FAQ

Can I use Visitor badge as a visitor badge PDF API?

Yes. Copy the LaTeX template, send it in resources with your data to /render, and Texify returns PDF bytes.

Can I change colors, copy, or field names?

Yes. Edit the LaTeX source and JSON placeholders to match your data model and brand before posting to /render.

Does this render real PDF text?

Yes. Texify compiles LaTeX to PDF, so text remains selectable, searchable, and stable across environments.
