What differs for JSON API

For quotes delivered as DOCX, templates are built in Word (3) and a visual builder (1). All 4 read JSON sent to an API without a Zapier, Make or n8n step in between. Of these, 1 has a free tier.

Besides DOCX, these tools for quotes also write PDF (4), e-sign documents (3) and XLSX (2). Your own code decides when to call the API, so a document can be built on any event. Prices were checked on 20 Oct 2026.
