How To Link Your Donation Page to Your Pledge Page
Go to your personal fundraising page (hosted on the charity's website, not in Charity Miles).
Click the share icon on the bottom of your screen and copy the page URL.
In Charity Miles go to Settings > Pledge Drive and click the pencil icon in the upper right to edit your pledge drive settings.
Paste the link into the space that says “personal donation link”. This will allow your donors to donate directly to your charity.
Now when your friends pledge to sponsor you, they will be redirected to your donation page to fulfill their donation.
