Suggestions on electronic signature development
There are a few requests on this that aren't specific.
It would be profoundly useful to either open the platform, perhaps by creating an API, or point to available open source scripts that would advance to this platform. There seem to be a few approaches to connecting this service to a 3rd party eSignature API service, where either a template could be called or triggered. I use Signnow for it's value driven pricing model, however any integration with an eSignature service would make the any pricing model that much more attractive.
