Adding a Content Type to a document library using Send HTTP Request

[landonjochim]

Hello Community, 

I am wondering if it is possible to add an existing content type to a document library using the SharePoint Send HTTP Request? I have a flow that gets a list of new sites, and I would like to automatically cycle through those and add a content type to their default document library.  

If this is not possible, is it possible to add an existing managed metadata column to a document library using the Send HTTP Request?

Thanks for the help. Always appreciated.

Hi @landonjochim,

If the content type already exists on the site and on the library the management of content types is allowed you could use the addavailablecontenttype method to add it.

Below is an example of that:

Thanks for the response that helped! Is there a method to set the default content type?

Hi @landonjochim,

It might be possible via the uniqueContentTypeOrder method:

But I haven't tried that myself to be honest.
