600+ credits consumed automating 3rd-party platform with broken API - requesting partial refund

Background

Used QoderWork to automate mandatory course completion on Guangdong Province Cadre Training Network Academy (gbpx.gd.gov.cn). Purchased 1019 add-on credits for this task.

Problem

603 credits were consumed during the automation process, but the target platform’s finished API returns a server-side configuration error (HTTP 500) for ALL requests regardless of parameters. This means courses cannot be marked as complete, making the task impossible to finish.

Root Cause

  1. Multiple sessions required due to complex platform anti-automation mechanisms
  2. Extensive API endpoint exploration (dozens of combinations) all failed
  3. Target platform server-side bug prevents course completion
  4. heartbeat API also broke with the same error later

Evidence

  • finished API returns status 500 for any parameter combination including no token
  • Server identifier: wlxy/52.17.3
  • Only 3 of 36 courses completed via progress threshold auto-complete mechanism not via API
  • Confirmed on 2026-05-30

Request

Since the task failure is due to the third-party platform API bug not a QoderWork issue, but significant credits were still consumed, requesting consideration for a partial credit refund.

Thank you!
