To import your Bybit transactions into CoinLedger, you'll need to create a System-Generated API Key with read-only permissions and no IP restriction.

First, navigate to API Management and click the Create New Key button. Select the correct Key Type, which is System-Generated API Keys, and keep the API Transaction option selected.

Give your key a name and select Read-Only under API Key Permissions. This ensures that read-only permissions are given to CoinLedger.

After clicking the Submit button, enter your 2FA code and click Confirm to create the keys. The API Secret is accessible only while this window is available, so be sure to store it somewhere safe.

To import your transactions, navigate to the CoinLedger import section and select the Bybit tab. Click on Auto-Import and enter your API Key and API Secret into the correct fields.

You can also specify a start date for your import to prevent duplicate data from being imported. However, if you're importing all your transactions for the first time, it's best to leave this field blank.

If you have subaccounts, create an API key for each of them and import them into CoinLedger one by one. The API keys created will automatically expire after 3 months, so be sure to create new ones before then.

Getting started with trading means understanding the basics, and one of the first things you'll need to do is get a list of active trading pairs.

This list includes both spot and derivatives trading pairs, which is essential for making informed decisions about your trades.

You can get this list by using the "Get Symbol List" function, which is a straightforward way to access the information you need.

The list will include all the active trading pairs, giving you a comprehensive view of the markets you can trade in.

The Bybit API offers a range of endpoints to manage your account and wallet, including viewing balances and wallet activity.

WebSocket for Real-Time Streaming is a game-changer for high-frequency trading and applications that require instant updates.

For applications that need real-time data, WebSocket is a better choice than REST. It allows you to subscribe to updates on order book changes, tickers, user trades, and wallet changes.

You can connect to the WebSocket stream using the following URLs: wss://stream.bybit.com/v5/public for public data and wss://stream.bybit.com/v5/private for private data.

Authentication over WebSocket requires a signed message using your API credentials.

To set up the API connection permissions, you'll need to navigate to the 'API permissions (check all that apply)' section. Select the 'Read-Write' option to begin.

Under the 'Contract' category, choose 'Orders' and 'Positions' to grant the necessary permissions. This will allow your API to manage and retrieve contract-related data.

To further refine the permissions, under the 'Spot' category, select 'Trade' to grant trading permissions. Once you've made your selections, click 'Submit' to finalize the API permissions.

Here are the specific permissions you'll need to set up:

To set the permissions for your API connection, proceed to the 'API permissions (check all that apply)' section and select the 'Read-Write' option. This will allow you to make changes to your API settings.

Rate limits are in place to prevent overloading of systems and ensure fair usage. Bybit applies per-endpoint rate limits.

These limits are designed to prevent unnecessary polling of high-frequency endpoints. Try not to poll high-frequency endpoints needlessly.

The X-RateLimit-Reset and Retry-After headers are used to manage throttling. You can use these headers to determine when you can retry a request.

WebSocket is a more efficient option for real-time data, and it can help reduce the need for polling. Use WebSocket where you can.

Error handling is crucial for a seamless experience. Bybit returns standard HTTP response codes, which is a good practice.

These codes are accompanied by a retCode inside the JSON body. For example, a retCode of 0 indicates success.

You should always verify the contents of responses, especially for fund transfers and order placements. This ensures that you're not acting on incorrect information.

Here are some common retCodes you may encounter:

A good integration should also handle timeouts and retries. This helps prevent errors from occurring in the first place.
