Project Showcase: Changelog Image Generator API
"We shipped X" hero cards for changelogs and launch announcements
Use cases for the Changelog Image Generator API
The Project Showcase template is the shortest path to a working changelog image generator api from your stack. Send a small JSON payload, get back a tested PNG that fits your brand. No browser, no headless Chrome wrangling, no design tooling on your side.
Common reasons people reach for this template:
- Changelog and release announcement images
- Product Hunt launch graphics
- Slack/Discord shipped-it announcements
How it works
2
We render the image
The template is rendered server-side as a 1200x630 PNG (or whatever dimensions the template defines).
3
You get back a URL
The response includes a CDN URL for the PNG. Cache it, embed it, attach it to a tweet, anything you need.
Quick example
A single cURL call to render a Project Showcase as a PNG:
curl -X POST https://app.html2img.com/api/v1/templates/project-showcase \
-H "X-API-Key: YOUR_API_KEY" \
-H "Content-Type: application/json" \
-d '{"version":"v3.2","title":"Live presence and cursor sharing","summary":"See exactly who is editing what, in real time, across every doc in your workspace.","eyebrow":"CHANGELOG","screenshot_url":"https://picsum.photos/seed/project-showcase/900/560","product_name":"Northwind Docs","background_color":"#0B0F1A","accent_color":"#22D3EE"}'For the full PHP, Node and Python equivalents, plus every input the template accepts, see the Project Showcase API reference.
