Who is a bill approver?
You can assign approvers to a bill that requires one or more mandatory approvers. When you apply an approval policy to a bill object, you can designate specific approvers (including the sequence of approvals) with /v2/SetApprovers.json.
Note: To replace an approver assigned to a bill or to change the sequence of approvals, remove all approvers assigned to the vendor credit (with /v2/ClearApprovers.json) and then designate specific approvers (including the sequence of approvals) with /v2/SetApprovers.json.
