Get time with API in Arduino

I'm trying to get the current local time with an API. I am using a WEMOS D1 Mini and the get method with blynk to return JSON from the API and store it.

I use this code

#define BLYNK_PRINT Serial

#include <ESP8266WiFi.h>
#include <ArduinoJson.h>
#include <BlynkSimpleEsp8266.h>

String json;
char auth[] = "";
char ssid[] = "YourNetworkName";
char pass[] = "YourPassword";

BLYNK_WRITE(V0) {
  json = param.asStr();
}

void setup() {
  Serial.begin(9600);
  Blynk.begin(auth, ssid, pass);
}

void loop() {
  Blynk.run();
  Blynk.virtualWrite(V0, "https://api.bot-dev.org/time/");
  JsonObject& root = jsonBuffer.parseObject(json);
  long time = root[String("ENtime")];
}

But i cant receive time in long time variable.

You can do that in simpler way. You need to add WebHook widget to your app. In the webhoook widget you need to put https://api.bot-dev.org/time/ url. And assign this widget to the virtual pin, let's say V0. Webhook widget will return response to your hardware after it was triggered. So your code should look like that:

BLYNK_WRITE(V0) {
  //here you'll get response from the webhook
  json = param.asStr();
}

void setup() {
  Serial.begin(9600);
  Blynk.begin(auth, ssid, pass);
}

void loop() {
  Blynk.run();

  //trigger the webhook
  Blynk.virtualWrite(V0, 1); //you can send any value to trigger webhook
}

Have in mind that you need also to move out Blynk.virtualWrite from main loop in order to avoid flooding.

Here is more details regarding the webhook widget.
