What Is the Document Generation API?
A cloud-based engine that connects your CRM, ERP, or line-of-business system to your templates hosted in Papertrail.
You send structured data → we return a fully generated document – or deliver it straight to your customer.
Think of it as your team’s centralized, compliant document factory.
Create, Send and Store your Letters Directly from your CRM
Automate the creation of contracts, letters, agreements, onboarding packs, and customer notifications directly from your CRM or business system.
Papertrail’s Document Generation API merges your data with your stored templates and delivers the completed document by Email, SMS, or WhatsApp—instantly and at scale.

How it Works:
1. Store Templates in Papertrail
Upload your DOCX, PDF, or HTML templates. Add dynamic fields, conditions, and branding.
2. Send Data via API
Your CRM sends a JSON payload with customer or transaction fields.
3. Document Auto-Generated
Papertrail merges data with your chosen template and produces a final PDF or DOCX.
4. Deliver or Return
Send via Email/SMS/WhatsApp or receive the file back via API. Delivery logs included.
