POST /v1/pdf/form/fill

Use POST /v1/pdf/form/fields to inspect AcroForm fields, then POST /v1/pdf/form/fill to write values. Flatten is on by default so the result is a static PDF. This is not OCR.

Inspect with POST /v1/pdf/form/fields, then fill with POST /v1/pdf/form/fill. Flatten is on by default.

Example

Fill and flatten.
