Implementing a Document Review and Signing Flow with Spring Boot and E-Signature APIs

In today's digital age, the ability to review and sign documents electronically has become a vital part of business operations. Integrating this functionality into your applications can save time and resources, enhance user experience, and ensure secure transactions. In this guide, we will explore how to implement a document review and signing flow within a Spring Boot application using popular e-signature APIs, such as DocuSign and HelloSign.

Understanding the Workflow

The typical document review and signing workflow consists of the following steps:

Document Creation: A document is generated that requires one or more signatories.

Review Process: The document is sent to relevant parties for review.

Signature Request: After approval, the document is sent for signatures.

Completion: Once all signatures are obtained, the document is finalized and stored.

Using Spring Boot as the foundation for your application, you can orchestrate this workflow seamlessly.

Setting up Spring Boot

Start by creating a new Spring Boot project. If you are familiar with Spring Initializr, you can easily generate a starter project and add dependencies for Spring Web to handle HTTP requests.

Integrating DocuSign API

1. Configure DocuSign Credentials

Register your application with DocuSign and obtain your API credentials (Client ID, Secret, and Account ID). These will be used to authenticate your API requests.

2. Create a Service Class

Create a service class to handle DocuSign API interactions. Use the docusign-esign library, add it to your project dependencies, and then implement methods for creating and sending envelopes.

Integrating HelloSign API

1. Configure HelloSign Credentials

Register your application with HelloSign and obtain your API key.

2. Create a Service Class

Create a similar service class to interact with HelloSign API. Add the hellosign-sdk to your project dependencies and implement methods for sending signature requests.

Finalizing the Document

Once the document is signed, you can implement a callback endpoint to receive notifications from the APIs about the completion of signatures. This endpoint will handle storing the finalized document and updating the application status.
