Conferma Pay Online supports an approval workflow, which allows credit limits to be set at deployer level. Two Approval levels can be configured with the ability to Approve/Reject requests for higher credit limits. The workflow now offers a dynamic feature allowing approval requests to be directed to specific approvers based on the selection of the custom data field.
