If you’re building a new custom gateway, using the signature key is generally recommended for added security. It helps verify request integrity and prevents tampering, especially when handling sensitive payment data. Just make sure to follow the latest documentation for your gateway and keep the key stored securely on the server side.

If your integration method requires signed fields, then you should include and use the Signature Key as part of your payment gateway setup. If you’re unsure which method you are building, you can confirm by referring to the integration type in the CyberSource developer documentation.
