    Issue: Webull Paper Trading Not Available via API

Status: Open
Date: 2026-04-16

Current State

Official OpenAPI SDK (webull-openapi-python-sdk): Auth works, account/balance/positions work, order placement works -- but it only sees the live account. No paper trading account exists in the API response, and the UAT endpoint rejects production keys.
