Add signing to your product without rebuilding the workflow around it.
Integrate e-signatures into your application with a RESTful API, embedded signing, and event-driven webhooks. Build on a platform designed for developer productivity.
Everything a developer needs to integrate signing.
Qik Sign provides the tools and documentation to add e-signature capabilities to your product with minimal friction.
RESTful API
Create, send, and manage envelopes programmatically. Standard HTTP methods and JSON request/response bodies.
Embedded signing
Keep the signing experience inside your application using our API. Signers never leave your product flow.
Webhooks
Receive real-time callbacks for envelope events. Trigger workflows, notifications, and updates without polling.
Sandbox environment
Build and test in a dedicated sandbox that mirrors production behavior. Move to production when your integration is ready.
API documentation
Comprehensive documentation with endpoints, parameters, request examples, and error handling guidance.
Event-driven workflows
Connect signing events to your existing systems. Automate post-signing actions like data syncs and notifications.

Frequently asked questions
What APIs does Qik Sign offer?
Qik Sign provides RESTful API endpoints for creating, sending, and managing envelopes. You can create documents, add recipients, set signing order, and retrieve status and completion data programmatically.
Can I embed the signing experience in my application?
Yes. Embedded signing lets you keep the signing experience inside your application or website using our API. Recipients complete signatures without being redirected to an external page.
How do webhooks work?
Webhooks send HTTP callbacks to your server when envelope events occur — signed, declined, expired, or delivered. Use them to trigger downstream workflows without polling.
Is there a sandbox or test environment?
Yes. Developers can use our sandbox environment to build and test integrations before moving to production. The sandbox mirrors production API behavior.
What authentication is used?
API requests are authenticated using API keys. Consult the API documentation for authentication details, rate limits, and best practices.
What plans include API access?
API access and embedded signing are available on Business Lifetime, Business Plus Lifetime, and Enterprise plans. Standard Lifetime includes webhooks but not API or embedded signing.
