• Modular Approach: Designed for everything from personal projects to enterprise trading platforms, with a modular approach that allows you to integrate only the necessary components.

An API key is a unique code that lets you connect your app to the Firstock platform. It is required for:

• Authentication – So the system knows it's you.
• Access Control – It generates a token (jKey) that allows you to place orders, check account information, and more.

What You Need Before You Start

• You must have an active Firstock trading account.
• Make sure you can log in to the Key Generation Portal.
• Know where to find the API Key, Vendor Code, and other settings in your dashboard.

How to Generate Your API Key

Step 1: Go to the Key Generation Portal
Log in with your Firstock account credentials.

Step 2: Create Your API Key
Once you're logged in:

• Find the section called API Keys.
• Click Generate Key or Create New Key.
• Your AppKey and Vendor Code will be shown.

Make sure to copy and save them — you’ll need these for using the API.

Firstock API Login

Step 1: Go to the connect key generation and enter the firstock credentials

Step 2: Once logged in, you will find the appkey and vendor code. Please copy them and paste them into the fields in the login API.

Step 3: Upon a successful login, a status of success is returned along with a data object containing user-specific parameters.

Please keep in mind: The key expires after 365 days; a new one must be generated.

Step 4: In API Version 4 (V4), your password must be converted to SHA256 before sending it in the login request (only when using raw cURL or REST).

Step 5: If you're using the official Python package, the password encryption happens automatically.

Firstock API is a powerful tool for any serious trader or developer looking to automate strategies or build trading platforms. With REST + WebSocket support, real-time execution, SDKs, and detailed documentation, it delivers excellent value and flexibility.
