Templates

Templates let you create reusable email layouts with dynamic variable substitution. Use {{variableName}} syntax in both the subject and HTML body.

Create a Template

Parameter	Type	Required	Description
name	string	Required	Template name for reference
subject	string	Required	Email subject (supports {{variables}})
html	string	Required	HTML content (supports {{variables}})

Create template

curl -X POST https://fwd.sarthak.online/api/templates \
  -H "Cookie: your-session-cookie" \
  -H "Content-Type: application/json" \
  -d '{
    "name": "Welcome Email",
    "subject": "Welcome, {{name}}!",
    "html": "<h1>Hello {{name}}</h1><p>Welcome to {{company}}.</p>"
  }'

Auto-detected variables

Variables are automatically extracted from your subject and HTML content. Any {{variableName}} patterns are detected and stored with the template.

Variable Substitution

When sending emails with a template, pass a variables object to replace placeholders with actual values.

Send with template variables

// POST /api/send
{
  "to": "user@example.com",
  "templateId": "tmpl_abc123",
  "variables": {
    "name": "Sarah",
    "company": "Acme Inc"
  }
}

The above request with the “Welcome Email” template would produce:

Subject: Welcome, Sarah!
Body: <h1>Hello Sarah</h1><p>Welcome to Acme Inc.</p>
