title: How to get/enable public URL for media uploaded to slack using slack API
body: <p>I'm using slack api to upload media to a public channel, in-response I'm getting different urls for the uploaded media including 'permalink_pulic' which seems as the public URL, but that link doesn't work.Other Links are only accessible by slack team members.</p>
  
  <p>Is there any way we can enable those public_link, so that media can be accessible outside slack.</p>
