/**************************************************************
 *
 * This sketch connects to a website and downloads a page.
 * It can be used to perform HTTP/RESTful API calls.
 *
 * For this example, you need to install ArduinoHttpClient library:
 *   https://github.com/arduino-libraries/ArduinoHttpClient
 *   or from http://librarymanager/all#ArduinoHttpClient
 *
 * TinyGSM Getting Started guide:
 *   https://tiny.cc/tinygsm-readme
 *
 * SSL/TLS is not yet supported on the Quectel modems
 * The A6/A7/A20 and M590 are not capable of SSL/TLS
 *
 * For more HTTP API examples, see ArduinoHttpClient library
 *
 * NOTE: This example may NOT work with the XBee because the
 * HttpClient library does not empty to serial buffer fast enough
 * and the buffer overflow causes the HttpClient library to stall.
 * Boards with faster processors may work, 8MHz boards will not.
