<UseCaseHero title="Auto-Fix Failing CI Builds" description="Add a GitHub Action that calls Devin to fix failing CI on your PRs." prompt="Help me set up a GitHub Action that automatically triggers Devin to fix failing CI builds. Follow the guide at https://docs.devin.ai/use-cases/gallery/api-github-actions-ci-fix and walk me through each step: storing the API key, adding the workflow file, and scoping it to the right failures." category="Automations" features="API" />

<div className="uc-detail-wrapper">
  <Tip>Don't want to set this up manually? Paste a link to this page into a Devin session and ask it to set everything up for you.</Tip>

  <Steps>
    <Step title="Store your Devin API key in GitHub">
      The workflow calls Devin's [v3 API](/api-reference/v3/overview) to create sessions programmatically. Create a service user and store its token as a GitHub Actions secret:

      1. Go to [app.devin.ai](https://app.devin.ai/?utm_source=docs\&utm_medium=use-case-gallery) > **Settings** > **Service Users** and create a service user with `ManageOrgSessions` permission
      2. Copy the API token shown after creation — it's only displayed once
      3. In your GitHub repo, navigate to **Settings > Secrets and variables > Actions**
      4. Add two secrets: `DEVIN_API_KEY` (the token) and `DEVIN_ORG_ID` (your organization ID — get it by calling `GET https://api.devin.ai/v3/enterprise/organizations` with your token)

      Make sure the repository is already [set up on Devin's Machine](/onboard-devin/environment) so Devin can clone, build, and push to it.
    </Step>

    <Step title="Add the workflow file">
      Create `.github/workflows/devin-ci-fix.yml`. This workflow fires whenever your existing CI workflow completes with a failure, extracts the failing job names, and calls the [Devin API](/api-reference/v3/sessions/post-organizations-sessions) to start a fix session:

      ```yaml theme={null}
      name: Auto-fix CI with Devin

      on:
        workflow_run:
          workflows: ["CI"]
          types: [completed]

      jobs:
        trigger-devin-fix:
          if: >
            github.event.workflow_run.conclusion == 'failure' &&
            github.event.workflow_run.pull_requests[0]
          runs-on: ubuntu-latest
          steps:
            - name: Get failure details
              id: failure
              uses: actions/github-script@v7
              with:
                script: |
                  const run = context.payload.workflow_run;
                  const pr = run.pull_requests[0];
                  const jobs = await github.rest.actions.listJobsForWorkflowRun({
                    owner: context.repo.owner,
                    repo: context.repo.repo,
                    run_id: run.id
                  });
                  const failed = jobs.data.jobs
                    .filter(j => j.conclusion === 'failure')
                    .map(j => j.name);
                  core.setOutput('pr_number', pr.number);
                  core.setOutput('branch', pr.head.ref);
                  core.setOutput('failed_jobs', failed.join(', '));
                  core.setOutput('run_url', run.html_url);

            - name: Trigger Devin session
              run: |
                curl -s -X POST "https://api.devin.ai/v3/organizations/${{ secrets.DEVIN_ORG_ID }}/sessions" \
                  -H "Authorization: Bearer ${{ secrets.DEVIN_API_KEY }}" \
                  -H "Content-Type: application/json" \
                  -d "{
                    \"prompt\": \"CI failed on PR #${{ steps.failure.outputs.pr_number }} in ${{ github.repository }}. Failed jobs: ${{ steps.failure.outputs.failed_jobs }}. Run: ${{ steps.failure.outputs.run_url }}. Branch: ${{ steps.failure.outputs.branch }}. Read the CI logs, identify the root cause, and push a fix to the branch.\"
                  }"
      ```

      Replace `"CI"` in the `workflows` array with the exact `name:` from your existing CI workflow file (e.g., `"Tests"`, `"Build & Test"`).

      Use the `tags` field in the request body (e.g., `"tags": ["ci-fix", "pr-312"]`) to track which CI failures have already triggered sessions and avoid duplicates.
    </Step>

    <Step title="What happens when CI fails">
      When a PR's CI run fails, the Action extracts failure details and passes them to Devin as a session prompt. Here's a typical auto-fix flow:

      1. **Reads the CI logs** — Devin opens the run URL and parses the error output, stack traces, and test results from the failing jobs
      2. **Traces the error to code** — Locates the relevant file and line on the PR branch (e.g., `UserList.tsx:34`) and reads the surrounding code and recent diff
      3. **Pushes a fix** — Commits a targeted change directly to the PR branch, which re-triggers CI automatically
      4. **Comments on the PR** — Posts a summary explaining the root cause and what was changed

      Example PR comment from Devin:

      ```
      CI failure in test-unit — fixed

      Root cause: `UserList.tsx:34` calls `.map()` on `props.users`, which is
      undefined when the API returns an empty response body instead of `[]`.

      Fix: Added a fallback — `const users = props.users ?? [];`
      Added a test case for the empty-response scenario.
      All 312 tests passing.
      ```

      <PromptBlock>
        ```txt Follow up on a flaky test theme={null}
        The CI failure was actually a flaky test — it passes on retry. Investigate
        the test at src/__tests__/UserList.test.tsx and fix the flakiness. Check
        if it's a timing issue, race condition, or missing cleanup between runs.
        ```
      </PromptBlock>
    </Step>

    <Step title="Scope it to the right failures">
      Not every CI failure benefits from an auto-fix — infrastructure timeouts and Docker build issues won't be solved by a code change. Add a condition so only relevant job failures trigger Devin:

      ```yaml theme={null}
            - name: Trigger Devin session
              if: >
                contains(steps.failure.outputs.failed_jobs, 'test') ||
                contains(steps.failure.outputs.failed_jobs, 'lint') ||
                contains(steps.failure.outputs.failed_jobs, 'typecheck')
              run: |
                curl -s -X POST "https://api.devin.ai/v3/organizations/${{ secrets.DEVIN_ORG_ID }}/sessions" \
                ...
      ```

      ### Keep fixes reviewable

      Devin pushes a fix commit, but the PR still requires human review before merging. Treat auto-fixes as a head start for the developer, not a replacement for code review. If Devin can't resolve the failure, it comments on the PR explaining what it found so an engineer can pick up from there.
