Broker APIs differ less on capability than on architecture, and the differences show up as work you have to do rather than boxes you cannot tick. A comparison of tastytrade and Public.com on the dimensions that actually change how you build.
TradingView cannot send an order to tastytrade. Something in the middle has to authenticate, translate, and submit — and the fifteen-minute session token, the legs array, and the eight-hour IP block all shape how that middle layer must be built.
Paper trading proves your software does what you told it to. That is genuinely valuable and a much smaller claim than it sounds. Knowing which questions a sandbox can answer is the difference between useful testing and false confidence.
The credential work takes minutes. Validating a configuration you should actually trade takes considerably longer, and treating setup as a minutes-long task is the mistake. Here is the full path, including what to verify at each stage and what to watch during the first live sessions.
Streaming replaces the polling loop, but tastytrade routes market data through dxFeed and that indirection creates traps. The wrong token endpoint can silently move you to delayed quotes, and option subscriptions need streamer symbols rather than trading symbols.
A procedural walkthrough for getting working tastytrade API credentials: OAuth application, scopes, personal grant, credential storage, and a verification pass that catches scope and refresh defects before they reach a live session.
The tastytrade order format is simple enough to get subtly wrong in ways that never throw an error. Per-unit pricing, the debit and credit sign convention, accepted versus filled, and what to do when a submission times out and you do not know whether it landed.
There is no published tastytrade requests-per-minute limit, which makes most advice on this topic invented. What is documented is more dangerous: an IP block for repeated failed logins, typically eight hours, delivered as a timeout rather than an error code. Here is how automated clients trigger it and how to build so they do not.
Session-token authentication is gone, but most tastytrade integration guides still teach it. Here is the current OAuth2 model, why the fifteen-minute session token is the easy part, how to avoid a refresh stampede under concurrency, and the specific failure modes that show up in production.
