There are three main options for capturing signatures from a web application:
1. The Wacom Ink SDK for Signatures for Windows
This is a fast-development SDK for use on Windows PCs only. Its browser subcomponent, SigCaptX, is compatible with Chrome, Firefox and Edge for capturing signatures. The main SDK and the SigCaptX subcomponent must be installed on the end user's PC.
A basic license for this SDK is free and is provided in the GETTING STARTED document for the sample code. For more information on how to obtain the licence and its payable enhanced functionality, please see here.
2. The Wacom Ink SDK for Signatures for JavaScript
As the name implies, this is designed purely for use with JavaScript. It has two main advantages over the Signature SDK for Windows:
i) It is cross-platform i.e. not restricted to Windows
ii) It does not require the installation of any software on the client PC
There are some minor limitations on browser compatibility as explained in the README document for the sample code on GitHub.
NB: the ink SDK for Signatures for JavaScript is charged on a transaction basis, i.e. per signature, and in most cases the minimum number of transactions is 10,000 per year.
Sample code for this SDK is available at https://github.com/Wacom-Developer/signature-sdk-js.
All Wacom Signature SDKs can be downloaded under "Signature" here:

3. sign Pro PDF API
This API enables you to invoke sign Pro PDF via a JSON script or to embed positional text tags within the PDF itself. You can download a trial version of the sign pro PDF API here.
If you have any enquiries about costs on any of the above options, please contact your regional Wacom Sales Manager. If you don't know who this is, please contact the Wacom Solutions Team at solutions@wacom.eu for assistance, or use the "Submit a request" link at the top of this page.
