation link, it should look like this:**

* <https://app.docstudio.com/shared-envelope/create>?code=09c8a0ce572c40e196b2f1782b7ebe01\&redirectUrl=\&utm\_source={source}\&utm\_medium={medium}\&utm\_campaign={billing\_plan\_UUID}

**For an envelope initiation iframe, it should look like this:**

```
<iframe width="100%" height="100%" src="https://app.docstudio.com/shared-envelope/create?code=09c8a0ce572c40e196b2f1782b7ebe01&redirectUrl=&utm_source={source}&utm_medium={medium}&utm_campaign={billing_plan_UUID}" frameborder="0"></iframe>
```
