A WordPress checkout may look familiar while its payment settings differ completely from another site’s. The plugin you use determines where Cybersource is configured and which account details it asks for. Treat the plugin’s instructions as the map, and check each screen against your own site before moving on.
Find the right payment settings
Open the dashboard for the plugin that manages your checkout, then find its payment or gateway settings. Choose Cybersource only if the plugin lists it as a supported provider. If the option is missing, do not try to create a connection by pasting credentials into unrelated settings; confirm support with the plugin provider first.
Some plugins place payment settings under their own menu, while others put them inside a store or checkout section. Use the plugin’s documentation to match the menu names you see. This is a useful point to confirm that the plugin version and the instructions refer to the same integration.
Enter details for one environment
If the plugin provides separate sandbox and live choices, select the environment you intend to configure before adding its corresponding credentials. A sandbox is a test environment; live mode is for real payment processing. Follow the plugin’s field-by-field guidance for obtaining and entering the required Cybersource details rather than inferring what a field means from its label alone.
Save the settings, then review the selected provider and environment before leaving the page. If the plugin reports an error, record the message and check the account environment, credential pair, and plugin instructions. Avoid sharing credentials in a support request; provide the error text and plugin details instead.
Confirm before taking payments
A saved settings page does not by itself confirm that checkout is ready for customers. Keep live processing off until you have followed the plugin’s recommended test procedure and confirmed how the checkout should behave. If any setting remains unclear, resolve it with the plugin or Cybersource documentation before proceeding.
