How to Download Attachment from URL?

[testp21]

I have done a third party integration. They are sending a URL which, I store in a URL field. Now, how can I download and attach the file in existing record?

You can write an async/update BR and use the following script-

(function executeRule(current, previous /*null when async*/ ) {

    var endpointURL = current.u_url;
   var attachmentName = "Attachment Name" + current.number + ".mp4";

    var request = new sn_ws.RESTMessageV2();
    request.setHttpMethod('GET');
    request.setEndpoint(endpointURL);

    request.saveResponseBodyAsAttachment('Table Name', current.sys_id, attachmentName);

    var response = request.execute();

    if (response.getStatusCode() == 200) {
        // Get the response body (file content)
        var responseBody = response.getBody();
    } else {
        gs.error("Failed to retrieve file. HTTP Status Code: " + response.getStatusCode());
    }
})(current, previous);
