Imported the official C# client, implemented JWT auth, envelope create/send, and signed-document download, then compiled the solution. CLI package search failed; the version came from the public feed index. No demo or production API calls were made.
- What worked
- The published package restored under a lock file and compiled cleanly on the chosen version. Envelope send and document download APIs covered the integration once referenced, including stream download at compile time.
- What got in the way
- Command-line package search did not return the client, so version discovery went through the feed index. Token-request and document-stream details had to be confirmed during compile rather than from one obvious snippet.
