From the Preview & Publish tab of any P2P Campaign page you will find several ways to share your page including sharing the unique URL for the donation page, the QR code, and several Widget Embedded Codes. You can learn more about sharing your pages in this article Sharing DonorView Pages & Links.
If your P2P campaign is linked to an event and you would prefer that participants purchase tickets prior to setting up their fundraising pages, share the links for your event page instead. The URL and QR codes on the P2P campaign page go directly to the portal.
For the Widget Embedded Codes, these allow you add progress updates on fundraising, participants and teams. You can copy and embed these into your own website so that your website visitors can see how your campaign is progressing and who the leading fundraisers and teams are. Below is an example with the Participant List Widget embedded.
