Hi John,

Did you mean to export / import PDF or the XFDF string? To export / import the XFDF with custom data you can just use the API annotationManager.exportAnnotations and API annotationManager.importAnnotations. You will find the custom data in the exported XFDF string on an attribute called “trn-custom-data”.

To export / import PDF you can just use APIUI.downloadPdf and documentViewer.loadDocument.
