Create Custom Fields in Salesforce
In Salesforce, create one custom field for the score and one custom field for the grade on the Lead and Account object, as appropriate depending on what you're scoring. We recommend naming them Radius Score and Radius Grade.
For Radius Score, make sure the field type you choose can receive numerical values. For example, a number from 1 to 100.
For Radius Grade, make sure the field type you choose can receive letter values. For example, A, B, C, and D.
