how can I automate downloading an invoice's pdf?

AI generated answer (using internal Slack threads):

To automate the downloading of an invoice's PDF, you can use SuiteScript or SuiteTalk API in NetSuite. For SuiteScript, you can create a Map-Reduce script to load a search of all the invoices you want to print. The script will generate all the PDFs and set them into a NetSuite folder. Here is a general idea of how the script would look like:

javascript
/**
 * @NApiVersion 2.x
 * @NScriptType MapReduceScript
 */
define(['N/search', 'N/render', 'N/file', 'N/record'], function(search, render, file, record) {
    function getInputData() {
        // Load a search of all the invoices you want to print
    }
    function map(context) {
        // Generate the PDF for each invoice
    }
    function reduce(context) {
        // Save the PDF in a NetSuite folder
    }
    return {
        getInputData: getInputData,
        map: map,
        reduce: reduce
    };
});

For SuiteTalk, the closest solution is working with the File from SOAP web services. However, the PDF will have to already exist in this case. If you want to send an email from NetSuite and then attach the PDF invoice, you can add two states in a workflow. The first state adds an email invoice button. Use the email invoice button to transition to the second state and set action email. In the email body, write what you want to write and attach the PDF. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
