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 Instagram Story as a PNG:
curl -X POST https://app.html2img.com/api/v1/templates/instagram-story \
-H "X-API-Key: YOUR_API_KEY" \
-H "Content-Type: application/json" \
-d '{"title":"Behind the scenes","subtitle":"How our team built the v3 release in six weeks.","eyebrow":"NEW EPISODE","cta":"Swipe up","background_image_url":"https://picsum.photos/seed/insta-story/1080/1920","background_color":"#0F0F1A","accent_color":"#FACC15"}'For the full PHP, Node and Python equivalents, plus every input the template accepts, see the Instagram Story API reference. Setting up your key is covered in the authentication guide.
