Any withdrawal request coming from an IP not on the whitelist will be automatically blocked. You can add up to **7 IP addresses** from your dashboard. This feature is recommended for: - Production servers - Preventing unauthorized withdrawal attempts ### How it works - Enable IP whitelisting from your dashboard - Add up to 7 trusted IP addresses - Only requests from those IPs will be allowed to initiate withdrawals If IP whitelisting is disabled, withdrawals can be initiated from any IP address. - name: Banks description: List, validate, add, and remove bank accounts for fiat withdrawals. - name: Transactions description: Retrieve deposit and trade transaction history. - name: Webhooks description: >- Inspect and retry **outgoing** webhooks we send to your server (trade and withdrawal events).
