Quick Start Example

JavaScript

// Using API Key
const response = await fetch('https://api.signquick.app/v1/documents', {
  headers: {
    'Authorization': 'Bearer sq__your_api_key_here',
    'Content-Type': 'application/json'
  }

API Key Types

sk_test_

Test Keys

Use test keys during development. No real documents are created and no charges apply.

sq__

Live Keys

Use live keys in production. All operations create real documents and count toward your quota.

Security Best Practices

Store API keys in environment variables, never in code.
Rotate keys regularly and revoke unused keys.
Use the minimum permissions required for each integration.
Monitor API usage for unusual patterns or spikes.

Start Integrating

Get your API key from the dashboard and start building in minutes.
