Waltio connects to your exchange platforms via read-only API keys: we can only read your data and cannot perform any transfers or withdrawals. Public and secret keys are encrypted via a KMS (Key Management Services) system to secure your data.

Once an API connection is created, all your transactions since the creation of your account on the exchange will be read. Some APIs do not read all transactions — we inform you of this in the dedicated article for each platform.

Find tutorials for each platform we support via API in the dedicated article.

💡 If one of your APIs is not properly synchronized, you will not be able to generate a fiscal report. Check the relevant article if this happens.

Automatic synchronization

All your transactions are automatically updated every 7 days if you log in to Waltio, and every 3 months if you do not log in.

Transactions that took place on the same day as the synchronization are not valued in € (prices are not available from our data providers that day): the value will be automatically updated during the next analysis.

Files and API combined

If you have added files to your Waltio account containing transactions also read by API, Waltio will let you choose between:

FIAT ↔ Crypto trade

For a FIAT ↔ Crypto trade, we always calculate the price using the FIAT amount and the quantity traded to get the most accurate calculation possible.

Manually deleted transactions

If you delete transactions added via API, they will reappear at the next synchronization. A deleted transaction cannot be saved as deleted in our database.

It is possible to pause an API to block new synchronizations and avoid this behavior. Contact us at hello@waltio.com to make the request.

Full Sync

We can also run a "Full Sync" which resynchronizes all your transactions from the very first one. Contact us at hello@waltio.com.
