SharePoint REST API with fetch().then() and Ajax()

Using ajax

$.ajax({ url: "https://mysite.sharepoint.com/_api/web/lists/getbytitle('list')/items(" + id + ")", method: "GET", headers: { "Accept": "application/json; odata=verbose" }, success: function (data) { console.log(data.d.results); } });

Using fetch() and then()

payload = { method: 'GET', headers: { "Accept": "application/json; odata=verbose" }, credentials: 'same-origin' // or credentials: 'include' } fetch("https://mysite.sharepoint.com/_api/Web/Lists/GetByTitle('list')/items?$select=ID,Title", payload) .then(response => response.json()) .then((data)=>{ console.log(data.d.results) })

Send E-mail from javascript using REST API - SharePoint

In SharePoint 2013 we can send emails using REST API where we can utilize SP.Utilities.Utility.SendEmail for doing the job. 

Note: The recipient is limited to a valid SharePoint user for security reasons.

function sendEmail(from, to, body, subject) { //Get the relative url of the site var siteurl = _spPageContextInfo.webServerRelativeUrl; var urlTemplate = siteurl + "/_api/SP.Utilities.Utility.SendEmail"; $.ajax({ contentType: 'application/json', url: urlTemplate, type: "POST", data: JSON.stringify({ 'properties': { '__metadata': { 'type': 'SP.Utilities.EmailProperties' }, 'From': from, 'To': { 'results': to }, 'Body': body, 'Subject': subject } }), headers: { "Accept": "application/json;odata=verbose", "content-type": "application/json;odata=verbose", "X-RequestDigest": jQuery("#__REQUESTDIGEST").val() }, success: function(data) { alert('Email Sent Successfully'); }, error: function(err) { alert('Error in sending Email: ' + JSON.stringify(err)); } }); } $(document).ready(function () { SP.SOD.executeFunc('sp.js', 'SP.ClientContext', SendEmails); }); function SendEmails() { var from = 'info@domain.com', to = 'toUser@domain.com', body = 'Email using REST API', subject = 'Email FYI'; sendEmail(from, to, body, subject); }

Note: You can add 'CC' and 'BCC' property also to send email, property 'results' having array.
