API key notes

  • Read Only is required - keys with broader permissions may be rejected by KoinX as a security measure.
  • 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 BW 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.
No. BW displays the Secret Key only once at the time of creation. Copy it immediately and store it securely. If lost, delete the key from API Integration in your profile and generate a new one.
Yes. If you have a BW account and use it for crypto transactions and generating profits, you must file taxes. Follow the tax regulations set by the relevant authority in your region.
No. BW does not provide tax-ready reports. By connecting your BW account to KoinX via API key, your full transaction history is imported automatically and a compliant, country-specific tax report is generated within minutes.
Yes. KoinX supports 100+ countries with dedicated report formats for India, the US, UK, Australia, Canada, Germany, and more. After importing your BW data, select your country to generate the correct report.

​
Troubleshooting

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