send email API

Sure — if you want to send an email via an API, here’s a simple example using Node.js + Nodemailer for SMTP, or SendGrid/Mailgun if you want a hosted email API.

Example: Send email with a REST API using Node.js

1) Install

npm install express nodemailer

2) Create API endpoint

const express = require('express');
const nodemailer = require('nodemailer');

const app = express();
app.use(express.json());

app.post('/send-email', async (req, res) => {
  const { to, subject, text } = req.body;

  try {
    const transporter = nodemailer.createTransport({
      host: 'smtp.gmail.com',
      port: 587,
      secure: false,
      auth: {
        user: process.env.EMAIL_USER,
        pass: process.env.EMAIL_PASS,
      },
    });

    const info = await transporter.sendMail({
      from: process.env.EMAIL_USER,
      to,
      subject,
      text,
    });

    res.json({ success: true, messageId: info.messageId });
  } catch (error) {
    res.status(500).json({ success: false, error: error.message });
  }
});

app.listen(3000, () => console.log('API running on port 3000'));

3) Call the API

curl -X POST http://localhost:3000/send-email \
  -H "Content-Type: application/json" \
  -d '{
    "to": "recipient@example.com",
    "subject": "Hello",
    "text": "This is a test email"
  }'

If you meant “send email API” in another stack:

• Python: Flask + smtplib / SendGrid SDK
• PHP: Laravel Mail / PHPMailer
• Java: Spring Boot + JavaMailSender
• C#: ASP.NET + MailKit
• JavaScript frontend: call your backend API only; don’t send SMTP creds from browser

If you want, I can give you:

1. a complete email-sending API in your preferred language, or
2. an integration with SendGrid, Mailgun, AWS SES, or Gmail.
