Cloudflare Integration

Cloudflare Workers allow you to run serverless code globally. Since standard TCP sockets can be limited in edge environments, routing emails through the Reloop HTTP API is the recommended approach.

Step 1: Bind Secret in Wrangler

To add your Reloop API key to your Cloudflare Worker environment securely, run the following command in your terminal:

wrangler secret put RELOOP_API_KEY

When prompted, input your Reloop API key starting with rl_.

Step 2: Send Email via Fetch in Cloudflare Workers

Send emails with a standard POST request inside your Worker:

export default {
  async fetch(request, env) {
    const response = await fetch('https://api.reloop.dev/v1/emails', {
      method: 'POST',
      headers: {
        'Authorization': `Bearer ${env.RELOOP_API_KEY}`,
        'Content-Type': 'application/json',
      },
      body: JSON.stringify({
        from: 'alerts@yourdomain.com',
        to: 'user@example.com',
        subject: 'Edge Alert',
        html: '<p>Sent from the edge via Reloop!</p>',
      }),
    });

    return response;
  }
};
