Body

Hi everyone 👋

I’ve been exploring GitHub integrations using APIs and webhooks, and I’m curious how people are actually using them in production systems.

For those who’ve built with GitHub’s APIs (REST or GraphQL) or webhooks:

What kind of application or integration did you build? (automation tools, dashboards, CI/CD extensions, bots, etc.)
Did you prefer the REST API or the GraphQL API, and why?
How are you handling webhook events reliably (retries, failures, scaling)?
Any challenges with rate limits, authentication, or data consistency?
What are some underrated use cases or ideas people don’t usually think about?

Also, if you’ve built GitHub Apps or OAuth Apps, I’d love to hear about your experience designing and scaling them.

Looking forward to learning from real-world implementations 🚀

💬 Sample Answer (you can post this yourself to kickstart the discussion)

I recently built a small integration that listens to GitHub webhook events and automates parts of a hiring workflow.

🏗️ Use Case
When a candidate submits a project (via repo link), we:
Fetch repo data using GitHub REST API
Analyze commits, tech stack, and activity
Trigger further processing in our system
⚙️ REST vs GraphQL

I started with the REST API (simpler and well-documented), but later explored GraphQL for:

Fetching nested data in a single request
Reducing multiple API calls

Still, REST felt easier for quick integrations.

🔔 Webhooks Setup
Subscribed to events like push, pull_request
Used a backend service to:
Validate webhook signatures
Queue events (important for reliability)
Process asynchronously
🚧 Challenges
Handling duplicate webhook deliveries
Managing rate limits during heavy usage
Ensuring idempotency in event processing
💡 Key Takeaway

Webhooks are powerful, but you must design for:

retries
failure handling
event duplication

Otherwise things break silently.

If anyone has built large-scale GitHub Apps or used GraphQL extensively, I’d love to know how you structured your system 👀

I’ve been working on a GitHub integration that combines APIs + webhooks to automate parts of a developer workflow (somewhat similar to CI extensions + analytics).
