Before you start, first you have to get a User OAuth Token from Slack so that you can make authorized API calls to Slack from Salesforce.
Step 1: Create a Slack App
- Go to Slack API: Navigate to https://api.slack.com/apps.
- Create a New App: Click on “Create New App”.
- From scratch: Choose this option.
- App Name: Give your app a name.
- Workspace: Select the Slack workspace you want to use.
- Click “Create App”.
Step 2: Configure the App
- OAuth & Permissions:
- Navigate to “OAuth & Permissions” in the left sidebar.
- Scopes: Scroll down to “Scopes” and add the necessary scopes under “User Token Scopes”. For archiving/unarchiving a channel, you need:
- channels:write, groups:write
Step 3: Install App to Workspace:
- Scroll up to “OAuth Tokens for your workspace”.
- Click “Install App to Workspace”.
- Follow the prompts to authorize the app for your workspace.
- After installation, you will receive a User OAuth access token.
- Copy the token and store it in a safe place within Salesforce such as named credentials, or Custom Settings, etc. So that you can use it in the apex class.
Apex Class for Archiving Slack Channel: This class uses a hard-coded access token which is a User OAuth Token from Slack.
