To do so, follow two steps:

git clone [email protected]:margaritageleta/slack-export-history.git

Go to https://api.slack.com/apps and go straight to Create New App. Choose your Workspace and press Create App. Then, click on your app and go to Add features and functionality -> Permissions -> Scopes and add the following scopes in User Token Scopes (be careful, User Token Scopes NOT Bot Token Scopes):

• channels:history
• channels:read
• groups:history
• groups:read
• im:history
• im:read
• mpim:history
• mpim:read
• users:read

Then install the app in your workspace (you can go to OAuth & Permissions section and press Reinstall app), accept the permissions and copy the OAuth Access Token.

sudo pip3 install requests

sudo pip3 install pick

Go ahead to the terminal and run python3 slack.py --token COPY_YOUR_OAUTH_TOKEN_HERE. Choose the DM conversation you want to export and we are done!
