Error 400 CORS Headers
Hi There, We keep running in to this error: XMLHttpRequest cannot load No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'https://dev01.<valid_url>.com' is therefore not allowed access. The response had HTTP status code 400. I have added everything on my sites headers to allow this but it appears to be on your side. any ideas? Ben
Error 400


Please take a look at the article on Error 400 posted in the forums under PaymetsJS. This gives some details what to look for when encountering this error. Usually the "No 'Access-Control-Allow-Origin'" error is a red herring. You can drill down further into the console and look for the next "Object", as this may contain information into the exact issue. Please let us know if this helps, if not please feel free to provide additional details to this forum post or contact us at [email protected].
