Date time Filter

I am using the Advanced Custom Fields plugin on wp rest api v2.

I can not filter by custom field when taking data in Json format.

I want to filter according to the date part in the special field in acf, but it posts to me according to the published date.

I want to filter by acf.game_date

Sample json

{"id":12,
"date":"2017-02-24T01:00:33",
"date_gmt":"2017-02-23T23:00:33",
type":"post",
"acf":{"game_date":"20170101"},}
