Common API Errors When Automating TradingView — And How to Fix Them

Automating TradingView alerts via Webhooks is the gold standard for modern retail traders. However, technical “handshake” errors between the TradingView server and Indian broker APIs (like Zerodha Kite, Upstox, or Angel One) can lead to missed trades or failed execution. Below is a deep-dive guide to the most common errors handled by Jayadev Rana’s custom automation setups.

1. Webhook URL 404/500 Errors

This usually happens when your API bridge listener is down or the URL is incorrect. In professional setups, we use redundant cloud listeners to ensure that even if one server flickers, your trade alert is captured.

2. “Invalid Token” or Session Expiry

Indian brokers require a fresh access token every day (usually before 9:15 AM). If your automation isn’t refreshing this token automatically, the API will reject your TradingView alert. We build auto-login scripts that refresh sessions at 8:30 AM daily.

3. “429 Too Many Requests” (Rate Limiting)

If you are running a high-frequency scalping strategy, you might hit the broker’s API rate limit. We solve this by implementing “Request Queueing”—staggering the orders by milliseconds so they all go through without being blocked.
