Getting app whitelisted


We want to use the endpoint that allow to update allow_dms_from.

Currently we are getting Twitter API returned a 403 (Forbidden), Client is not permitted to perform this action. Searching in this forum I ended up with this link: API Updates for Direct Messages Rules which points that only whitelist apps are allowed to use that endpoint.

But in the current form on this link I don’t see anything regarding to whitelist. How can I initiate the process of my app getting whitelisted?

Best Regards.
