Quick Start

Get up and running with Sendvaults in minutes. You'll need an API key from your dashboard.

1. Install via HTTP (REST API)

No SDK required. Send emails directly via our REST API:

curl -X POST https://api.sendvaults.com/v1/emails \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"from":"hello@yourdomain.com","to":"user@example.com","subject":"Hello!","html":"<p>Welcome!</p>"}'

2. Using Node.js

const response = await fetch('https://api.sendvaults.com/v1/emails', {
  method: 'POST',
  headers: {
    'Authorization': `Bearer ${process.env.SENDVAULTS_API_KEY}`,
    'Content-Type': 'application/json'
  },
  body: JSON.stringify({
    from: 'hello@yourdomain.com',
    to: 'user@example.com',
    subject: 'Welcome to our app!',
    html: '<h1>Welcome!</h1><p>Thanks for signing up.</p>'
  })
});

Tip: Always store your API key as an environment variable. Never hardcode secrets in your source code.

Authentication

All API requests require authentication using a Bearer token. Generate and manage API keys from your Sendvaults dashboard.

API Key Header

Authorization: Bearer sv_live_xxxxxxxxxxxxxxxxxxxx

Keep your API keys secure. Do not commit them to source control. Use environment variables or a secrets manager.

Domain Setup

To send emails from your own domain, you'll need to verify ownership and configure DNS authentication records.

Required DNS Records

SPF — Authorizes Sendvaults servers to send on behalf of your domain.
DKIM — Adds a cryptographic signature to verify email authenticity.
DMARC — Defines how receivers handle failed authentication.

Once your domain is verified, emails sent through Sendvaults will appear to come from your brand, improving deliverability and trust.
