Welcome!
We have released an update to support WebGL rendering with our HTML to PDF and URL to PDF API endpoints via Headless Chrome.
Please be mindful that you may need to the delay attribute since WebGL content often needs more time to render.
See details on the delay attribute here: https://www.api2pdf.com/resolved-pdf-is-rendering-blank-or-only-partially-with-headless-chrome
Also keep in mind that WebGL rendering requires more CPU and memory resources to generate a PDF. It may make sense to switch to using our v2-xl.api2pdf.com endpoints (at higher fees).
