DevOps & Automation

Developer Automation

Trigger CI/CD pipelines, refresh datasets, and automate internal workflows the moment any external web content changes.

The challenge

The data you need is public.
The alerts aren't.

Development workflows often depend on external data sources — API docs, partner changelogs, dataset pages — but there's no event-driven way to react when those sources change.

No notification when a partner API adds or deprecates endpoints
Dataset-refreshing pipelines run on fixed schedules, not on actual updates
Manual checks for dependency security advisories and CVEs
DiffHook solves this in minutes

How it works

Three steps to production

01

Connect the external source

Partner API docs, upstream changelogs, CVE databases, dataset portals — anything with a public URL.

02

DiffHook polls the source

When the changelog updates, when a new CVE is published, when a dataset version changes — an event fires.

03

Trigger your pipeline

Call the GitHub Actions dispatch API, post to a build webhook, update a database record, or run any downstream automation.

Use cases

What teams build with this

API changelog monitoring

Webhook → GitHub Actions

Get a webhook when a partner's API changelog updates. Trigger a review task before you discover breaking changes in production.

Dataset refresh triggers

Webhook → Airflow DAG

Monitor public dataset portals and trigger your ETL pipeline only when new data is actually available — not on a fixed cron.

Security advisory alerts

Webhook → Jira ticket

Watch NVD, NIST, and vendor security pages for CVEs affecting your stack. Trigger immediate dependency audits.

Dependency release tracking

n8n → PR draft

Monitor npm, PyPI, or GitHub releases pages for key dependencies and get notified when a new version drops.
