* Page referenced in this article: marketing sources and campaigns page.
A Source identifies where a lead came from. Sources are the foundation for attribution, pipeline reporting, and Marketing ROI in LeadCenter.
You can also reach this page from Marketing → Sources in the left sidebar.
Common reports powered by Sources include:
| Concept | What it answers | Example |
|---|---|---|
| Source | What top-level channel did the lead come from? | Google Ads, Facebook, Radio, Seminars, Referral |
| Campaign | Which specific effort under that Source generated the lead? | Retirement Webinar Q4, Brand Search, Atlanta Seminar |
| Medium | How did the lead actually reach LeadCenter? | Website form, phone call, email redirect, Text-in keyword |
Campaigns use the same form as Sources. The difference is that you select a Parent Source.
The new item appears as a child Campaign under the parent Source.

Most capture methods are tied to a Source on their own settings page.
Note: the Source form does not have a Mediums multi-select field. Mediums are determined by how each capture method is configured.
Go to Marketing → Sources, or open the Sources page directly.
Use the same Add source button and select a Parent Source in the form.
The Source form does not include a Mediums field. Mediums are determined by the capture method, such as phone numbers, forms, email redirects, or Text-in keywords.
