You can assign approvers to an approval policy that requires one or more mandatory approvers. In addition, you can set multiple approvers to a policy with /Bulk/Crud/Create/ApprovalPolicyApprover.json.
When you apply an approval policy to a bill or vendor credit object, you can designate specific approvers (including the sequence of approvals) with /SetApprovers.json.
Note: Replacing an approver in an approval policy is a two-step process.
Delete the existing approver from the policy with /Crud/Delete/ApprovalPolicyApprover.json.
Add the new approver(s) with /Crud/Create/ApprovalPolicyApprover.json.
