RunComfy’s API endpoints require Bearer token authentication for secure access. Include your API key in the Authorization header like this: Authorization: Bearer YOUR_API_KEY To get your API key, sign in to RunComfy and go to your profile in the top-right corner, where you will find the API key section. Regenerating the key will immediately invalidate the old one, so update all your integrations without delay. Protect your API key by keeping it out of client-side environments such as browsers, mobile apps, or GUI tools. Instead, route requests through a server-side proxy to keep the key safe and follow best practices for API integrations.
