Quantum Vault

Quantum Vault is the remote storage version of the Quantum Gateway module. Quantum’s server stores credit card details for rebilling rather than storing them in your WHMCS database. This reduces PCI compliance requirements and completely negates many risks.

Adding the Quantum Vault Payment Gateway

To set up the Quantum Vault payment gateway in WHMCS:

  1. Go to Configuration () > Apps & Integrations or Addons > Apps & Integrations.
  2. Click Quantum Vault.
  3. Check Show on Order Form to display this payment method in the Client Area during checkout.
  4. Enter your Quantum Vault credentials.
  5. Click Save Changes.

Test Mode

This payment gateway module does not include test mode.


“Missing the following: Ending /QGWRequest, Ending /Authentication, Ending /GatewayKey”

If you see this at Billing > Gateway Log for a failed payment attempt, it indicates that the provided Vault Key value contains an ampersand. You will need to change this value in both the Quantum Vault dashboard and in WHMCS to omit the ampersand.
