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

[ryleybauer]

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

I'm having exactly the same issue.

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!

Hi @ryleybauer !

Did you ever find any solution for this?

[ryleybauer]

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. 

[ArneBerg]

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. 

[ryleybauer]

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

 $baseURL = "ryleybauer"

 $adminURL = ' https://' + $baseURL + '-admin.sharepoint.com'

Thanks Angus! That's not even something I thought to try by changing the API version! +1 and solution for you!

[ArneBerg]

Thanks a lot @ryleybauer !! Really helpful 😊

Do you know if there are any way to include default values set on folders?

[ryleybauer]

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. 

[MatthiasVeelaer]

@AngusWalker May I ask what your, you don't have to actually give the uri, siteuri and such was because I am trying the exact same but for me it's not working and I think that it has to do with the way I use my uri. Thanks

[AngusWalker]

@MatthiasVeelaer 
Here is my final code from one of my runs. I confuscated the ids but added what they should be.

--batch_ausenco-0001
Content-Type: application/http
Content-Transfer-Encoding: binary

POST sites/xXthisxx-xisx-thex-site-xxxxidxxxxxx,xxthisxx-xisx-thex-site-xwebxidxxxxx/lists/xxthisxx-xisx-thex-xidx-xofxthexlist/contentTypes/addCopyFromContentTypeHub HTTP/1.1
Content-Type: application/json
Accept: application/json
Content-Length: 60

{"contentTypeId":"0x01010077thisxisxthexcontentxtypexidxxx"}

--batch_ausenco-0001--

the tricky one I think is the Web Id.
I got that from here:

Hope this helps

[MatthiasVeelaer]

@AngusWalker I will definitely give it a try 🙂 May I ask, what is the difference between the site id and the site webid? and your url. Is that the one oif your sharepoint environment then? Like the sharepoint domain in which your site is located?

[AngusWalker]

You can ask, but I haven't a Scooby.
I don't know why there are two different IDs or why it needs both, or where I found that you need both.
I think I just found it by trawling here and Stack Exchange. 🙂
