# Getting API Keys for OKX

**Important:** when creating a key, the system will send a confirmation code to your phone and email.

### Main Account

1. Log in to your OKX account
2. Go to profile menu → "API" section
3. Click "Create API Key"

### Configuring Parameters

Fill in the following fields:

* **Name:** enter a meaningful name (for example, "MoonTrader")
* **Purpose:** Trade API
* **Permissions:** Read and Trade
* **Passphrase:** create a unique password for the key

### Configuring IP Whitelist (Recommended)

When creating API keys, it is recommended to specify a list of allowed IP addresses. Only devices with the specified IPs will be able to use the key — this protects against unauthorized access, even if an attacker obtains your keys.

**Which IPs to specify:**

* the public IP address of the server running the MoonTrader core
* the public IP address of the server with Watchdog monitoring system (if used)

**Configuration:**

1. In the "IP whitelist" field, add the static IP of your server
2. If using Watchdog on a separate server — also add its IP

### Confirmation and Saving

1. Confirm creation with codes from SMS and email
2. Save the **API Key, Secret, and Passphrase** — they are displayed only once

### Creating Keys for Subaccounts

1. Complete all key creation steps described above
2. In the "Account" field, select the required subaccount instead of the main account
3. Configure the key parameters similarly to the main account

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://guide.moontrader.com/en-moontrader-docs/getting-started/working-with-exchanges/getting-api-keys-for-trading/getting-api-keys-for-okx.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
