I want to move my library from Mendeley to Zotero. First, I export the library in the *.bib format. The *.bib file contains the reference message and the path of attachment file. Second, I import the library from *.bib file. The reference message is import, but the attachment file have not been attached by Zotero. I want to code a javascript or python program to call the API and adding the attachment file to the item. However, Zotero only support the API to open the attachment. Can you tell me other method? In the next version, will Zotero support a API to add attachment?
