My app page doesn't have __REQUESTDIGEST on page elements. How do I get this value from sharepoint API ? I used this codes but return 403 Forbidden error

var formDigest;
        url: hostUrl + "/_api/contextinfo",
        method: "POST",
        headers: { "Accept": "application/json; odata=verbose" },
        success: function (data) {
            formDigest = data.d.GetContextWebInformation.FormDigestValue
        error: function (data, errorCode, errorMessage) {

If you are authenticated then it is:

_spPageContextInfo.webAbsoluteUrl + '/_api/contextinfo'

All Modern Experiences do not have that hidden #__REQUESTDIGEST either, so you have to call the /contextinfo endpoint

I suggest to use a window.setInterval function to always make sure you have a valid digest in a global variable.
Saves you from requesting a new value before every REST call and thus simplifies your code.

From an App:


  • First thanks for your comment. I'm authenticated. I retrieve all of lists. But when I'm trying to get digest it returns forbidden error. Do you think webAbsoluteUrl is the same Sharepoint Host url ? Like project.sharepoint.com/sites/appsite ?? Nov 4, 2016 at 8:57
  • Ah, are you working from an App and not straight from the Host Web? You then need to go through the request executor, I don't have that code at hand. Nov 4, 2016 at 8:59
  • Yes I'm working on App. But thanks any way. I'm searching request executor now. Nov 4, 2016 at 9:32
