How to convert attachment to Base64 format?

Hi Community,

I am working on an integration where the 3rd party system requires ServiceNow attachments to be sent in Base64 format.
How to achieve this?

Regards,
Ritik

Hi @nirwan_ritik ,

Check below code

var gsa = new GlideSysAttachment();
var attachmentSysId = "attachment_sys_id"; 
var fileBytes = gsa.getBytes(attachmentSysId);
var base64Encoded = GlideStringUtil.base64Encode(fileBytes);
gs.info("Base64 Encoded String: " + base64Encoded);

Hi @nirwan_ritik ,

Hope you are doing good!!

Please review the below code- 

var table = 'incident';  // or your table name
var recordSysId = 'abc123...';  // sys_id of the record
var fileName = 'example.pdf';  // name of the attachment file

var attachment = new GlideSysAttachment();
var fileBytes = attachment.getBytes(table, recordSysId, fileName);

// Convert to Base64
var base64 = Packages.java.util.Base64.getEncoder().encodeToString(fileBytes);

// Log or use the Base64 string
gs.info("Base64 content: " + base64);
