    • Payment Contract Id - The payment contract can be found in the Verifone Central, under Administration → Payment Contract Providers. The 'Payment Provider Contract ID' listed is the Payment Contract ID required for the plugin configuration. 
    • 3DS Contract  Id - The 3DS Contract ID can be found in Verifone Central, under Administration → 3-D Secure Provider Contracts. Select the 3DS facility required. The ‘3-D Secure Contract ID’ listed is the 3DS Contract ID needed for the plugin configuration.

8. Click the Save button  Integrate opencart Plugin for Verifone_7  to save your configuration. 

9. Create a public key for Secure Card Capture to start accepting eCommerce transactions. You do not need to use this key for the plugin configuration, it simply needs to be created to ensure any card details are encrypted in the browser, so that information can be safely passed from you (merchant) to Verifone. 

To generate a public key from your Verifone Central account follow these steps:

  • Navigate to Administration → Organisations, and select the required organization.
  • Scroll down to the bottom of the page to see the Secure Card Capture area.
  • Click on the Create new public key button.

If some errors are not logged, you can always view the Apache or Nginx logs.

Common errors

  • Not having the currency of OpenCart set to the one that the payment contract supports
  • Entity ID, Payment Contract ID, or 3DS Contract ID don’t match the correct entity for which they were created
  • The cURL verify host and peer option is enable/disable but the host server doesn’t have proper TLS certificates
  • Not having the latest PrestaShop module version installed
  • Make sure that the credentials are correct: Payment Contract ID, User ID, Password, Realm, Entity ID, Client ID, etc.

In most cases, the error may be caused by various PHP errors and/or warnings.

If the error is caused by a request to the Verifone server then the error message received when the request fails is very informative. Here's an example:

{
    "code": 116,
    "details": {},
    "timestamp": 1608705038970,
    "message": "Access is restricted to authenticated users only. The query can't be made without a valid JWT (check the Authorization header of your request)."
}

The above request was denied because the user wasn’t authorized. This is due to an invalid token being present in the Authorization bearer.

This kind of error format will be present on almost all requests that fail and will deliver a concrete error message along with it which in turn will pinpoint the problem precisely.
