create-envelope.ts
import { Mohor } from '@mohor/sdk';

// Initialize with zero-egress architecture
const client = new Mohor(process.env.MOHOR_API_KEY);

const envelope = await client.envelopes.create({
  templateId: 'tpl_d9f8c7',
  signers: [
    { email: 'user@customer.com', role: 'Signer1' }
  ],
  webhooks: {
    url: 'https://api.yoursaas.com/webhooks/mohor',
    events: ['envelope.completed']
  }
});

// Returns a secure URL to drop into the Web Component
console.log(envelope.embedUrl);

Architected for absolute reliability.

Stop debugging failed webhooks and corrupted PDFs. We built the infrastructure you actually want to integrate.

Bulletproof Webhooks

Backed by heavy-duty Redis queues. We guarantee delivery with exponential backoff, dead-letter queues, and manual dashboard replays.

Flawless PDF Engine

Native in-memory PDF manipulation. We don't just overlay images; we structurally flatten the document and apply cryptographic PAdES seals.

Drop-in Web Component

Embed our signing UI directly in your React, Vue, or Angular app using a Shadow DOM component that won't break your global CSS.

Pay per envelope. Keep your margins.

No seat-based licensing. No hidden bandwidth or storage fees.
