# Payload Changes in the QR Code via ETCD CLI

Currently, only the optional fields that already exist can be removed. New fields cannot be added as of now. 

Note: Do not remove the [**mandatory**](/platform/divocs-verifiable-certificate-features-2.0/what-information-goes-into-a-qr-code.md) fields.

### Steps to remove an optional field:

Run the command: vim DDCC\_TEMPLATE.template.

To reflect the change, run the command: ./updateConfigs.sh. It shows "OK OK OK...." This means that etcd has been updated with the new QR Code template successfully.
