GitHub Actions: Link GitHub Pull Request to Backlog issue.

• Backlog Premium plan (ref. Backlog Pricing)
• Create custom field named "Pull Request" in Backlog issue

# .github/workflows/backlog-pr-link.yml
name: 'Link PR to Backlog'

on:
  pull_request:
    types: [opened, edited]

jobs:
  backlog-pr-link:
    runs-on: ubuntu-latest
    steps:
      - uses: toshimaru/[email protected]
        with:
          backlog-api-key: "${{ secrets.BACKLOG_API_KEY }}"
          backlog-host: "your-org.backlog.com"

If the pull request doesn't contain a Backlog URL, no need to run this action.

To avoid this situation, you can skip the job by using if expression as follows:

# Run the job only when the pull request contains a Backlog URL
jobs:
  backlog-pr-link:
    runs-on: ubuntu-latest
    if: contains(github.event.pull_request.body, 'https://yourhost.backlog.com/')
    steps:
      - ...
