Quick Start

Get up and running in minutes with Sendook

1

Sign up and get your API key

Create an account at sendook.com and generate your API key from the dashboard.
Your API key is used to authenticate all requests to the Sendook API. Keep it secure and never share it publicly.
2

Install the SDK or use the REST API

Choose your preferred integration method:
npm install @sendook/node
Or use the REST API directly with any HTTP client.
3

Create your first inbox and send an email

Start sending and receiving emails programmatically:
import Sendook from "@sendook/node";

const client = new Sendook("your_api_key");

// Create an inbox
const inbox = await client.inbox.create({
  name: "support",
  email: "[email protected]"
});

// Send an email
await client.inbox.message.send({
  inboxId: inbox.id,
  to: ["[email protected]"],
  subject: "Welcome to Sendook!",
  text: "Thanks for signing up.",
  html: "<p>Thanks for signing up.</p>"
});

Set up webhooks to receive emails

Configure webhooks to handle incoming emails automatically:
await client.webhook.create({
  url: "https://your-app.com/webhooks/email",
  events: ["message.received"]
});
Your webhook will receive parsed email data whenever a message arrives in your inbox.
