Introduction

This topic describes how to run the sample applications for the StreamBase® Slack Adapters.

The samples, Slack.sbapp, SlackBot.sbapp and SlackRTMInputAdapter.sbapp, demonstrate how to use Slack Client Adapter to chat and interact with Slack channels. They also demonstrate how to use shared Slack Real Time Messaging Input Adapter to subscribe to certain events and send real-time messages.

Importing This Sample into StreamBase Studio

In StreamBase Studio, import this sample with the following steps:

  • From the top-level menu, select File>Import Samples and Community Content.

  • Enter Slack to narrow the list of options.

  • Select Slack Adapter from the StreamBase Standard Adapters category.

  • Click Import Now.

StreamBase Studio creates a single project for the Slack adapter samples in your current Studio workspace.

Getting Tokens for Your Own Slack App

You must create a Slack application ("Slack app") and obtain a user access token in order to run this sample. Log into https://api.slack.com/apps and perform the following steps (as written, the steps are current as of 10.6.0):

  • Click Create an App, assign a name to your app, and select the workspace where you want to set the app.

  • Add User Token Scopes: channels:write, im:read, mpim:read, groups:read, groups:write, im:write, mpim:write, channels:read.

  • Then click Install App to Workspace from the StreamBase Standard Adapters category.

  • Look for your generated OAuth Access Token.

To get a Bot User OAuth Access Token, go to the Bot Users tab to add a bot to your Slack app.

RTM Control Port

Description

Use the control port to send action commands to the adapter. Tuples enqueued on this port will connect or disconnect the adapter, as well as change the OAuth value at runtime.

Control Port Schema

  • Command, string: the command to send to the adapter.

    The values are:

    • Connect — Starts the Slack Real Time Messaging input adapter.

    • Disconnect — Stops the RTM connection.

  • botUserOAuthToken, string.

    • The OAuth can be changed at runtime
