Overview

Supportivekoala is an API that auto-generates custom images by filling in templates with dynamic text or data, returning a ready-to-use image URL. It is useful for creating social share cards, personalized banners, email headers, and certificate images programmatically. An API key is required and a free tier is available for getting started.

💡

Beginner Tip

First create a template in the Supportivekoala dashboard, note its template ID, then POST your variable values to the API to get back a rendered image URL you can embed anywhere.

Common Errors & Troubleshooting

401 Unauthorized Missing or incorrect API key in the request header
✓ Pass your API key in the x-api-key header; find it in your Supportivekoala account settings
422 Unprocessable Entity Template ID does not exist or required template parameters are missing
✓ Check your template ID in the dashboard and ensure all required variable names in the template are included in the params object
Slow image generation First render of a template can be slower as assets are loaded
✓ Subsequent renders of the same template are faster due to caching; consider pre-warming templates in non-time-sensitive workflows
