Hi,
I'm working on an Docusign integration using the embedded flow and one of the requirements is after the user signs the document we capture the timestamp of the signature. After reading some of the docs and going through the code samples, there's still something not really making sense to me. How can I fetch the signing metadata after the user is redirected back to my application? I ran the code sample but the only parameter I get is a `signing_complete` event in the query string. I was expecting to get an "envelopeId" as one of the query string parameters so that I could use this parameter to issue a request to the EnvelopeRecipients:list endpoint.
