Set Site Logo Description in SharePoint using REST API

The example in this topic show how to use REST API to Set Site Logo Description in SharePoint
  • REST-API is based on OData (Open Data) Protocol and hence it doesn't require any dll or JS library to run the commands on the SharePoint objects.
  • REST-API calls require proper end-point URL and proper Header implementation in your REST call.

How to use SharePoint REST API?

  • Note: This is just a sample, you can go ahead with your implementation.
  • You can also use this method in your SPFx Component.
  • Open your Site. Create a webpart page.
  • Put a Content Editor Web part and a Script Editor Web part on it.
  • Webpart page content editor and scipt editor
  • I have added below Html in Content Editor webpart. You can replace MainFunction with your actual method name.

    <button onclick="MainFunction();" type="button">Click me​</button>

  • And below references in Script Editor Webpart. ScriptFile.js is a JavaScript file where you can keep below function i.e. your actual logic.

    <script src="https://MyServer/sites/SiteCollection/style library/js/ScriptFile.js"></script>

  • Once you are done with setting your page, click on the button and your method should get executed.

  • function SetSiteLogoDescription()
  • {
  •        $.ajax
  •         ({
  •             // _spPageContextInfo.webAbsoluteUrl - will give absolute URL of the site where you are running the code.
  •             // You can replace this with other site URL where you want to apply the function
  •            
  •               url:  _spPageContextInfo.webAbsoluteUrl + "/_api/web/",
  •             type: "POST",
  •                   data: JSON.stringify({
  •                              '__metadata': {
  •                                  // Type that you are modifying.
  •                                  'type': 'SP.Web'
  •                              },
  •                              "SiteLogoDescription": 'Site Logo Description Updated'
  •                          }),
  •               headers:
  •             {
  •                 // Accept header: Specifies the format for response data from the server.
  •                 "Accept": "application/json;odata=verbose",
  •                 //Content-Type header: Specifies the format of the data that the client is sending to the server
  •                 "Content-Type": "application/json;odata=verbose",
  •                 // IF-MATCH header: Provides a way to verify that the object being changed has not been changed since it was last retrieved.
  •                 // "IF-MATCH":"*", will overwrite any modification in the object, since it was last retrieved.
  •                 "IF-MATCH": "*",
  •                 //X-HTTP-Method:  The MERGE method updates only the properties of the entity , while the PUT method replaces the existing entity with a new one that you supply in the body of the POST
  •                 "X-HTTP-Method": "PATCH",
  •                 // X-RequestDigest header: When you send a POST request, it must include the form digest value in X-RequestDigest header
  •                 "X-RequestDigest": $("#__REQUESTDIGEST").val()
  •             },         
  •                success: function (data, status, xhr) {
  •                      console.log("Success");
  •                      },
  •                error: function (xhr, status, error) {
  •                      console.log("Failed");
  •                }
  •         });
  • }
