问题
My company is building a browser-javascript app. We want to use the docusign api via browser javascript without using a proxy server (our clients really don't like paying for extra proxy servers). So if you can implement CORS or JSONP for your api, it will be much easier for us to convince our clients to purchase and use docusign. Thanks a lot!

DocuSign does not support CORS (Cross-Origin Resource Sharing) in its platform. There are too many potential security risks with CORS and for DocuSign to maintain its extremely high level of security and certification compliance it can not support CORS.
