# Start building eSignature integrations

The SignNow REST API empowers users to deliver an exceptional eSignature experience for signers, preparers, and senders. Pre-fill documents, create embedded branded workflows for multiple signers, request payments, and track signature status in real-time. Ensure signing is simple, secure, and intuitive on any device.

## What you can do with the SignNow API

### Embed signing in your app

Let signers complete documents inside your product, with no redirects and no SignNow branding.

### Let users send from your app

Give them a full prep flow: upload a document, assign recipients and fields, send the request — all in your UI.

### Prepare documents in your interface

Drop in the embedded editor so users can add and position fields before sending.

### Put your brand on everything

Signing pages, emails, logos, colors, fonts. Your users never see SignNow.

### Generate documents from data

Upload a `.docx` with tags, populate it from your data, get a signature-ready PDF.

### Automate the whole agreement flow

REST endpoints, SDKs, and webhooks for real-time signing events, plus Development Mode to test end to end before you ship.
