"We're not interested in building a payments business. We're interested in trying to build the best possible experience."

Marcus, who is Facebook's vice president of messaging products, spoke to CNBC in an interview from the Code Conference in Rancho Palos Verdes, California. He was formerly president of PayPal.

The app has just north of 600 million active users, said Marcus. In March the company announced that it would allow person to person debit card payments through Messenger.

He explained that the Facebook strategy is to elevate the communication experience through the app. Now users can make phone and video calls through Messenger. "We'll continue innovating around how you can upgrade from text to other things, but we think that text is still going to be the primary communication media for a long time," he said.
