is there a way, using the Netsuite REST api, to automate adding a custom file attachment to be sent with the invoice to a client?

AI generated answer (using internal Slack threads):

Based on the conversations, it seems that it is possible to automate adding a custom file attachment to be sent with the invoice to a client using the NetSuite REST API. Here's a general approach based on the discussions: 1. First, you would need to POST the custom file (PDF, for example) to the RESTlet. The RESTlet would then save this file to the file cabinet in NetSuite. 2. Once the file is saved in the file cabinet, you can then attach it to the invoice record. This can be done using the

record.attach

operation as mentioned in the conversations. 3. It's important to note that the file data needs to be base64 encoded and placed somewhere in the JSON request body when sending to the RESTlet. 4. As for sending the invoice with the attached file to the client, you would need to use the appropriate operation in the REST API. This could be a PUT or POST operation depending on your specific use case. Please note that this is a general approach and the exact implementation may vary based on your specific requirements and the structure of your NetSuite environment. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
