How to delete list item using SharePoint Online 2013 Rest API in C# -


i trying delete list item sharepoint 2013 online using rest apis c# managed code.

here's essence of code:

using (var client = new webclient()) {     client.headers.add("x-forms_based_auth_accepted", "f");     client.credentials = myspcreds;      client.headers.add(httprequestheader.contenttype, "application/json;odata=verbose");     client.headers.add(httprequestheader.accept, "application/json;odata=verbose");      client.headers.add("x-http-method", "delete");     client.headers.add("if-match", "*");      var requesturi = new uri("https://mysharepointsite.../_api/web/lists/getbytitle('mylist')/items(123)");      client.uploadstring(requesturi, string.empty); }

i'm getting 403 permission denied, using similar pattern able create list item. using credentials webclient sharepointonlinecredentials object. sharepoint site administrator.

so, wondering if have syntax/approach wrong. can verify code above "should" work assuming don't have permissions issues?

ok, found solution:

the client headers need include form digest:

client.headers.add("x-requestdigest", getformdigest());

to form digest, can use code:

    private string getformdigest()     {         var webclient = new webclient();         webclient.headers.add("x-forms_based_auth_accepted", "f");         webclient.credentials = this.credentials;         webclient.headers.add(httprequestheader.contenttype, string.format("application/json;odata=nometadata"));         webclient.headers.add(httprequestheader.accept, string.format("application/json;odata=nometadata"));          var uri = new uri(this.sharepointbaseurl);         var endpointuri = new uri(uri, "_api/contextinfo");         var result = webclient.uploadstring(endpointuri, "post");         jtoken t = jtoken.parse(result);          //use if odata = nometadata         return t["formdigestvalue"].tostring();          //use if odata = verbose         //return t["d"]["getcontextwebinformation"]["formdigestvalue"].tostring();     }

note: credentials tricky too, here's code that:

        var securepassword = new securestring();         foreach (var c in mypassword)         {             securepassword.appendchar(c);         }          this.credentials = new sharepointonlinecredentials(myusername, securepassword);
