How to find custom Site WebTemplate ID in order to automate site creation Flow

[SoporteAcorde]

Hi!

I´m working on a Flow that will allow me to create a new SharePoint subsite on a list´s item creation. So far I have managed to get the Flow to work using the standard team site WebTemplate (STS#0) and the project WebTemplate ids (PROJECTSITE#0).

I´m using the "Send HTTP request to SharePoint" action that looks like this:

However I want to be able to create such sites using my own custom site template which I have already created and saved as such.

Here is the question:

I need to be able to locate the correct WebTemplate ID in order to feed that information to the HTTP action, I have followed several articles including this one: https://jamesdiblasi.wordpress.com/2013/08/17/sharepoint-2013-finding-your-custom-site-template-id/ in order to do so.

By following that I was able to retrieve what I though was my site´s custom Webtemplate ID which reads: 

"{662D1818-F781-416B-8474-DE74B9917DE1}#Acorde_projectTmpA"

However, when I change my Web Template from PROJECTSITE#0 to 662D1818-F781-416B-8474-DE74B9917DE1}#Acorde_projectTmpA the flow runs into an error. The output of the error shows the following:

{

"message": "Invalid file or arguments for the site template '662D1818-F781-416B-8474-DE74B9917DE1#Acorde_projectTmpA'.\r\nParameter name: WebTemplate\r\nclientRequestId: bd8074ce-8f8a-48e9-b729-37ca40aef70c\r\nserviceRequestId: a5a81f9f-3084-0000-497c-336584773c12",

"status": 400,

"source": "https://acordeor.sharepoint.com/sites/proyectos/_api/web/webinfos/add",

"errors": [

"-2147024809",

"System.ArgumentException"

]

}

Which, if I´m not mistaken, means that I´m entering a wrong value for my custom site WebTemplate. I have also tried to get this ID using PowerShell but it appears that the sites I have created using this template are not showing any WebTemplate ID:

Please guide me on where to find the custom web template ID in order to use it in my flow.

Thanks in advance.

have you tried: {662D1818-F781-416B-8474-DE74B9917DE1}

Hi,

I answered to this post a few days ago but today I´m noticing that my response is not there so here it is again.

I did try with {662D1818-F781-416B-8474-DE74B9917DE1} but the errors is the same. Today I talked to a Microsoft representative that told me that custom site template IDs are not supported which sounds weird to me since not been able to automate site creation with your own customized sites would be a big missed opportunity if you ask me.

Any suggestions are more than welcome.

Thanks

it is supported, i do not do it this way.

i use plumsail actions, look them up they are very cheap and take all this complexity away

Thanks @Gristy  but I´ve just figured it out.

Here are the steps as a future reference:

• First your need to run the following powershell in order to get your Template ID. Bear in mind that the list is affected by the language used when the template was saved, so change the language ID in case you use other languages besides English:

$Username = Read-Host -Prompt "Please enter your username"

$Password = Read-Host -Prompt "Please enter your password" -AsSecureString

$Site = "Site URL"

$Context = New-Object Microsoft.SharePoint.Client.ClientContext($Site)

$Creds = New-Object Microsoft.SharePoint.Client.SharePointOnlineCredentials($Username,$Password)

$Context.Credentials = $Creds

#List Custom Templates

$Templates = $Context.Site.GetWebTemplates("1033","0")

$Context.Load($Templates)

$Context.ExecuteQuery()

$Templates | Where {$_.Name -like "*{*" } | Select Name, Description

Alternatively, you can used the method explained earlier, where you inspect the template from Site Contents in order to get the Template ID.

• Second, update the Flow in order to match the language ID of your Template, in this case:

{ 'parameters':
{ '__metadata':
{ 'type': 'SP.WebInfoCreationInformation' },
'Url':'@{triggerBody()?['Title']}',
'Title':' @{triggerBody()?['Title']} ',
'Description':'@{triggerBody()?['Title']}',
'Language':'1033',
'WebTemplate':'{662D1818-F781-416B-8474-DE74B9917DE1}#TEMPLATE_projectA',
'UseUniquePermissions':false
}
}

In my case, I was using language ID 3082 (Spanish) whereas my Template language was 1033.

Hope it helps somebody else.

So once i find my custom template id, what do i use for the site address field at the beginning of the http request if i am not creating a subsite? Our company has decided to not use Subsites out of fear that Microsoft will be eliminating them at some point based on how Modern Sites now have the Hub system.
