Common Error Codes and Solutions

1. Timestamp Request Expired (Error Code 30008)

Error Message:
{"error_message":"Request timestamp expired","code":30008,"error_code":"30008","message":"Request timestamp expired"}

Causes and Fixes:

Windows Systems:
The system clock may be out of sync with Beijing Time (OKEX's reference). Synchronize your system clock via Internet Time settings.
Linux Systems:
Ensure your server's timezone is correctly configured. For detailed steps, refer to 👉 Linux Server Timezone Configuration.

2. Missing API Credentials (Error Code 30001)

Error Message:
{"error_message":"OK-ACCESS-KEY header is required","code":30001,"error_code":"30001","message":"OK-ACCESS-KEY header is required"}

Example Request Headers:

Content-Type: application/json
OK-ACCESS-KEY: 37c541a1-****-****-****-10fe7a038418
OK-ACCESS-SIGN: leaVRETrtaoEQ3yI9qEtI1CZ82ikZ4xSG5Kj8gnl3uw=
OK-ACCESS-PASSPHRASE: 1****6
OK-ACCESS-TIMESTAMP: 2020-03-28T12:21:41.274Z

FAQ Section

Q1: Why does my API request keep failing with Error 30008?

A: This occurs when your system clock drifts from OKEX's timestamp validation window (usually ±30 seconds). Sync your clock or use NTP services.

Q2: How do I troubleshoot "Invalid Authority" errors?

A: Double-check API permissions in your OKEX account dashboard. Ensure you've selected all necessary access scopes.

Q3: What’s the quickest fix for timestamp issues on Linux?

A: Run sudo timedatectl set-ntp true to enable automatic time synchronization. For more details, see 👉 Time Sync Solutions.
