How to Create an api for the multiple attachment

rohit_hatkar1 · ‎09-28-2026

Hello Experts,

I need an api from the ServiceNow to add the multiple attachments to the incident record

I checked in the Api explorer but no luck.

ServiceNow OOTB Attachment API doesn't support multiple files

You can create Scripted REST API and ask 3rd party to send array of JSON object and then handle it using customization.

Hi @Ankur Bawiskar ,

Thank you for the response. I am trying to create the attachment using the AttachmentCreator in the ecc queu. Using the below code create an attachment but the problem is for docs and excel it is not working.

var parentTable = '<table_name>';
var parentRecord = '<table_sys_id>';

var ecc = new GlideRecord('ecc_queue');
ecc.agent = 'AttachmentCreator';
ecc.topic = 'AttachmentCreator';
ecc.source = parentTable + ':' + parentRecord;
ecc.name = '<file_name>:<mime_type>';
ecc.payload = '<base_64_encoded_file_content>';
ecc.insert();
