Frequently Asked Questions
What can I do with API access?
Traders can build and run trading bots, connect scripts or automation from platforms like TradingView, create custom dashboards and tools, set up trade alerts and monitoring systems, copy trades across accounts, and automate order execution based on their strategies.
What programming languages can I use?
The REST API is compatible with most modern languages, including Python, Java, .NET, JavaScript, and more. Anything that can call a RESTful API or use WebSocket connections will work.
How do I get started?
You can subscribe through the ProjectX Login Page. Once subscribed, you’ll receive access to developer docs, authentication instructions, and integration guides.
Is there a sandbox environment for testing?
No, there is currently no sandbox environment available.
Can I access TradingView’s APIs through this?
No. This API does not include TradingView’s proprietary charting APIs or visualization tools.
What’s included with the subscription?
Your API subscription includes your API token, access to REST and WebSocket APIs, real-time market data, integration tools, developer documentation, dashboard management tools, and access to ProjectX's help resources and support routing.

How do I authenticate?
You’ll generate an API key inside your ProjectX settings. Use this key to authenticate your requests through OAuth.
Do I need to know how to code?
If you're building your own tools, some coding knowledge is required. However, you don’t need to code if you’re using third-party tools built by others—just plug in your credentials.
Is this a free feature?
No. API access is a paid monthly subscription. Pricing is TBD and will include access to the API and real-time market data.
Who do I contact for support?
For basic access and onboarding, contact the Topstep support team. If needed, support will be escalated to ProjectX for payment issues, technical integration, and troubleshooting.
How much does it cost?
API Access is $29/month. But Topstep Traders have access to a code for 50% off the duration of the subscription.
What is the code and what are the details?
Use code topstep when purchasing your API Access subscription. This code is for 50% off the monthly price, every month, for the duration of the subscription. This will make your month cost $14.50/month. There is no end date for the code.
