# Testing standard payment methods The payment methods with a `standard` [authentication flow](/commerce-api/payments/sources.md#authentication-flow) that Digital River currently supports in our testing environment are Apple Pay, Credit Cards, and Google Pay. Before accepting live payments, you can use the card numbers in this section to test against [success](#success-scenarios-2) and [error](#error-scenarios-2) scenarios. These numbers are only valid in our testing environment. They do not create a real charge or result in a transfer of funds. To conduct the testing, [create a source](https://www.digitalriver.com/docs/commerce-admin-api/#tag/Source/operation/createSources), and use the appropriate data to set the parameters of the `creditCard` hash table. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
