Signing as an API.

Everything the Sign10X app does, your application can do too — with scoped credentials and event-driven callbacks.

Try the sandbox console Integration guide Read the docs Create API keys

REST API

Predictable resources for documents, requests, recipients and fields.

API keys

Separate test and production keys. Secrets are shown once.

Webhooks

Signed deliveries for every lifecycle event, with retries.

Embedded signing

Host the signing experience inside your own application.

Usage tracking

Requests, errors, latency and rate-limit events per key.

SDK-friendly

Plain JSON over HTTPS — works with any language.

Create a signature request

const res = await fetch(
  "/api/public/v1/signature-requests",
  {
    method: "POST",
    headers: {
      Authorization: `Bearer ${process.env.SIGN10X_API_KEY}`,
      "Content-Type": "application/json",
    },
    body: JSON.stringify({
      document_id: "doc_123",
      signers: [{ name: "John Smith", email: "[email protected]" }],
    }),
  },
);

const request = await res.json();
// { "id": "req_123", "status": "sent" }
