I usually use orjson. Not only because of its tremendous performance, but also for its great (RFC-3339 compliant) support of datetime:

import orjson # via pip3 install orjson
from datetime import datetime

data = {"created_at": datetime(2022, 3, 1)}

orjson.dumps(data) # returns b'{"created_at":"2022-03-01T00:00:00"}'

If you would like to use datetime.datetime objects without a tzinfo as UTC you can add the related option:

orjson.dumps(data, option=orjson.OPT_NAIVE_UTC) # returns b'{"created_at":"2022-03-01T00:00:00+00:00"}'
