I read article on twitter blog - https://blog.twitter.com/2016/speed-up-customer-service-with-quick-replies-welcome-messages-in-direct-messages mentioning about latest release of Welcome message and quick replies.
This article also mentioned that for quick replies APIs features are currently in private beta.
and asked to submit https://dev.twitter.com/build/automation/form this form if you want to use them.
I did that and submitted the form, but not received any notification after that.
Does anyone has any idea how to use those APIs or get access for those APIs?
