Conversations API and new scopes available for workspace apps
Workspace apps can now use a simplified interface for working with the Conversations API methods. A workspace app can request three new scopes:
conversations:write. These three scopes cast an umbrella of permission over each different conversation type: channels, DMs, or anything in between.
This feature was exclusive to our workspace apps developer preview. The preview has now ended, but fan-favorite features such as token rotation and the Conversations API will become available to classic Slack apps over the coming months.
These new scopes make it even easier to use Conversations API methods, allowing apps to negotiate permissions for, and then interact with, all types of conversations at once.
Workspace apps can now make full use of our Conversations API methods, using a simplified scope model that covers all conversation types. To use the Conversations API, your workspace app can request three scopes:
The workspace permission model revolves around the specific resources awarded to your app. By using our new scopes with the Conversations API, your app can ignore the many scopes pinned to specific conversation types. This way, your app can use a normalized interface for all types of conversations: public, private, or otherwise.
We already made similar logical changes to our API by introducing the Conversations API methods. With the
conversations.list method, for example, we return all conversations that the requester should be able to see, regardless of whether they're private channels, public channels, or direct messages.
Now, if a workspace app calls
conversations.list, it'll find all the conversations the app is entitled to participate in, right in one place.
These new shiny scopes cover all that workspace apps need to converse, so we're deprecating use of the older scopes by workspace apps:
You'll have plenty of time to migrate your app to the new
conversations scopes before the old ones are retired.
To rid your app of deprecated scopes, just head to the OAuth & Permissions panel of your Slack app management console and click the trash button next to the scopes you no longer need:
Conversations API methods like
conversations.list will continue to accept the old type-specific scopes, even from workspace apps, for now. However, we strongly encourage workspace apps to upgrade to the umbrella
conversations: scopes. They're just better.
Visit the OAuth & Permissions panel of your Slack app management console to request the new scopes and stop requesting the old ones.
Be sure to reinstall your app to take advantage of the new scopes!
If you're installing your app on multiple workspaces, chances are high that you've entered into the brave new-ish world of OAuth. In that case, you'll want to change the URI you redirect your users to by passing the new
conversations scopes among the GET parameters.
Finally, if you're requesting any of these deprecated scopes via the Permissions API for the purpose of progressively gaining permissions: hooray! Gold star for you. You can request the new scopes directly in calls to
We launched these changes today, June 22, 2018. Please let us know how we can make your Workspace Apps easier to build and simpler to maintain.Review other recent updates
