How can I verify TradingView JSON syntax before sending webhook alerts?

Question

Trader

When sending webhook payloads, my alerts fail on nested quotes and special characters. How can I validate the JSON before sending?

json

{
  "symbol": "{{ticker}}",
  "action": "{{strategy.order.action}}",
  "qty": {{strategy.order.contracts}}
}

Paste the message into any JSON validator after replacing the placeholders with sample values — TradingView only substitutes them when the alert fires.

Common mistakes:

Smart quotes (“ ”) copied from docs → use plain "
A trailing comma after the last field
Numeric placeholders like {{strategy.order.contracts}} must not be quoted

The JSON Bridge log in AlgoDelta shows the raw body it received, so you can compare.
