paymongo-kotlin-ktor-server verifies the Paymongo-Signature header, decodes the payload, and optionally flags redelivered events. See samples/server for a full runnable example.

implementation("io.github.ronjunevaldoz:paymongo-kotlin-ktor-server:<VERSION>")

routing {
    route("/webhooks/paymongo") {
        install(PayMongoWebhookVerification) {
            secretKey = "whsec_..."
            dedupStore = InMemoryPayMongoWebhookDedupStore() // opt-in; process-local only
        }
        post {
            if (call.isDuplicatePayMongoEvent) {
                call.respond(HttpStatusCode.OK)
                return@post
            }
            when (call.payMongoEvent.data.attributes.type) {
                WebhookEvent.Event.PaymentPaid -> { /* fulfill the order */ }
                else -> {}
            }
            call.respond(HttpStatusCode.OK)
        }
    }
}

A missing/malformed signature header throws PayMongoSignatureFormatException; a signature mismatch throws PayMongoSignatureMismatchException. Install Ktor's StatusPages to map either to a 400, or they surface as an unhandled 500.
