How to Check Payment Processor Credentials

LIMITED RELEASE

Cadmium Payments is available in Scorecard and Expo Harvester.

You can check payment processor credentials when editing a merchant account to ensure the credentials are correct. This option appears on the Edit Merchant Account page.

CADMIUM RECOMMENDS

It is recommended that you check payment processor credentials after a merchant account has been added and before you start collecting payments to ensure the merchant account has been set up correctly.

To check the payment processor credentials:

Log in to the Cadmium Payments platform using your authorized credentials. For more information on how to access Cadmium Payments, refer to the article Accessing Cadmium Payments.

Select the merchant account whose credentials you want to check.
This will launch the Edit Merchant Account page.

Visually confirm that the merchant account credentials have been added completely.

NOTE

The fields on the Edit Merchant Account page will vary depending on the payment processor being used.

Select the gray ‘Check Credentials’ button at the top of the page.
