It helps you to electronically secure your documents by applying Text, Stamp, QR-Code, Barcode, Image and Digital Signatures. New version of GroupDocs.Signature Cloud 19.5 is released.

Please check the detailed release notes of this version to get an idea about all the new features/enhancements made in this release.

What’s New

API Version - Introduced API version V2

How it Works

The major change in this release is the introduction of V2 API version, it is all new API version. It is more simplified API with less methods and options. Also, it has more optimized and refined internal architecture. In this version, the API includes methods for working with cloud storage. So you can perform storage operations using GroupDocs.Signature Cloud REST API instead of using separate API.

Here we will show you how GroupDocs.Signature Cloud V2 API version works and it is different than V1. We will add Barcode signature in a Word document using V1 and V2 by following these steps:

  • Retrieve Access Token
  • Upload source document to Storage
  • Add BarCode Signature to source document

You can notice from following cURL examples that we have used JWT authentication in V2 example. Please note OAuth 2.0 and URL signing request authentication methods of V1 API version are not supported in V2 anymore. Now, V2 API version supports JWT(JSON Web Token) authentication.

In new release method we used File method of the V2 API for uploading file to storage instead of GroupDocs.Storage Cloud method. And the last difference from following examples, but not least, in V2 a single API create is used for all supported signature types by passing signature details as parameter. However, in V1 we used to call different APIs for each signature type.

V2.0 Example
