Example methods, apparatuses, and systems are presented that allows a user to make a secure purchase online, directly through accessing an online advertisement and without being redirected to multiple, cumbersome webpages to process different pieces of information to complete the transaction, while still leveraging existing e-commerce entities, such as existing payment platforms and existing ad/content networks. The present system includes a commerce ads engine (CA engine) that interfaces with the user through an app associated with the CA engine, a tokenization platform for authentication of the user, and a merchant providing relevant offer and check out information about a product being advertised in an online ad. The present system integrates new information embedded into online advertisements that interfaces with the CA engine and allows for the user to reliably provide authentication while purchasing the desired product, and without accessing or being redirected to multiple websites as is conventionally done.
