Injecting fields

Hello,

I am trying to inject data into a field on a PDF that is uploaded to onespan. I have the field in the following format

[Signer1.Capture1.Textfield1]

 

the REST API to inject says to use the field names, but the tagging syntax doesn't allow for a name to be added based on the PDF field template found below. do i just put "Textfield1" as the name in the fields section of the documents when sending the package?

https://community.onespan.com/documentation/onespan-sign/guides/feature-guides/developer/document-extraction

Any help would be much appreciated.

if you have a PDF with tagged fields that would work in this case, please attach it as well! :)

Thanks,

Matt
