create invoice in draft status (requiring approval) through rest api

AI generated answer (using internal Slack threads):

To create an invoice in draft status (requiring approval) through REST API in NetSuite, you would need to set the invoice status to 'Pending Approval' during the creation process. However, it's important to note that the REST API might not support this functionality yet as it is still in BETA for many features. If you are using workflows, you can create a customer invoice approval workflow. Make sure to turn on the approval routing in Accounting Preferences. Upon creation, assign someone/role/group as approver to the button. Also, try selecting the workflow state where the invoices are pending approval in the Action filter. For previewing an invoice before it's sent to the customer, if you have the invoice default to pending approval, it will wait until approved to send. This way, you can preview the invoice (see the PDF) before it's sent out. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
