packages

I am trying to update the text field inside a document in my draft package via post and/or put api for updating the specified document. The response is coming 200 on sanbox but wheneve I tried to change the value of the text field, it is not changing at all. 

 

How can we populate the value from database and use it in the text field area ? Our main requirement is to fetch the data from database and use this value to prepopulate in the text field section ? I have tried these two endpoint but it is not working. 

I'm having trouble sending a PDF with text tags to the /api/packages endpoint. My PDF is sent as base-64 encoded, and that string is "pasted" into a document when it reaches my eSignLive account. I'd like for the string to be decoded, so that the new package contains a copy of my original PDF.

If I update an existing package to SENT am I able to add any new documents to the package? Can I can update the package status to ACTIVE or some other status, add the document and then update status again to SENT?
