I'm looking to integrate a document management system such as DocuSign with FileMaker. I would like to be able to send a PDF generated within FMP to a third party system so a link can be sent to a customer to view and digitally sign. This is not just the ability to draw a signature on an iPad or signing device, but a way to have a salesman send and handle the documents such as contracts and quotes without too many additional clicks. I suppose it would have to be some sort or API call (XM, email with attachment, etc.) that would go out to the 3rd party service and can then be tracked.
Any points in the right direction would be greatly appreciated.
