## Automate Your Signing Workflow

From single documents to bulk operations. See the [e-signature API](https://www.turbodocx.com/e-signature-api.md) for more options. Production ready.

### Single document: sequential signing

```typescript
import { TurboSign } from '@turbodocx/sdk';

// Send NDA for sequential signing
const result = await TurboSign.sendSignature({
  fileLink: 'https://storage.example.com/ndas/employee-nda.pdf',
  documentName: 'Employee NDA - John Smith',
  recipients: [
    // Employee signs first
    { name: 'John Smith', email: 'john@example.com', signingOrder: 1 },
    // HR signs second
    { name: 'HR Manager', email: 'hr@company.com', signingOrder: 2 }
  ],
  fields: [
    {
      type: 'signature',
      recipientEmail: 'john@example.com',
      template: { anchor: '{EmployeeSignature}', placement: 'replace' }
    },
    {
      type: 'signature',
      recipientEmail: 'hr@company.com',
      template: { anchor: '{HRSignature}', placement: 'replace' }
    }
  ],
  webhookUrl: 'https://yourapp.com/webhooks/signature-status'
});

// Returns: { success: true, documentId: "...", message: "..." }
// Webhook notifies your app when each signer completes
```

### Bulk signing

```typescript
import { TurboSign } from '@turbodocx/sdk';

// Send 100+ employment contracts in one batch
const employees = await database.getNewHires();

const bulkSigningRequests = employees.map(employee => ({
  fileLink: `https://templates.com/${employee.contractType}.pdf`,
  documentName: `Employment Contract - ${employee.name}`,
  recipients: [
    { name: employee.name, email: employee.email, signingOrder: 1 }
  ],
  fields: [
    { type: 'signature', recipientEmail: employee.email,
      template: { anchor: '{EmployeeSignature}', placement: 'replace' } }
  ],
  webhookUrl: `https://yourapp.com/webhook/employee/${employee.id}`
}));

// Send all contracts in parallel
const results = await Promise.allSettled(
  bulkSigningRequests.map(req => TurboSign.sendSignature(req))
);

const successful = results.filter(r => r.status === 'fulfilled');
console.log(`Sent ${successful.length} contracts for signature`);
```
