LongPort API Error Codes

Authentication Errors

Code Meaning Fix
401004 Token invalid Token truncated/expired. Check bashrc has full token (1053 chars). Use Python to parse bashrc directly, don't rely on source.
403201 Auth failed Similar to 401004 — token masking by terminal tool. Use execute_code + SDK instead of CLI.

Geo-Restriction Errors

Code Meaning Fix
602315 Mainland China regulatory block API detects mainland China IP. Must use VPN (HK/US/etc). Read-only may still work; trading is blocked.

Trading Errors

Code Meaning Fix
301607 Too many k-lines requested Max ~1000 per candlesticks() call. Use history_candlesticks_by_offset() for pagination.

Common Error Patterns

  • 401004 + 602315: Both appeared in same session. 401004 was from truncated token in .env, 602315 after token was fixed (real token loaded from bashrc).
  • Token "..." truncation: bashrc shows m_eyJh...jb-k in grep output even when full 1053-char token exists. The ... is just display truncation by the shell/terminal, not in the actual file. Use python3 -c "import os; ..." to verify real length.
