# invalid_action

> Signal webhook: the alert's action is not one Tickwire knows.

Source: https://tickwire.io/docs/errors/invalid_action/

HTTP 400. Nothing reached the broker.

**Likely causes:**

- A typo in action.
- A TradingView placeholder filled in a value that is not an action.

**What to do:** Use one of the actions listed in the message. See the [TradingView alerts guide](https://tickwire.io/docs/guides/tradingview-alerts/).

**Retry:** No. The same request gets the same answer; change something first.
