How RocketHooks Works with Slack

RocketHooks monitors Slack’s API endpoints to detect changes in your workspace: new messages in specific channels, user presence updates, channel membership changes, and more. By polling Slack’s API at configurable intervals, RocketHooks transforms Slack data into real-time webhook events that feed into your automation pipelines.

Works with any Slack workspace with bot token access.

Authentication Setup

Create a Slack app and install it to your workspace. Use the bot token for API monitoring:

{
  "auth": {
    "type": "bearer",
    "token": "xoxb-YOUR-SLACK-BOT-TOKEN"
  }
}

Required scopes for monitoring: channels:history, channels:read, users:read, team:read.

Endpoint Examples

Monitor Channel Messages

Track new messages in a specific channel:

{
  "url": "https://slack.com/api/conversations.history?channel=C0123456789&limit=10",
  "method": "GET",
  "pollInterval": 30,
  "changeDetection": {
    "strategy": "jsonpath",
    "expression": "$.messages[*].ts"
  }
}

Monitor User Presence

Detect when team members update their status or go offline:

{
  "url": "https://slack.com/api/users.list?limit=100",
  "method": "GET",
  "pollInterval": 300,
  "changeDetection": {
    "strategy": "jsonpath",
    "expression": "$.members[*].profile.status_text"
  }
}

Monitor Channel Membership

Watch for changes to channel membership:

{
  "url": "https://slack.com/api/conversations.members?channel=C0123456789&limit=200",
  "method": "GET",
  "pollInterval": 600,
  "changeDetection": {
    "strategy": "deep-compare"
  }
}

Common Patterns

Team Coordination Triggers

Monitor Slack channels for new messages and route change events via webhooks to your backend systems. Useful for triggering automated workflows when specific channels receive updates.

User Activity Tracking

Track user presence and status changes across your workspace. When team members update their status or go inactive, send webhook events to your HR or project management tools for activity reporting.

Channel Audit and Compliance

Monitor channel membership changes and message activity for compliance purposes. Route change events to your audit logging system via webhooks.

Delivery Channels

Webhooks: Route Slack API change events to any HTTP endpoint with HMAC-signed payloads and automatic retries

Additional delivery channels (Slack notifications, email, SMS) coming soon.
