are Invoice and Customer note creation supported in the REST API?

AI generated answer (using internal Slack threads):

Based on the conversations provided, it appears that the creation of invoices is supported via the REST API in NetSuite. However, the REST API does not support the retrieval of invoice PDFs or the creation of customer notes. For the retrieval of invoice PDFs, you would need to use SuiteScript and the N/render to generate the PDF. You can then save it in the file cabinet to retrieve later, or write it to the response of a suitelet or restlet. However, please note that the REST API does not support file operations. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
