Heroku review app creation with Github Actions

review_app_creation.rb

# Github Actions should look something like:

# name: CI
# on: [pull_request]
# jobs:
#   build_review_app:
#     name: Review app builder
#     runs-on: ubuntu-latest
#     steps:
#       - name: Checkout code
#         uses: actions/checkout@v2
#       - name: Setup Ruby
#         uses: ruby/setup-ruby@v1
#         with:
#           bundler-cache: true
#       - name: Build Review App
#         env:
#           GH_TOKEN: ${{ secrets.GH_TOKEN }}
#           HEROKU_TOKEN: ${{ secrets.HEROKU_TOKEN }}
#           PIPELINE_ID: ${{ secrets.PIPELINE_ID }}
#         run: |
#           bundle exec rake heroku:app_build


# Add this line to your application's Gemfile:
# gem 'platform-api', '~> 3.0.0'

# Now we create the following task:
namespace :heroku do
  desc 'Create and update review heroku app'
  task :app_build do
    heroku_token = ENV.fetch('HEROKU_TOKEN')
    github_token = ENV.fetch('GH_TOKEN')

    github_repository = ENV.fetch('GITHUB_REPOSITORY')
    github_sha = ENV.fetch('GITHUB_SHA')
    branch = ENV.fetch('GITHUB_HEAD_REF')
    pr_number = ENV.fetch('GITHUB_REF').remove('refs/pull/').remove('/merge').to_i
    client = PlatformAPI.connect_oauth(heroku_token)
    review_app = PlatformAPI::ReviewApp.new(client)
    build = PlatformAPI::Build.new(client)

    url = "https://user:#{github_token}@api.github.com/repos/#{github_repository}/tarball/#{branch}"

    # first we check if there is already a release for that app
    created_review_app = review_app.list(pipleine_id).find { |app| app['pr_number'] == pr_number }

    if created_review_app.blank?
      puts "Creating app on Heroku and deploying branch #{branch} with PR #{pr_number}..."

          pipeline: pipleine_id,
          source_blob: {
            url: url,
            version: github_sha
          }
        }
      )
    else
      puts "Updating review app on Heroku for branch #{branch} with PR #{pr_number}..."
      puts build.create(

        {
