How do embedded signatures work?

Instead of directing people to SignWell to sign your document, the optional embedded signing feature allows users to fill out and sign your document directly on your website or app.

Create a better user experience, and reduce the risk of losing users in a multi-step, multi-site onboarding process. Your platform, our signatures: quick and hassle-free.

What is an e-signature API?

The SignWell e-signature application programming interface (API) allows you to automate signature requests online. Integrate the API into your web or app code to create, fill out, or send documents to be electronically signed.

Our e-signature API helps you quickly and securely request signatures and automate your workflows to create a simple and seamless signing experience.

Automate workflows

Get your documents signed quickly and hassle‑free.
When it comes to getting a document signed during a multi-step online process, a smooth, simple, and automated user experience is the difference between moving forward with your day, and manually chasing down a signature via email (or worse, paper). Imagine the simplicity of SignWell e-signatures embedded into your website or web application. No extra steps, no hoops to jump through.

Automate workflows and create a seamless e-signature experience that gets you and your people moving forward together with ease. You create and design it, we provide the tech and the developer support to get users signing quickly within your platform.

API includes

We're here to simplify your signature process

The SignWell API includes:

e-Signature Integration

Embedded requests and signatures

Easily integrate SignWell into your website or application — users can fill out and sign your document directly on your platform for seamless, one-stop signatures.

Automated Forms

Automate your workflows for hassle-free signing

We support multiple signing workflows and scenarios — create reusable templates that can be populated with user-filled fields, and make the automatic signature process easier and faster, for both the signers and the senders.

Secure & Compliant e-Signatures

Legally-binding signatures at the click of a button

The SignWell API is compliant with U.S. and international e-signature laws, meaning it's as legally binding as pen-and-paper documents. Signed documents are archived and protected from further changes, so you can rest easy knowing your documents are secure.

Easy and Flexible Configurability

Easily white label for a branded signing experience

The SignWell API offers all the capabilities of our e-signature product, personalized for your business. Automated white labeling allows you to seamlessly match your brand, creating an effortless user experience.

Pay-As-You-Go Pricing

Pay per document at an affordable rate

The SignWell API starts at $0.75/document with a pay-as-you-go system, so you only pay for the signature requests that you actually use — no more locked-in plans paying for volume that you don't need. Plus, we give you the first 25 API documents each month free (no other e-signature API does this!)

Reliability & Uptime

Reliable service for non-stop signing

With our systems running at multiple physical locations, SignWell offers 99.99% uptime. Our operation team regularly monitors services and operations to provide you with the highest availability possible.

Developer Documentation

Clear and easy developer documentation

Written by developers, for developers. We constantly update our documentation to keep it current, and our REST-based API is reviewed and edited by external third parties for accuracy and clarity.

Knowledgeable Support

Developer-focused API support

When creating a customized signing experience, developer support is key — we offer dedicated developer support for all SignWell API customers. We're here to provide examples and make it easy for all developers to build out the integration, no matter their skill level.
