Delete All List Items Sharepoint 2013 REST

Question

I need to delete all the Items in a Sharepoint List using REST API.
How can I achieve this?
I can delete a single Item using: "/_api/web/lists/getByTitle('MyList')/items('ID')"

I tried to remove the ID but it did not work.

You can try this

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));
    }
});
}

$.ajax({
    url: _spPageContextInfo.webAbsoluteUrl + "/_api/web/lists/getByTitle('MyList')/items",
    type: "GET",
    headers: {
        "accept": "application/json;odata=verbose",
    },
    success: function (data) {
        var items = data.d.results;
        for(var item in items){
            var url = "/_api/Web/Lists/getByTitle('MyList')/getItemById(item.ID)"
            deleteItem(url);
        }
    },
    error: function (error) {
        alert(JSON.stringify(error));
    }
});

You have to make one delete call for each item in the list, using a URI like you showed above, passing in each ID in succession. If there are LOTS of items in the list, it would likely be cheaper and faster to delete then recreate the list itself.
