Integration between JIRA and Active Workspace Edited

[saranya]

I am trying to establish a connection between Jira and active workspace using REST API,
when I do so I am getting CORS error.

I have followed the https://community.atlassian.com/t5/Answers-Developer-Questions/Cross-Origin-Resource-Sharing-with-JIRA-REST-API-and-Javascript/qaq-p/484801 but it dosent seem to be working. can you please help?

Is there a file on jira server where I can make changes to "Access-control-allow-origin" , is so can you please let me know the file name.

Could you explain what this has to do with Atlassian?  Proview is not one of their products, or an app in the marketplace

There's not quite enough information in the new question, but the first thing to work through is https://community.developer.atlassian.com/t/cors-error-with-rest-api/27354/3
