Slack application integration error

ryan_ae9k17

When I click on 'Connect to Slack' with the Confluence App,  I receive the following error in a dialog:

{"error":{"message":"Invalid or missing CSRF token","code":"INVALID_CSRF"}}

I am currently using the standalone Slack Application and not the browser version

Hi @ryan , welcome to the Community!

We often see this error when cross-site protection in browsers is in a strict mode. For example, Brave Browser's Shield functionality will block third-party cookies, which will lead to this CSRF token error.

If possible, I'd suggest trying the "Connect to Slack" flow in a vanilla or incognito Chrome window (extensions disabled) - by default, Chrome does not block this flow. If you have trouble getting the popup from Slack to go to the correct browser window, you could try signing into slack.com (the web app) from the incognito browser session first - then trying the login flow from the Confluence app in Slack should kick open a new tab in your incognito window rather than going to your system's default browser.

Otherwise, knowing which specific browser you're using, I can provide steps for creating an exception for the integration. This flow only needs to be completed once - after the connection is established, you don't need to use an incognito or continue with an exception in place.
