Unzip downloaded files

Hey Jack, If you download the documents individually, they don't come in a zip file. Are you downloading with the API or one of the SDKs or are you using the UI to download? To download with the REST API, you'd make a call like this:

HTTP Request
GET https://sandbox.esignlive.com/api/packages/{packageId}/documents/{documentId}/pdf

HTTP Headers
Accept: application/pdf
Content-Type: application/json
Authorization: Basic api_key

There are similar options with the SDK that you can see in the Document Retrieval guide. As for unzipping a zip file programmatically once you have downloaded the zip file on your end, of course you can do this. You can find a guide elsewhere on the internet for your programming language with a quick Google search. Hope this helps.
