  • Sync from account creation date - transaction history must cover the full period from when you opened your HollaEx account with no gaps.

Frequently asked questions

Read Only permissions only. This gives KoinX access to your full transaction history without the ability to place trades or move funds. Never generate an API key with broader permissions for a third-party service.

​
Troubleshooting

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