How to receive String Data on your nodeMCU?

Am trying to receive data from a Maker Channel web request on IFTTT, but I cannot seem to figure out how to receive Strings as an option when I push values through the URL JSON call.

Below is the code am working on. Any help is appreciated.

What I want to do is receive information on IFTTT events, like “Tina clicked a new pic” and then display it on an LCD monitor or send data back to IFTTT and send out a SMS for example.

#define _DEBUG_
#include <ESP8266WiFi.h>
#include <ThingerWifi.h>

#define USERNAME "name"
#define DEVICE_ID "nodemcu"
#define DEVICE_CREDENTIAL "nodemcu"

#define SSID "SSID"
#define SSID_PASSWORD "password"

void setup() {
  thing.add_wifi(SSID, SSID_PASSWORD);

  thing["ifttt"] << [](pson& in) {
    String x = in["value1"];
    String y = in["value2"];


void loop() {

Hi! You should define the output type to const char*, as String is not defined in the standard C/C++ nor STL, so it cannot be used directly to translate from a pson value. Modify your resource definition to the following:

  thing["ifttt"] << [](pson& in) {
    const char* x = in["value1"];
    const char* y = in["value2"];

Hope that works!
