Pinescript alert variables

Question

I'm looking for a way to send an identification of a user in the message of a webhook. The user should be able to input their ID and it should be sent in the message when the webhook alert is triggered. So far I have not been able to use custom variables in the message and it seems this is not supported.

myID = input(title="myID", type=input.string, defval="1000")

//===============================
// Alert to trigger Buy
//===============================
alertcondition([YourAlertCondition], title = "Buy", message = "{\"side\": \"Buy\", \"symbol\": \"ASSETNAME\", \"type\": \"Market\", \"amount\": \"20\", \"takeProfit\": \"1\", \"stopLoss\": \"1\", \"trailingStop\": \"None\", \"new_trailing_active\": \"None\", \"Leverage\": \"1\", \"TelegramID\":"+{{myID}}}+"")

Expected Output:

{"side": "Sell", "symbol": "ASSETNAME", "type": "Market", "amount": "20", "takeProfit": "1", "stopLoss": "1", "trailingStop": "None", "new_trailing_active": "None", "Leverage": "1", "myID": "1000" }

The method above is what I have tried with some variations. If it's not possible to use a variable, is there a way to output the user's TradingView username in the message? If that's possible the TradingView username can be used as the ID on the receiving server.

You could use the alert function instead of alertcondition, in your case you could use:

msg = '{' + str.format('\"side\": \"Buy\", \"symbol\": \"ASSETNAME\", \"type\": \"Market\", \"amount\": \"20\", \"takeProfit\": \"1\", \"stopLoss\": \"1\", \"trailingStop\": \"None\", \"new_trailing_active\": \"None\", \"Leverage\": \"1\", \"TelegramID\":"{0}"',myID) + '}'

if YourAlertCondition
    alert(msg,alert.freq_once_per_bar_close)

see the refman on alert.
