How to get/enable public URL for media uploaded to slack using slack API

Question

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.

Is there any way we can enable those public_link, so that media can be accessible outside slack.

Answer 1

In general Slack files are not public, but you can open public access to them if you want.

Call the method files.sharedPublicURL after you uploaded it to enable public access to a Slack file via its permalink_public URL.

See API documentation for more info.

Answer 2

To enable the public link, your app requires the file:write:user permission scope from the team, the team's access_token and the specific file_id you're trying to make public

Then send a request to Slack's files.sharedPublicURL(access_token, file_id) endpoint to receive a JSON object containing the file id.

You can use the new Slack Events API to have Slack send your app file information, including the file id, when events as file_created or file_shared occur. Here's a list of events Slack supports
