Important Update: TD Ameritrade no longer exists as an independent broker following its acquisition by Charles Schwab. The TD Ameritrade API was discontinued as accounts migrated to Schwab, and Schwab has not yet released a replacement retail API as of 2025. This guide explains what happened to TD Ameritrade's API and explores alternative solutions for automated trading through platforms like TradersPost.

What Happened to TD Ameritrade's API?

The Schwab Acquisition

Charles Schwab completed its acquisition of TD Ameritrade in 2023, initiating a multi-year integration process. As part of this merger, TD Ameritrade accounts were migrated to Schwab's platform, and the TD Ameritrade API was permanently discontinued.

Current Status (2025)

  • TD Ameritrade API: No longer available
  • Schwab Retail API: Not yet launched despite earlier promises
  • thinkorswim Platform: Integrated into Schwab but without API access
  • Paper Trading: Available through thinkorswim's paperMoney simulator

What TD Ameritrade's API Previously Offered

Before its discontinuation, TD Ameritrade's API was one of the most comprehensive retail trading APIs, featuring:

  • Real-time and historical market data access
  • Equity and options trading capabilities
  • Account management and position tracking
  • Streaming data via WebSocket connections
  • Extensive documentation and developer support

Alternative Broker APIs for Automated Trading

With TD Ameritrade's API no longer available, traders need alternative solutions. Here are the major brokers currently offering official APIs for retail traders in 2025:

Interactive Brokers

  • Most Comprehensive API: Supports multiple programming languages

  • Tradier: Great for options-focused strategies
  • TradeStation: Good for futures and advanced order types

Important Considerations for 2025

Schwab's Future Plans

While Schwab has mentioned plans for developing a retail API, no concrete timeline has been provided as of 2025. Former TD Ameritrade API users should not wait for this uncertain development and should migrate to available alternatives.

Regulatory Compliance

When choosing an API provider, ensure they comply with:

  • SEC regulations for U.S. equities

  • Data protection and privacy laws

Cost Considerations

Compare the total costs including:

  • API access fees (if any)
  • Trading commissions
