Database systems and methods of batching data requests for application extensions

Database systems and methods are provided for providing record data to an application extension associated with a native application at a client device. One method involves a cross-platform service at the client device receiving a plurality of requests for data for one or more records at the database system from the native application, aggregating a subset of the plurality of requests into a batched request, providing the batched request to the database system over a network, receiving a batched response to the batched request from the database system over the network, and for each request of the subset of the plurality of requests of the batched request, mapping a respective data set of the batched response to a respective request and providing the respective data set to the application extension in response to the respective request via the native application.
