/*
 * 46elks samples: Sending a text message
 * ===
 *
 * This example introduces you with how to send a text message. The scenario is that
 * a text message is sent to a pre-defined phone number each time a specific endpoint,
 * in this case /send, is opened by someone, but the same basic principles can be applied
 * for all kinds of situations.
 *
 * Setup
 * ---
 *
 * Change the phone number that will receive the text message (see the listener() function).
 * Provide your own API username and API password (see the sendSms() function).
