This is a Common Lisp library providing access to the Moneris payment processing ( HTTPS POST API. The basic use pattern is to create a merchant-token with your store's information (API token, store ID, and the access URI you received from Moneris), then call the 'process' function with the merchant-token and a transaction (you can create transactions with the 'purchase,' 'correction,' and 'refund' functions provided - see their documentation strings for details). 'process' returns multiple values: txn-id - transaction ID code - numeric response code code-description - response code description message - message returned in response response-xml - parsed XML of response response-string - raw XML response string response-xml contains all the information you need to generate a client receipt/invoice; consult the Moneris API documentation ( to learn about its format and fields. The file test/moneris-test.lisp provides examples using the Moneris API test server. cl-moneris was originally authored by Wade Humeniuk. It was converted and released by Vladimir Sedach <> cl-moneris is available under the ISC (BSD) license, except for the unit tests, which are released into the public domain.
