Populate a fillable PDF from XML data and a stored mapping template.

Overview

Populate a fillable PDF from XML data and a stored mapping template. Document formats have different failure modes. Confirm whether the workflow transforms data, fills an existing form, packages OpenXML, or only converts a file.

Key points

• Submit XML and identify the template by name or UUID.
• FeraRender runs the mapping XSLT.
• The PDF renderer fills the embedded form.
• Request application/pdf for binary output or JSON for base64 output.
• Unsupported content types return 406.

Recommended procedure

1. Choose the exact PDF or DOCX workflow.
2. Validate the source template or file.
3. Submit representative data with the expected response mode.
4. Open the resulting file and verify layout, fonts, fields, and metadata.

Troubleshooting

The PDF is blank or malformed

Validate the transform output or field mapping before blaming the conversion engine.

Fonts or pagination differ

Install required fonts and test with the same conversion engine used in production.

Conversion fails for one file

Open and resave the source DOCX, remove unsupported content, and compare it with a known-good file.
