SignQuick API
Documentation

Authentication

All API requests require authentication using a Bearer token in the Authorization header. You can generate API keys from your dashboard settings.

Authorization: Bearer YOUR_API_KEY

curl -X GET https://signquick.app/api/documents \
  -H "Authorization: Bearer sq__abc123def456ghi789"

Error Handling

The API uses standard HTTP status codes to indicate the success or failure of requests. Error responses include a JSON body with details.

{
  "error": "validation_error",
  "details": [
    "fileName is required",
    "fileSize must be a positive number"
  ]
}

Rate Limits & Plan Quotas

API usage is subject to plan-based quotas. Document creation is metered monthly, and certain features require higher-tier plans.

Create, retrieve, update, and delete documents. Documents are the core resource in SignQuick representing PDF files uploaded for signing.

Create and manage multi-party signing requests. Send documents to multiple signers for electronic signature with email notifications.

Manage reusable document templates with pre-defined signature zones. Templates allow you to quickly create documents with consistent layouts.

Search across documents and signing requests with full-text search, filtering, and pagination.

Retrieve dashboard statistics, activity feeds, signing breakdowns, and monthly trends.

Subscribe to real-time events via webhooks. Receive HTTP POST notifications when documents are signed, requests are completed, and more. Business plan only.
