Abstract: Systems and methods are provided for synchronizing data. The systems and methods include operations for: storing a synchronization entry for a messaging application feature, the synchronization entry comprising a last update timestamp associated with a first update to content of the messaging application feature received from a first source; receiving a second update to the content of the messaging application feature from the first source; determining that the second update was received within a write window of the last update timestamp; in response to determining that the second update was received within the write window of the last update timestamp, preventing updating the last update timestamp; and sending the first update and the second update to a client device in response to receiving a synchronization request from the client device based on the last update timestamp.

Abstract: The subject technology requests a group identifier (ID) based on an item identification indicator to an extension application programming interface (API). The subject technology requests, using the extension API, a set of augmented reality (AR) content generator IDs, based on the item identification indicator, to a shopping AR content generator service. The subject technology receives the set of AR content generator IDs based on a mapping of the item identification indicator to a collection of AR content generator IDs. The subject technology requests, using the extension API, first metadata associated with the set of AR content generators and the item identification indicator to the shopping AR content generator service. The subject technology requests, using the extension API, a set of products based on the first metadata. The subject technology generates, using the extension API, a group ID based on the set of products. The subject technology receives the group ID.
