Slack - Workspace Operations

Overview

Navigate Slack workspaces, access channels, download images, and export list data. Includes authentication handling.

URLs

Critical Constraints

• Authentication Required: Must be logged in - redirects to workspace-signin if session expired
• Direct URLs Preferred: Use direct workspace/channel URLs when authenticated
• reCAPTCHA: Email login may trigger reCAPTCHA requiring manual intervention
• Channel ID Format: Public channels start with C, DMs start with D

Workflow: Login via Email Magic Code

When accessing workspace URL without active session, Slack redirects to workspace-signin.

1. Enter Workspace URL

At workspace-signin page:

1. Find input field labeled "Enter your workspace's Slack URL"
2. Enter workspace slug (e.g., example for example.slack.com)
3. Click "Continue" button

2. Select Authentication Method

At workspace login page:

• Google: OAuth with Google account
• Apple: OAuth with Apple ID
• Email: Magic code sent to email (detailed below)
• Password: Traditional password login (via "sign in with a password instead" link)

3. Email Magic Code Flow

1. Enter email address in input field
2. Complete reCAPTCHA if prompted (requires manual interaction)
3. Click "Sign In With Email" button
4. Check email for 6-digit code
5. Enter code in 6 digit input fields (digit 1-6)

4. Verify Login Success

After successful authentication:

• URL changes to https://app.slack.com/client/\{WORKSPACE_ID\}/\{CHANNEL_ID\}
• Channel sidebar visible on left
• Message area displayed in center

Workflow: Access Workspace

1. Navigate to Workspace URL

Use direct URL: https://app.slack.com/client/\{WORKSPACE_ID\}

If authenticated, bypasses login and opens directly into workspace.

2. Handle Redirect to Login

If redirected to workspace-signin, follow "Login via Email Magic Code" workflow above.

3. Verify Workspace Loaded

Check for:

• Channel sidebar visible
• Message area displayed
• Workspace name in header
