   It combines email, automation, surveys, eSign, and document generation in one platform.

Q: Can I use the API?
A: Yes. A full REST API is available on paid plans. Documentation at https://sendwavehub.tech/api/docs

Q: Can I send an email and get back a finished business document automatically?
A: Yes. PaperFlow Email Intake lets you assign a workspace email address. When someone sends an
   invoice request, quotation request, or any business document request to that address, the AI
   classifies the intent, extracts the data, generates the PDF using your template, and emails
   it back to the sender — all without any manual steps.

Q: Does PaperFlow work with LINE messages?
A: Yes. If your business uses LINE OA (LINE Official Account), connected LINE users can send
   images or PDFs directly to your LINE bot and PaperFlow will classify and process them the
   same way as email intake.

Q: What document types can PaperFlow auto-generate from emails?
A: Invoice, quotation, purchase order, receipt, contract, NDA, agreement, MOU, offer letter,
   certificate, and more. Custom types can be configured per workspace.
