Assigning Term Store Administrator on SharePoint Online using CSOM

Question

I am trying to setup a SharePoint Online Site Collection 100% programmatically via the CSOM in a .Net application.

I have been able to create the Site Collection itself, sub-sites and lists, but I am unable to create a new Taxonomy Group and Sets since my user is not assigned as the Term Store Administrator. If I assign myself as the Term Store Administrator through the Term Store Management Tool UI my code works exactly as I need it to.

Is there a way to assign a user as the Term Store Administrator only using the c# object model? Assume the context is running under a user that has sufficient rights to do this.

Answer 1

AFAIK there is no way to assign a user as TermStore Administrator using CSOM. But one thing you could do is to create a new user (similar to service account) and make that user TermStore Administrator. Run the code to create term group under the context of that user.

using (ClientContext clientContext = new ClientContext("https://yoursite.sharepoint.com/"))
{
    SecureString passWord = new SecureString();

    foreach (char c in "yourpassword".ToCharArray()) passWord.AppendChar(c);

    clientContext.Credentials = new SharePointOnlineCredentials("[email protected]", passWord);//Pass credentials of the new user you have created
}
