Doctavian is an enterprise-grade Intelligent Document Operating Platform, exposed as a headless REST API. Every capability — Document Generation and legally binding Digital Signatures — is available through a clean API interface. No UI dependency, no vendor lock-in, integrates with any stack.
Generate documents at scale — turn templates and data into pixel-perfect PDFs, DOCX, XLSX, and more, entirely server-side, synchronously or in batch.
Reuse with templates and pipelines — configure a Document Solution once and run it at any volume, no repeated setup.
Send for signature, programmatically — create envelopes, assign recipients, place fields, and track signing progress without touching a UI.
Track and audit everything — every action on every document and envelope is automatically recorded in a tamper-evident audit trail.
Get building: Stop reading and start building. Go to the Get Started section to grab our ready-to-run Postman collection, set up your credentials, and execute your first document generation or signing workflow in minutes.
Transform raw data into pixel-perfect PDFs, DOCX contracts, XLSX spreadsheets, PPTX presentations, or native Google formats — entirely server-side, at any scale. Define a template in the tools your team already uses, connect it to your data, and Doctavian handles the rendering.
Document Solutions — compose templates, data sources, and output settings into a named, reusable generation pipeline
Data Sources — configure GraphQL queries or pass embedded JSON to feed any generation request
Templates — author in Word, Excel, PowerPoint, Google Docs, Sheets, or Slides; enrich with elements and expressions
Programmatically manage the full signing lifecycle. Assemble documents, recipients, and signature fields into an envelope, send it, and track every action through to a tamper-evident audit trail — all via API.
Envelopes — group documents, recipients, and fields into a single signing transaction in one API call
Documents — upload documents, place signature fields with pixel precision across any page
Recipients — assign signer, viewer, and CC roles; configure sequential or parallel signing order; enforce MFA
Templates — save envelope configurations and instantiate new envelopes on demand
Audit Trail — tamper-evident log of every action, downloadable for compliance and legal purposes
