About SignNow

SignNow allows you to embed legally-binding e-signatures into your app, CRM or cloud storage. Send documents for signature directly from your website. Invite multiple signers to finalize contracts. Track status of your requests and download signed copies automatically.

This is a two module application which consists of the client-lib library and the example-app module. The client-lib library is used to interact with SignNow API. It covers all the authentication routines, request building and provides simple DTO objects to use in your applications. The second module, example-app, is a Spring Boot application which contains implementation examples of SignNow API use-cases.
