How to access the "Create with shared Configuration" Button throught API?

Question

When I click on "Create Project" then I can either choose a template or click on "Create with shared configuration". Now my question is, how can i modify this "Create with shared configuration" button, that it shows a different dialouge than it does now, after you clicked on it. I thought of a plugin but didn't know how to access this button through an API.

Welcome @TimG1367

There isn't a way to modify the funcionality of this button, rather using the API for it, which could be found in this article: https://community.atlassian.com/t5/Jira-articles/Jira-Cloud-Automation-Create-a-project-with-shared-settings-from/ba-p/1970419

@TimG1367  - Currently, Jira does not provide direct API support for creating projects using the "Create with Shared Configuration" option.

While you cannot directly replicate the "Create with Shared Configuration" option through the API, you can achieve a similar outcome by manually setting up the project and reusing the same schemes as another project.

* Use the /rest/api/3/project/{projectIdOrKey} endpoint to retrieve the schemes associated with an existing project that you want to copy. This will return information about the project, including its IDs for workflow schemes, permission schemes, issue type schemes, etc.
* Use the respective API endpoints for updating the project's configurations, use schemes ID in body. Here are the end points

PUT /rest/api/3/project/{projectIdOrKey}/permissionscheme
PUT /rest/api/3/project/{projectIdOrKey}/notificationscheme
PUT /rest/api/3/project/{projectIdOrKey}/issuetypescheme
PUT /rest/api/3/project/{projectIdOrKey}/workflowscheme
PUT /rest/api/3/project/{projectIdOrKey}/fieldconfigurationscheme

JSON Body

{
"id": "" // scheme ID from the source project
}

Hope this helps!
