Step-by-Step: Binance -> 3Commas Connection

Open Binance -> API Management.

Create a new key (label it "3commas-main").

Set permissions:

- Enable Reading = ON

- Enable Spot & Margin Trading = ON

- Enable Futures = ON (only if you actually use futures bots)

- Enable Withdrawals = OFF

Copy API Key + Secret once and store securely.

In 3Commas, go to My Exchanges -> Connect Exchange -> Binance.

Paste key + secret, select account type, and save.

Run a small paper/live test with minimum size.

Most Common Errors and Fixes

1) API-key format invalid

Use the new key generated after enabling security verification. Old copied keys often include hidden spaces.

2) Invalid API-key, IP, or permissions

Your trading permission is OFF or IP restriction does not match your current endpoint.

3) Timestamp for this request is outside recvWindow

System clock drift. Sync OS time and retry.

4) Futures bot cannot place orders

You enabled spot only. Turn ON futures permission on Binance and reconnect key in 3Commas.

• Pair: BTC/USDT
• Mode: DCA, spot only
• Max active deals: 1

• Safety orders: 4

Start small for 7 days, then scale if execution quality is stable.

FAQ

Is Binance + 3Commas safe?

Safer when withdrawals are disabled and keys are isolated per bot strategy.

Should I use one key for everything?

No. Separate keys reduce blast radius if one setup breaks.

Can I connect sub-accounts?

Yes, and it is often cleaner for separating spot vs futures automation.
