Para recuperar os dados do pagamento, na activity de resposta, acesse a intent recebida. Então, use o parâmetro data da intent para obter a URI com as informações da transação.

val responseIntent = intent
if (Intent.ACTION_VIEW == responseIntent.action) {
   val uri = responseIntent.data
   val response = uri.getQueryParameter("response")
   val data = Base64.decode(response, Base64.DEFAULT)
   val json = String(data)
}

Assim que o pagamento é concluído, a Cielo Smart envia uma resposta para a URI configurada previamente. Essa resposta será um JSON contendo os dados da transação, seguindo o formato exemplificado abaixo:
