​
API key notes

  • Read Only is required - keys with broader permissions may be rejected by KoinX as a security measure.
  • Sync from account creation date - transaction history must cover the full period from when you opened your IDEX account with no gaps.
  • Review transactions after import - KoinX auto-classifies all transactions but a quick review helps catch any discrepancies before generating your report.

​
Frequently asked questions

​
Troubleshooting

Confirm Read Only is selected under API Restrictions in IDEX -> API Keys -> API Integration. Delete the credentials in KoinX and re-enter the key carefully - copy directly from IDEX to avoid invisible characters.
Ensure the transaction history covers the full period from your IDEX account creation date with no gaps. Trigger a manual re-sync from KoinX -> Integrations -> IDEX. If records are still missing, disconnect and reconnect with a fresh API key.
Check the IDEX platform for ongoing maintenance. If the platform is operational, verify the key is still active under API Keys. Regenerate if expired, re-enter credentials in KoinX, and trigger a fresh sync.
IDEX API keys can become inactive following account security changes. Log in to IDEX, check the key status under API Keys, and regenerate if inactive. Update the new credentials in KoinX under Integrations -> IDEX -> Edit.
Delete the existing IDEX integration from KoinX -> Integrations, reconnect with a fresh API key, and confirm the sync start date covers your full IDEX account history from the day it was created.
Check KoinX -> Integrations for duplicate IDEX connections and remove any extras. If a file was previously uploaded for the same period, delete those transactions before re-syncing via API.
