Post the Api Documentation on how the request must be done. I can not guess it!

I can not see any documentation on this site.

My data string looks like

{"exchange_data":[{"exchange_currency":"USD","exchange_rate_buy":"1505","exchange_rate_sell":"1512"},{"exchange_currency":"EUR","exchange_rate_buy":"1680","exchange_rate_sell":"1695"},{"exchange_currency":"SGD","exchange_rate_buy":"1095","exchange_rate_sell":"1111"},{"exchange_currency":"THB","exchange_rate_buy":"47.50","exchange_rate_sell":"49"}],"exchange_time":"18.07.2019"}}

and i coded like

 Dim parser As JSONParser
    parser.Initialize("parser")
    Dim root As Map = parser.NextObject
    Dim exchange_time As String = root.Get("exchange_time")
    Dim exchange_data As List = root.Get("exchange_data")
    For Each colexchange_data As Map In exchange_data
        Dim exchange_rate_buy As String = colexchange_data.Get("exchange_rate_buy")
        Dim exchange_rate_sell As String = colexchange_data.Get("exchange_rate_sell")
        Dim exchange_currency As String = colexchange_data.Get("exchange_currency")
    Next

   Log(exchange_rate_buy)
   Log(exchange_rate_sell)
   Log(exchange_currency)
   Log(exchange_time)

And i get this error

[DonManfred]

parser.Initialize("parser")

you are parsing the string "parser", not the json!
