### Step 5: Configuring API Key Parameters

* You can create up to 251 keys per account;

If necessary, check the **"Maker Only"** box to limit the key to maker orders only.

### Step 7. Saving generated keys

After successful generation, you will see a window with your API keys:

* **API Key Index** - your key index;
* **Public Key** - your public key;
* **Private Key** - your private key.

> <mark style="color:$danger;">**⚠️CRITICALLY IMPORTANT:**</mark>

> * <mark style="color:red;">**The Private Key is displayed ONLY ONCE!;**</mark>
> * Be sure to copy and save your private key in a safe place;
> * Use the copy icons to the right of each field;
> * After closing this window, your private key will no longer be accessible;
> * If you lose your Private Key, you will have to generate a new API key.

Copy all three values: **API Key Index, Public Key, and Private Key.**
