For developers

Ship in minutes,
not months

Install the SDK, create a document, and send it for signing. The entire flow takes five lines of TypeScript. Webhooks notify you when signers complete their fields.

01
Install the SDK
npm install @korala/sdk
02
Create and send a document
korala.documents.create({ ... })
03
Listen for webhooks
document.completed → your callback
send-nda.ts
typescript
import Korala from "@korala/sdk";

const korala = new Korala({ apiKey: process.env.KORALA_KEY });

// Create a document from a template and send for signing
const document = await korala.documents.create({
  templateId: "tmpl_nda_2024",
  data: {
    clientName: "Acme Corp",
    effectiveDate: "2024-03-15",
  },
  signers: [
    { name: "Jane Smith", email: "jane@acme.com", role: "client" },
    { name: "John Doe", email: "john@company.com", role: "sender" },
  ],
});

// Document is sent — signers receive email notifications
console.log(document.id);   // "doc_a1b2c3d4"
console.log(document.status); // "pending"
