Helper Hooks – Page 61 – Jetpack Developer Resources

action
`jetpack_full_sync_updates`
Tells the client to sync all updates to the server
filter
`jetpack_sync_modules`
Filters the list of class names of sync modules. If you add to this list, make sure any classes implement the Jetpack_Sync_Module interface.
filter
`jetpack_sync_prevent_sending_comment_data`
Filters whether to prevent sending comment data to .com Passing true to the filter will prevent the comment data from being sent to the WordPress.com. Instead we pass data that will still enable us to do a checksum against the Jetpacks data but will prevent us from displaying the data on in the API as well as other services.
action
`jetpack_full_sync_network_options`
Tells the client to sync all options to the server
action
`jetpack_full_sync_options`
Tells the client to sync all options to the server
action
`jetpack_full_sync_end`
Fires when a full sync ends. This action is serialized and sent to the server.
action
`jetpack_full_sync_start`
Fires when a full sync begins. This action is serialized and sent to the server so that it knows a full sync is coming.
action
`jetpack_full_sync_cancelled`
Fires when a full sync is cancelled.
filter
`jetpack_is_mobile`
Filter the value of jetpack_is_mobile
filter
`pre_jetpack_is_mobile`
Filter the value of jetpack_is_mobile before it is calculated. Passing a truthy value to the filter will short-circuit determining the mobile type, returning the passed value instead.
