API key notes

  • Both Check Assets and Query Assets must be selected - missing either permission will result in incomplete transaction data being imported.
  • Secret Key is shown once only - copy it immediately at the time of creation and store it securely.
  • Sync from account creation date - transaction history must cover the full period from when you opened your BKEX account with no gaps.

​
Troubleshooting

Confirm both Check Assets and Query Assets are selected in BKEX -> Profile -> API Management. Delete the credentials in KoinX and re-enter both values carefully - copy directly from BKEX to avoid invisible characters.
Ensure the transaction history covers the full period from your BKEX account creation date with no gaps. Trigger a manual re-sync from KoinX -> Integrations -> BKEX. If records are still missing, confirm both permissions are selected on the key and reconnect with a fresh API key if needed.
Check the BKEX platform for ongoing maintenance. If the platform is operational, verify the key is still active under API Management. Regenerate if expired, re-enter credentials in KoinX, and trigger a fresh sync.
BKEX API keys can become inactive following account security changes. Log in to BKEX, check the key status under API Management, and regenerate if inactive. Update the new credentials in KoinX under Integrations -> BKEX -> Edit.
Confirm both Check Assets and Query Assets permissions are selected on the API key. If either is missing, delete the key from BKEX -> API Management, generate a new key with both permissions, and reconnect in KoinX.
Check KoinX -> Integrations for duplicate BKEX connections and remove any extras. If a file was previously uploaded for the same period, delete those transactions before re-syncing via API.
