Keeping track of what’s changing — across infrastructure, policies, security, and product — is hard.
Updates are scattered across tools, buried in chats, or lost in release notes.

The ChangeCrab API helps you bring all of that together.
It turns updates from anywhere in your stack into structured, searchable, linkable entries that everyone can understand.

Here are six practical ways to use it in your workflow.

1️⃣ Infrastructure Change Log

Who it helps: DevOps, SRE, and Platform teams
Goal: Track every infrastructure change automatically.

When servers scale, containers deploy, or databases migrate, those are changes worth recording.
ChangeCrab makes this automatic by integrating with the tools you already use.

What to Connect

• Terraform / CloudFormation: Resource updates
• Kubernetes: Pod deployments, config changes
• Database tools: Schema and index migrations
• Monitoring: Incidents, alerts, and resolutions

Why It’s Useful

• Faster incident response with a clear timeline
• Automatic documentation for audits
• Consistent visibility across DevOps and Engineering
• No more manual change tracking

API in Action

• POST /changelogs → Create an “Infrastructure” changelog
• POST /changelogs/{id}/posts → Log resource changes
• Use statuses: planned → in_progress → completed
• Link to Terraform states, dashboards, or runbooks
• Send real-time alerts to Slack or Discord

2️⃣ Business Process & Policy Tracker

Who it helps: HR, Operations, and Leadership
Goal: Keep teams aligned on organisational updates.

When policies or processes change, communication often gets lost between tools or emails.
ChangeCrab keeps everything in one clear, accessible log.

What to Track

• Policy and benefits updates
• SaaS tool adoptions or retirements
• Team and role changes
• Compliance notes and audit results

Why It’s Useful

• Reduces confusion around new policies
• Simplifies onboarding and accountability
• Maintains an internal record of business evolution
• Makes cross-departmental changes easier to follow

API in Action

• Multiple changelogs per department (e.g. HR, Ops)
• POST /changelogs/{id}/posts → Record updates
• Use draft mode for reviews
• Set release dates for when policies go live
• Keep internal-only logs private

3️⃣ Security & Compliance Log

Who it helps: Security, IT, and Compliance teams
Goal: Build a single, reliable audit trail.

Security events happen constantly — new vulnerabilities, certificate renewals, or permission changes.
ChangeCrab can record and categorise all of it, automatically.

What to Track

• Vulnerability discoveries and patches
• Access control and MFA changes
• Security incidents and their resolutions
• SSL renewals and domain updates

Why It’s Useful

• Easy compliance reporting (SOC2, ISO27001, GDPR)
• Faster incident analysis with historical context
• Fewer spreadsheets, fewer missed details
• Consistent audit-ready documentation

API in Action

• POST /changelogs → Private security log
• POST /changelogs/{id}/posts → Add entries
• Categories: Vulnerability, Access Control, Incident, Certificate
• Status tracking: investigating → patched → verified
• Link to CVEs, tickets, or SIEM dashboards
• Use webhooks for critical alerts

4️⃣ API & Schema Tracker

Who it helps: Backend engineers, API teams, SDK maintainers
Goal: Keep developers and partners updated about changes.

APIs evolve — and communicating those changes is key to avoiding confusion.
ChangeCrab tracks every change automatically so developers and users can stay in sync.

What to Track

• Swagger/OpenAPI or GraphQL schema changes
• Deprecations, additions, and version releases
• SDK or documentation updates
• Database migrations that affect endpoints

Why It’s Useful

• Prevents support tickets for breaking changes
• Keeps internal and external developers informed
• Builds trust through transparent version tracking
• Saves hours of manual changelog writing

API in Action

• POST /changelogs/{id}/posts → Record schema updates
• Categories: Breaking Change, New Endpoint, Deprecated, SDK Update
• Lifecycle statuses: planned → in_progress → completed
• Public changelogs for external consumers
• Auto-import from API documentation RSS feeds

5️⃣ Universal Event Aggregator

Who it helps: Cross-functional teams
Goal: Create one unified view of everything that happens.

If your team uses tools like GitHub, Jira, Linear, or Slack, information gets fragmented.
The ChangeCrab API can pull all these events together into one consistent feed.

What to Connect

• GitHub / GitLab: Commits, pull requests, releases
• Jira / Linear: Issue updates and ticket resolutions
• Slack / Discord: Key announcements
• RSS: Docs, blogs, and status pages

Why It’s Useful

• One centralised view of company activity
• Easy weekly summaries for reports or newsletters
• Reduced noise and duplication
• Better visibility across engineering, product, and ops

API in Action

• GET /changelogs → List all changelogs
• POST /changelogs/import/rss → Add feeds
• POST /changelogs/{id}/posts → Log events
• PUT /changelogs/{id}/posts/{postId} → Update as events evolve
• Use the Stats API for engagement summaries

6️⃣ Automated Product Newsletter

Who it helps: Product, Marketing, and Customer Success
Goal: Turn changelog entries into customer-ready newsletters.

If you’re already logging your product changes, you can automatically turn them into beautiful, engaging email updates.

How It Works

1. A weekly or monthly job calls GET /changelogs/{id}/posts
2. Filters posts by date and category
3. Groups them into sections (New, Improved, Fixed)
4. Builds an HTML email
5. Sends through Mailchimp, SendGrid, or AWS SES

Why It’s Useful

• Keeps customers informed without manual effort
• Consistent, branded updates every week or month
• Tracks engagement through open and click rates
• Works directly from the same changelog data

Example

API in Action

• GET /changelogs/{id}/posts → Fetch updates
• Use the Stats API to feature top-viewed items
• Include links back to full entries

Common Patterns to Reuse

• Separate logs: Infrastructure, security, business, product
• Statuses: planned → in_progress → completed
• Categories: Custom per changelog for filtering
• Automation: Favour hooks and imports over manual entry
• Notifications: Push updates to Slack or email
• Linking: Connect everything back to source systems
