      Slack Connector Configuration Guide

      The Slack Connector in Rayven.io integrates Slack messaging into your workflows, enabling real-time notifications, automated message posting, and message retrieval.

      What It Does

      • Sends automated messages to Slack channels or DMs.

      • Retrieves messages, threads, and channel history.

      • Monitors channels for new posts and triggers workflows.

      • Supports both public and private channels.

      How to Use

      Rayven Workflow Implementation

      1. Create a Slack App

        • Go to Slack API Apps and create a new app.

        • Add scopes based on your use case (e.g., chat:write, conversations:read, groups:history).

        • Install the app to your workspace and copy the OAuth token.

      2. Add Slack Credentials in Rayven

        • Go to Settings → Credentials in Rayven.io.

        • Add your Slack OAuth token and save.

      3. Add a Slack Node to Your Workflow

        • From Input Nodes (retrieving data) or Output Nodes (sending data), select a Slack operation.

      4. Configure the Node

        • Provide required parameters such as Channel ID, Message Text, or Timestamp.

      5. Test & Activate

        • Test the connection to ensure it works as expected, then activate your workflow.

      Preconfigured Slack Endpoints

      Endpoint Name Description Type API Documentation
      Send a Message Post a message to a channel. Output chat.postMessage
      Retrieve Message Thread Get all messages in a thread. Input conversations.replies
      Monitor Private Channel Messages Detect new posts in a private channel. Input groups.history
      Monitor Public Channel Messages Detect new posts in a public channel. Input conversations.history
       

      Note: You will need valid Slack OAuth tokens with the correct scopes for these endpoints.

      Adding Custom Endpoints

      If your needed operation is missing:

      1. Use the HTTP Request Node

        • Select Slack as the credential type.

        • Provide:

          • API endpoint URL (see Slack Web API Docs)

          • HTTP method (GET, POST, etc.)

          • Headers and payload as required.

      2. Request a New Endpoint from Rayven Support

        • Share the Slack API method name and required parameters.

        • Most requests are added within 72 hours.

      Authentication

      Method Notes
      OAuth2 (Bot Token) Recommended; provides secure, scoped access.
      User Token For actions requiring a user’s permissions.
       

      See Slack Authentication Guide for details.

       Best Practices

      • Use scoped OAuth tokens to limit access.

      • Store credentials securely in Rayven’s Credential Manager.

      • Test with a dedicated Slack test channel before production.

      • Avoid excessive API calls to prevent rate limiting (Rate Limits Docs).

      Use Cases

      • Send workflow alerts to operations channels.

      • Retrieve message threads for audit and tracking.

      • Monitor private or public channels for trigger events.

      • Integrate incident management workflows with Slack notifications.
