If you are integrating a peer-to-peer fundraising campaign with Salesforce, Soapbox will save the Fundraiser to fields on the Lead record created for a donation processed on a given Fundraiser's page. These should then map to the Opportunity object. This occurs automatically if the expected fields exist in your Salesforce instance.
If this is not occurring in your Salesforce instance, you may need to add these four fields to the Lead object and Opportunity object and then map them from the Lead to the Opportunity object. When defining the API Name, enter only the string proceeding __c. Salesforce automatically adds __c to custom fields:
