GitHub Action

Test webhooks in your CI pipeline with the reqdump GitHub Action:

steps:
  - uses: bakasa/reqdump-action@v1
    id: webhook
  - run: |
      curl -X POST ${{ steps.webhook.outputs.endpoint }}/test \
        -H 'Content-Type: application/json' \
        -d '{"event":"payment.succeeded"}'
  - run: |
      curl ${{ steps.webhook.outputs.url }}/api/summary

No external service, no accounts — runs entirely on the GitHub Actions runner. Captures and asserts on webhook payloads during integration tests.
