Sync SharePoint master content type gallery with http request on a newly created site

I have a flow I've been working on that deploys a SharePoint site, and creates a few lists based on custom content types in the global content type hub.

I have the following steps to create a list and apply a content type:

After some experimenting, I have confirmed that the above works, but only with the default content types. i.e. "0x0103" is fine, but my custom "0x0100AC4AE1EDCA551B478B245F71BB69####" content ID does not work, it's a BadGateway or Unauthorized error.

I've determined that the content type hub is not auto-publishing to newly created sites. If I send an http request to add one of my new content types to the list, I cannot. But, if I manually add the content type to a list, then remove it from the list and re-attempt the http request, it works. Thus, I've concluded I need to pull in the global content type gallery somehow.

I found this article about the new content type publishing What’s changed in content type publishing - Microsoft Support
contentType: addCopyFromContentTypeHub - Microsoft Graph v1.0 | Microsoft Learn

I've set up the http request and attempted the following URIs, but I'm getting invalid endpoint errors. Does anyone know what I'm doing wrong on this request?

_api/site/contentTypes/addCopyFromContentTypeHub

_api/web/contentTypes/addCopyFromContentTypeHub

/contentTypes/addCopyFromContentTypeHub

/contentTypes/addContentTypesFromHub

Hi @AngusWalker , sorry I didn't see this.

I couldn't get around this issue, but I just changed my approach and it was much better. Check out my blog post on how to export the existing site as a template so you don't have to worry about syncing the content types!

No unfortunately I wasn't able to. But, I accomplished my goal of deploying a site with a few lists that had specific content types by creating a site template that had lists using the global content types.

Thank you for your answer! Great that you were able to deploy a site with specific lists and content types by creating a site template that utilized the global content types. Could you please tell me more about how you accomplished this? Thank you!

I managed to add my content types using a $batch command.
I think the biggest issue I had was realising I needed to force the v2.1 version of the api.

I wrote a blog post about how to deploy the templates from an existing site.
https://bauerautomate.com/blogs/post/powershell-clone-site
Once you have the template available, it's a single HTTP request to create the group, apply the template and even join to the hub:

I learned that the creation option has the same leading 20 characters for everyone.

The design ID is included in the powershell output when you generate the template. You can also open a new powershell window

Hi @ArneBerg I don't think you can, but you could add another step for "update file properties only) might work if you're asking about applying standard metadata.
