There are a lot of resources around that show how to do this, but I couldn’t find a comprehensive go-to link, so here we are.

You can create a SharePoint site using the REST API.  Here’s a fully baked example:

<!--
    SiteRequestForm.html: Collect information and create a site for the user.
-->

<సెంటర్>
<పట్టిక>
    <tr>
        <td>Site Name:</td>
        <td><ఇన్పుట్ రకము="text" పేరు="SiteName" ID="SiteName" /></td>
    </tr>
    <tr>
        <td colspan="2">
            <ఇన్పుట్ రకము="submit" ID="CreateSiteButton" విలువ="Create the Site" />
        </td>
    </tr>
</పట్టిక>
</సెంటర్>

ఉంది CreateSiteLogicContainer = {

    createSiteData: {
            "parameters": {
                __metadata: { "type": "SP.WebInfoCreationInformation" },
                Url: "Paultest1",
                శీర్షిక: "Paultest1",
                వర్ణన: "rest-created web by Paul!",
                భాష: 1033,
                WebTemplate: "sts",
                UseUniquePermissions: అబద్ధమైన
            }
    },

    createSite: ఫంక్షన్ () {

        jQuery.support.cors = నిజమైన;

        CreateSiteLogicContainer.createSiteData.parameters.Url = $("#SiteName").Val();
        
        $.ajax({
            url: "https://bigapplesharepoint.sharepoint.com/NBAIADev/_api/web/webinfos/add",
            పద్ధతి: "POST",

            headers: {
                "Accept": "application/json; odata=verbose",
                "content-type": "application/json;odata=verbose",
                "X-RequestDigest": $("#__REQUESTDIGEST").Val()
            },

            డేటా: JSON.stringify(CreateSiteLogicContainer.createSiteData),

            success: ఫంక్షన్ () { హెచ్చరించు("success"); },
            తప్పు: ఫంక్షన్ () { హెచ్చరించు("error"); }

        });
    },

    wireUpForm: ఫంక్షన్ () {
        $("#CreateSiteButton").క్లిక్(ఫంక్షన్ () {
            హెచ్చరించు("About to try and create the site.");
            CreateSiteLogicContainer.createSite();
        });
    }


}

CreateSiteLogicContainer.wireUpForm();

When successful, you get a JSON packet in response like this:

My key thoughts and learnings from this include:

• This approach uses jQuery.  నా విషయంలో, my jQuery library is located in “../plugins.”  You’ll want to change that to point to your favorite JQ location.
• You can copy and paste that whole snippet into a Content Editor Web Part on a page and it should work just fine.  You’ll want to change the end point of the API call and make sure you reference JQ correctly.
• The URL is relative to your API’s endpoint.  నా విషయంలో, it’s creating sub-sites underneath https://bigapplesharepoint.com
• You don’t need to provide a content-length. Some blog posts and MSDN document implies that you do, but happened for me automatically, which I assume is being handled by the $.ajax call itself.
• This line is required in order to avoid a “forbidden” response: "X-RequestDigest": $("#__REQUESTDIGEST").Val().  There are other ways to do it, but this is pretty nice.  I have lost the link to blog that provided this shortcut.  H/T to you, mysterious blogger!

Good luck and hope this helps someone out.
