CORS (Cross-site scripting) Issue with Chrome

edited Jul 29, 2016 3:05PM in CRM On Demand - Web Services Integration (MOSC) 6 commentsAnswered

I've partially built out a web app and am running into issues using the REST API to authenticate and perform basic GET requests. It works in Internet Explorer, but Chrome more strictly adheres to CORS and throws errors at preflight "No 'Access-Control-Allow-Origin' header is present on the requested resource."

I opened a support ticket assuming they could add my web server's domain to my CRM instance's 'allow-origin' list but it got tagged as a bug and sent to the development team. I should still be able to perform simple GET calls even without the header addition, but Chrome disagrees. Has anyone successfully created a browser accessible web app that can access CRM data via the REST APIs?
