You open your WordPress dashboard, find a payment setting, and discover it asks for details you do not have. Pause there. Before connecting Cybersource, check that your site, payment plugin, and provider account are ready for the same setup.
Check the WordPress payment plugin
In WordPress, identify which plugin or checkout tool currently handles payments. Look in its documentation or payment settings for explicit support for Cybersource; a general mention of credit-card payments is not enough to confirm compatibility. If you do not see Cybersource listed, check with the plugin provider before installing another payment extension.
Also note the plugin’s name and version, along with your WordPress version. These details help you compare your setup with the instructions and support information you find. Plugin menus and available payment options can differ, so avoid following steps written for a different tool.
Gather account access first
Sign in to the Cybersource account intended to process payments for this site, and confirm you can access its payment configuration information. The exact credentials and labels your plugin requests depend on the integration it supports, so use the plugin’s Cybersource instructions to identify what you need. Do not guess at fields or substitute login details for payment credentials.
Check whether the setup offers a test or sandbox environment as well as a live environment. Sandbox credentials and live credentials serve different purposes; keep track of which set you are using. Before moving on, write down the plugin name, account environment, and any unanswered questions so you can check your setup against the right documentation.
