Here we will discuss how we can delete all items from SharePoint online list using Rest API. I have a list which has few items inside the list in my SharePoint online site. The list looks like below:
Below is the code which we can add into a script editor web part which we can add in a web part page.
Here is the first function we are getting the items and then we are building the rest API URL for deleting an item and passing it to the deleteItem(URL) method.

The full code looks like below:
<script src=”https://ajax.googleapis.com/ajax/libs/jquery/1.11.2/jquery.min.js”></script>
<input type=”button” id=”btnDeleteAllItems” value=”Delete All Items” />
<script>
$(function () {
bindButtonClick();
});
function bindButtonClick() {
$(“#btnDeleteAllItems”).on(“click”, function () {
$.ajax({
url: _spPageContextInfo.webAbsoluteUrl + “/_api/web/lists/getByTitle(‘Announcements’)/items”,
type: “GET”,
headers: {
“accept”: “application/json;odata=verbose”,
},
success: function (data) {
var items = data.d.results;
$.each(data.d.results, function (key, value) {
var id=value.ID;
var url = “/_api/Web/Lists/getByTitle(‘Announcements’)/getItemById(“+id+”)”;
deleteItem(url);
});
},
error: function (error) {
alert(JSON.stringify(error));
}
});
});
}
function deleteItem(url) {
$.ajax({
url: _spPageContextInfo.webAbsoluteUrl + url,
type: “DELETE”,
headers: {
“accept”: “application/json;odata=verbose”,
“X-RequestDigest”: $(“#__REQUESTDIGEST”).val(),
“If-Match”: “*”
},
success: function (data) {
},
error: function (error) {
alert(JSON.stringify(error));
}
});
}
</script>
Once you save the page and click on the button, it will delete all items from the Announcements list.
Hope this will be helpful.
