How can i expose the NetSuite customer invoice pdf to external applications from the transaction

AI generated answer (using internal Slack threads):

To expose the NetSuite customer invoice PDF to external applications from the transaction, you can use SuiteScript to generate a URL for the PDF file of the invoice. This URL can then be used by external applications to access the PDF. Here's a sample SuiteScript code that generates a URL for a PDF file of an invoice:

javascript
var file = nlapiPrintRecord('TRANSACTION', invoiceId, 'PDF', null);
var url = nlapiResolveURL('SUITELET', 'customscript_my_suitelet', 'customdeploy_my_suitelet');
url += '&fileid=' + file.getId();

In this code,

nlapiPrintRecord

is used to generate a PDF file of the invoice, and

nlapiResolveURL

is used to generate a URL for the Suitelet that will serve the PDF file. The ID of the PDF file is appended to the URL as a parameter. The Suitelet would then use the

nlapiLoadFile

function to load the PDF file and serve it as a response:

javascript
var fileId = request.getParameter('fileid');
var file = nlapiLoadFile(fileId);
response.setContentType('PDF', 'invoice.pdf', 'inline');
response.write(file.getValue());

In this code,

request.getParameter

is used to get the ID of the PDF file from the URL parameter,

nlapiLoadFile

is used to load the PDF file, and

response.write

is used to serve the PDF file as a response.
