Signus API

Migrate from DocuSign to Signus

Move your eSignature workflows to Signus without rebuilding your integration. Keep your existing API logic, switch the endpoint, and upgrade to an AI-native agreement platform.

// The only line that changes

const apiBaseUrl = "https://api.docusign.net/restapi";
const apiBaseUrl = "https://api.signus.ai/restapi";

// Everything else stays exactly the same

new ApiClient
