2. Create a GitHub App

This section deals with setting up a GitHub App which is required for sfops to function. sfops require additional permissions which allow to write into other repository such as 'sfops-dev-central' and also permission to trigger workflows etc. These permissions are beyond what is being provided by the built in GITHUB_TOKEN. A Github App is recommended over using a Service Account and its Personal Access Token, as the service account takes an additional license and has limitations on the api requests.

This guide is crafted to facilitate the user to create a sfops-bot GitHub App to automate the worflows provided out of the box with sfops. It provides a step-by-step approach for creating the app, elaborating on the necessary permissions, installation, and secure storage of sensitive information. You can refer to this link to understand how this work behind the scenes

Workflows	Read & Write	Permit the app to update workflow files, which is vital for maintaining automated processes

Organization Permissions

Permission	Access Level	Purpose

The new GitHub projects are created at organization level, and requires organization permissions

Step 3: Configure Installation Settings

• In the Where can this GitHub App be installed? section:

  • Select "Only on this account" to restrict the app to your organization

  • This ensures the app can only be installed within your organization

Step 4: Create the GitHub App

• Click "Create GitHub App" at the bottom of the form

• You'll be redirected to your new app's settings page

• Keep this tab open - you'll need information from this page in Step 6

Step 5: Install the App

• Navigate to the 'Install App' tab within your app settings

• Click "Install" to initiate the installation process

• Select your organization and choose either:

  • All repositories (recommended for simplicity), or

  • Selected repositories: Include at minimum:

    • sfops

    • sfops-gh-actions

    • sfops-dev-central

    • Your Salesforce project repositories

Step 6: Collect App Credentials and Store as Secrets

Collect the required credentials (from Step 4's settings page):

1. App ID: Note the App ID displayed at the top of your app's settings page

2. Private Key:

   • Scroll down to the Private keys section on your app's settings page

   • Click "Generate a private key"

   • The .pem file will download automatically - save it securely

Store as GitHub secrets:

• Navigate to your sfops repository → Settings → Secrets and variables → Actions

• Create the following:

  • SFOPSBOT_APP_ID: Paste the App ID number from the settings page (store as Repository variable)

  • SFOPSBOT_APP_PRIVATE_KEY: Paste the entire contents of the downloaded .pem file (store as Repository secret)

The workflows provided by sfops utilizes the above variables to authenticated to do repository operations as provided in the below example\

// Sample code demonstrating how the token is used
      - name: Generate a token
        id: generate_token
        uses: actions/create-github-app-token@v1
        with:
          app-id: ${{ var.SFOPSBOT_APP_ID }}
          private-key: ${{ secrets.SFOPSBOT_APP_PRIVATE_KEY }}

      - name: Use the token
        env:
          GITHUB_TOKEN: ${{ steps.generate_token.outputs.token }}
        run: |
          gh workflow <>
