# Moving to granular permission scopes
On 22 January 2020, Slack released granular permissions (opens new window), deprecating the old
Previously, bot users were special and required the umbrella
bot scope. Now, new Slack apps can request individual scopes for their bot users.
If you had custom Slack bots before 22 January 2020, there's a chance it has the
bot scope and will require migration to the new scopes by late 2021. You can check whether your custom bot has the
bot scope by heading over to your app management page (note that you either have to be the app creator or collaborator to have access to this page), and looking under OAuth & Permissions.
# Migration timeline
February 21, 2020 Slack will require any NEW apps to use granular permissions. There's no real action on your part - just be aware that if you create any new custom bots, it's normal for them to have different scopes than your old bots.
Late 2021 Existing apps that have not upgraded will be assessed by Slack and conversations involving those apps will be delisted by them. We strongly recommend that you migrate your custom bot way before this time.
# What happens if I don't update my custom bot's scopes?
By late 2021, conversations involving your custom bot may be delisted by Slack upon their assessment. It's highly recommended to do it way before that - especially since migration is easy.
# Will any of my bot functionality be affected before/after migration?
However, the RTM API (opens new window) is not accessible to the new bot tokens (and hence aren't usable after migration). If your app requires RTM functionality, Slack has advised not to perform this migration for your app.
# Migrating to the new scopes
On your app management page on Slack, head over to Update to Granular Scopes. Navigate to granular permission scopes
In Step 1, do not select any bot token scopes.
In Step 2, select the following user token scopes:
User token scopes
In Step 3, verify your scope selections, then click on Yes, migrate my app. When further prompted by Slack to ensure that your app does not require RTM APIs, click on Yes I'm sure.
Verify scope selections
In Step 4, you do not have to change your OAuth code as it is handled by Workato. Click on I've updated my app.
Click on I've updated my app
Finally, reinstall your app for the new permission scopes to take effect. Reinstall your app
