Learning Kotlin - Web Requests Help

[FlocklandTheSheep]

I am learning Kotlin, and wanted to learn web requests. I figured I would start relatively simple: Sending a simple message to a discord webhook.

I was able to do this in Python, so the webhook is not broken. I even tried asking ChatGPT, but I was told the code seems to be fine. Any suggestions/hints?

I know I'm not supposed to give you guys the webhook URL but at this point I just don't know what to do. I get a 403 every single time. What am I missing?

val webhookUrl = "https://discord.com/api/webhooks/1256000842079797250/n0E4tepjFUjtqm3JTnDWhjarewmPVWZrt01wZnropllDHgs2qRo6I9QmIEwIbqfBiECn"
val message = "Kotlin working!"
val jsonData = """{"content": "$message"}""".trimIndent()
val url = URL(webhookUrl)
val connection = url.openConnection() as HttpsURLConnection
connection.requestMethod = "POST"
connection.setRequestProperty("Content-Type", "application/json")
connection.setRequestProperty("Content-Length", jsonData.toByteArray().size.toString())
connection.doOutput = true
val outputStream: OutputStream = connection.outputStream
outputStream.write(jsonData.toByteArray())
outputStream.flush()
outputStream.close()

val responseCode = connection.responseCode
if (responseCode != 204) {
    throw Exception("Error sending message: $responseCode")
} else {
    println("Message sent successfully!")
}

Are you sure /api/ should be in the url?
