Market Keys
How to add, secure, and manage the exchange API keys that power your algorithms
Market Keys
A market key is the API credential connection between Finterion and your exchange or broker account. Finterion uses it to read balances and place trades on your behalf — your funds always stay on the exchange itself.
Where to find your market keys
Open Dashboard → Markets to see every exchange or broker you've connected, along with its connection status and how many portfolios currently use it.
Adding a market key
- From Dashboard → Markets, select Add exchange.
- Choose the exchange or broker you want to connect.
- Give the connection a name (for example, "Main Binance account") so you can tell it apart from other connections later.
- Enter the credentials your exchange gives you:
- Most exchanges: API Key and Secret Key.
- Coinbase: an API Key Name and EC Private Key (Coinbase Developer Platform credentials).
- Select Verify Connection (or Test connection) — Finterion checks the credentials against the exchange before saving anything.
- Once verification succeeds, select Connect Exchange to save the market key.
Setting up your API key correctly
Before you generate the API key on your exchange, keep two things in mind:
- Grant the right permissions. Enable read and trade access. Leave withdrawal permissions off — Finterion never needs them and never touches your funds directly.
- Don't restrict by IP address. If your exchange offers IP whitelisting, leave it off. Finterion doesn't connect from a single fixed IP, so whitelisting a specific range will block the connection instead of protecting it.
Using a market key
Once a market key is connected, assign it when you create or connect a portfolio so your algorithms know which account to trade through. A single market key can back multiple portfolios.
Managing existing market keys
From Dashboard → Markets you can:
- Disconnect portfolios — stop the portfolios currently linked to a market key without deleting the key itself.
- Delete — permanently remove the market key. This requires typing the connection's name to confirm, since any portfolios still using it will stop trading through it.
