Abstract: Systems and methods are provided for performing operations including receiving, by a messaging application server from a third-party application server, a request to generate a content item code that is associated with a third-party content item; generating, by the messaging application server, the content item code in response to receiving the request from the third-party application server; causing a representation of the content item code to be displayed; retrieving the third-party content item in response to a messaging application implemented on a user device capturing the image of the representation that is displayed; and enabling an image modification feature of the messaging application using the retrieved third-party content item.

Abstract: In one embodiment, a method includes identifying a plurality of users that are each currently associated with a second computing device that is currently in a discoverable mode; have a commonality among them based at least in part on social-graph information associated with the users; and are currently at or near a common geo-location. The method also includes sending to each of the users a suggestion to interact with the other users based at least in part on their commonality and the users currently being at or near the common geo-location.
