When integrating with Atlassian SCIM at Settings > Integrations, you need to provide your Atlassian subdomain.
You can access your Atlassian subdomain from the following URL:
Copy the subdomain (highlighted in the sample image in red) and provide it below in Swifteam.
Make sure you copy the entire value.
If your company's Atlassian URL is https://<subdomain>.atlassian.net, you would just provide the subdomain and not the full URL.
