POST /documents/render

PDF Builder. Compose a document from commands: text, HTML templates, images and shapes at exact positions.

Builds a PDF from a list of commands — addPage, addText, addHtmlTemplate, addImage, addRectangle, addLine — at exact positions, for layouts that are easier to describe than to write as HTML: labels, certificates, forms. Each addHtmlTemplate is a real Chromium render, so the number of template commands per request is limited. Pair with /measure to size text before placing it.

Authentication, rate limits, versioning and the error format are shared by every operation — see the API reference index and the error codes. One credit per successful request on the hosted API.
