Edge Functions

Supabase Edge Functions let you run server-side code securely. Cadrant uses them to integrate external APIs, process payments, send emails and any logic that shouldn't be exposed client-side.

Common use cases

• Payment integrations (Stripe, PayPal, etc.).
• Transactional emails (Resend, SendGrid, etc.).
• AI API calls (OpenAI, Anthropic, etc.).
• Webhooks and notifications to third-party services (Slack, CRM, etc.).
• Any logic requiring secret API keys.

How it works

1. Describe the desired integration in your prompt (e.g.: 'Add Stripe payment for subscriptions').
2. Cadrant generates the Edge Function code and deploys it to your Supabase project.
3. Sensitive API keys are stored in environment variables, never in frontend code.
4. The frontend application calls the Edge Function securely via the Supabase API.

Security

• Edge Functions run in an isolated environment on Supabase servers.
• API keys and secrets are never exposed to the user's browser.
• Add your environment variables in the Database > Environment panel of your project.
• Functions can verify user authentication before executing business logic.
