This assumes Kong has been secured with Role Based Access Control (RBAC) and you have created your Kong-Admin-Token. The following curl command can be used to list the endpoints that can be used with the API.

curl --header "Kong-Admin-Token: abc123" --request GET "https://kong.example.com/endpoints"

Something like this should be returned. Notice that the /workspaces/<workspace name> endpoint can be used.

{
    "data": [
        "/",
        "/acls",
        "/acls/{acls}",
        "/acls/{acls}/consumer",
        "/workspaces",
        "/workspaces/{workspaces}",
        "/workspaces/{workspaces}/meta"
    ]
}

The following curl command can be used to list the workspace named "default".

curl --header "Kong-Admin-Token: abc123" --request GET "https://kong.example.com/workspaces/default"

This could also be seen using the Kong web browser console. Notice the default workspace has Set up Dev Portal.

Something like this should be returned. Notice portal: false, which means the Kong Dev Portal is not enabled for the "default" workspace.

The following curl command can be used to enable the Kong Dev Portal for a workspace.

curl --header "Kong-Admin-Token: abc123" --request PATCH "https://kong.example.com/workspaces/default" --data "config.portal=true"

Reissue the following curl command.

curl --header "Kong-Admin-Token: abc123" --request GET "https://kong.example.com/workspaces/default"

Notice portal: true, which means the Kong Dev Portal is now enabled for the "default" workspace.
