Delete Attachment From List Item in SharePoint using REST API

The example in this topic show how to use REST API to Delete Attachment From List Item in SharePoint

REST-API is based on OData (Open Data) Protocol and hence it doesn't require any dll or JS library to run the commands on the SharePoint objects.
REST-API calls require proper end-point URL and proper Header implementation in your REST call.

I have added below Html in Content Editor webpart. You can replace MainFunction with your actual method name.
<button onclick="MainFunction();" type="button">Click me</button>
And below references in Script Editor Webpart. ScriptFile.js is a JavaScript file where you can keep below function i.e. your actual logic.
<script src="https://MyServer/sites/SiteCollection/style library/js/ScriptFile.js"></script>
Once you are done with setting your page, click on the button and your method should get executed.

function DeleteListItemAttachment() {
// Specify the Id of the Item that you want to fetch
var Itemid = 1;
// Specify the Name of the document(attachment) that you want to delete
var ItemAttachmentName = 'Document.docx';
$.ajax
({
// _spPageContextInfo.webAbsoluteUrl - will give absolute URL of the site where you are running the code.
// You can replace this with other site URL where you want to apply the function
url: _spPageContextInfo.webAbsoluteUrl + "/_api/web/lists/getByTitle('List Name')/items(" + Itemid + ")/AttachmentFiles('"+ ItemAttachmentName +"')",
method: "DELETE",
headers:
{
// X-RequestDigest header: When you send a POST request, it must include the form digest value in X-RequestDigest header
"X-RequestDigest": $('#__REQUESTDIGEST').val(),
"X-HTTP-Method": "DELETE",
// Accept header: Specifies the format for response data from the server.
"Accept": "application/json;odata=verbose"
},
success: function (data, status, xhr) {
console.log('Item attachment deleted ');
},
error: function (xhr, status, error) {
console.log("Failed");
}
});
}
