Choose your API path

Most solution pages are not separate endpoints. They map a workflow to one of the public gPdf APIs.

CUSTOM LAYOUT

JSON Render

Use POST /api/v1/pdf/render when your system controls pages, coordinates, elements, tables, barcodes, and settings.

REPEATED LAYOUT

Template Render

Use POST /api/v1/template-render when a published template owns the layout and callers only send business data.

EU E-INVOICE

E-Invoice Render

Use POST /api/v1/e-invoice/render for Factur-X / ZUGFeRD PDF/A-3b output with embedded EN 16931 CII XML.

Live solution pages

Each page states the endpoint to call, what gPdf handles, and what your system still owns.

    JSON to PDF API

    Convert structured application data into deterministic PDF documents without running a browser, shipping HTML/CSS, or storing customer files. Your system sends pages, elements, coordinates, settings, and business content; gPdf returns an application/pdf response.

    Batch PDF Generation API

    Render many PDFs from a queue or scheduled job by splitting work into safe requests, sending each document or template data item to gPdf, and storing or delivering the returned PDF in your own system.
