Get attachments from Third party to ServiceNow using Rest API

[Ashok32]

Hi All,

I have a requirement to get all the attachments which are attached by the Third party in their tool and update the same attachments in the incident record in ServiceNow.

For that I use Get method and I'm passing the below details are the Request headers.

Content-Type =<which specifies the content type of a file>

X-MessageType = file

X-FileName =<specifies the file name that they are attched from their end>

X-MessageId =<ID which they passed as unique>

X-EntityType= incident

X-Action = update

X-Integration =<they provided the details>

So can someone help me the script to achieve this requirement.

Thanks in advance.

HI @Ashok32 ,
I trust you are doing great.

Below is a basic outline of the script you can use in ServiceNow.

// Define the endpoint of the third-party service
var thirdPartyEndpoint = 'https://third-party-service/endpoint';

// Set up the request headers
var headers = {
    'Content-Type': '<content-type>',
    'X-MessageType': 'file',
    'X-FileName': '<file-name>',
    'X-MessageId': '<message-id>',
    'X-EntityType': 'incident',
    'X-Action': 'update',
    'X-Integration': '<integration-details>'
};

// Function to fetch attachments from the third-party tool
function fetchAttachments() {
    var client = new sn_ws.RESTMessageV2();
    client.setEndpoint(thirdPartyEndpoint);
    client.setHttpMethod('GET');

    // Add headers to the request
    Object.keys(headers).forEach(function(key) {
        client.setRequestHeader(key, headers[key]);
    });

    // Send the request and get the response
    var response = client.execute();
    var responseBody = response.getBody();
    var httpStatus = response.getStatusCode();

    if (httpStatus == 200) {
        // Process and upload attachments to ServiceNow
        uploadAttachmentsToServiceNow(responseBody);
    } else {
        // Handle errors
        gs.error('Error fetching attachments: ' + httpStatus);
    }
}

// Function to upload attachments to a ServiceNow incident
function uploadAttachmentsToServiceNow(attachments) {
    // Assume 'attachments' is the parsed data from the third-party tool
    // Loop through each attachment and upload it to the ServiceNow incident

    // For demonstration,
