SharePoint Online – How to Call Web API (Cross Origin)

Let’s see how to call Cross Origin Web API, which insert item in SQL Server Database.

Note that here key important thing is Web API, which accepts Cross Origin Request, and insert data into SQL Server. If you are not aware about how to create Web API using CORS, please check my article on How to Create WEB API using CORS.

This article will help you to call Web API using jQuery (web API insert Data into SQL Server Database)

I have created Page in Pages Library named “AddEmployeeSQL.aspx”

I have also created CustomScript named folder inside Style Library, which will hold webapi.txt – custom txt file, which includes jQuery and html content.

Content For webapi.txt File is as below.

<script src=""></script>

<div style="font-family:Verdana;font-size:11px">
    <h3>SharePoint Online - WebAPI - SQL Insert Operation</h3>
                <td>Name : </td>
                    <input type="text" name="txtName" class="txtName" />
                <td>Email : </td>
                    <input type="text" name="txtEmail" class="txtEmail" />
                <td>Contact No: </td>
                    <input type="text" name="txtContact" class="txtContact" />
                    <input type="button" value="Create" id="btnSave" />
                    <div id="loadingPanel" style="color:green; font-weight:bold;display:none;">Data Saving...</div>
    $(document).ready(function () {

        $('#btnSave').click(function () {

            var name = $('.txtName').val();
            var email = $('.txtEmail').val();
            var contact = $('.txtContact').val();

            $.post("", { Name: name, Email: email, ContactNumber: contact })
                .fail(function () {
                    alert("An Error Occured while saving record.");
                .done(function (data) {
                    alert("Sucess: " + data);

Now save this code in Webapi.txt (you can give your preferred name to file) file and upload it to Custom Script folder

Next Edit AddEmployeeSQL.aspx Page and add Content Editor Web Part.

Now Edit Content Editor Web Part and assign script reference

Save Page (check in and Publish it) and we are ready to check functionality.

Fill required Information and Click on Create Button.

You can see it will create record in SQL Server Database.

Hence, we can conclude that it’s really very easy to use Cross Origin Web API and using SharePoint Online jQuery Method.


How To Create A Hub Site in SharePoint Online

To Create Hub Site in SharePoint Online follow below steps

Crete SharePoint Site

I have created SharePoint Site URL:

Now Open SharePoint Online Management Shell and run below commands

Connect-SPOService -Url ""    

Make Sure you need to pass admin site url in my case it is “nrsharepoint-admin” while connecting using SPOService

It will ask your Credentials for the site.

Once you are able to login add below powershell commnad to register your given site as Hub Site.

Register-SPOHubSite -Site ""   

Once you run above command it will ask you Principals[0]: parameter value do not pass anything for that value.

After Successfully execution of commnad it will Convert or Connect Existing Site to Hub Site
