Failing to get Blynk notifications on the app. Asking for some help

Other Hardware Sensors

Trying to make a door sensor with a reed switch (usintg the D1 and GND pin) for my project, but no notifications show up. Asking for assistance. Below's my code:

#define BLYNK_TEMPLATE_ID "xxxxxxxxxxxx"
#define BLYNK_DEVICE_NAME "xxxxxxxxxxxxxxx"
#define BLYNK_AUTH_TOKEN "xxxxxxxxxxxxxxxxxxxxxxxxxxxxx"

#define BLYNK_PRINT Serial

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

char auth[] = BLYNK_AUTH_TOKEN;

char ssid[] = "xxxxxxxxxxx"; 
char pass[] = "xxxxxxxxxx"; 

BlynkTimer timer;

int flag=0;
int ReedSwitch = 1;

void notifyOnButton(){
  int isButtonPressed = digitalRead(ReedSwitch);
  if (isButtonPressed == HIGH) {
    Serial.println("Someone Opened the door");
    Blynk.notify("Alert : Someone Opened the door");
    flag=1;
  }
  else if (isButtonPressed == LOW)
  {
    flag=0;
  }
  }

void setup() {
  Serial.begin(9600);
  Blynk.begin(auth, ssid, pass);
  pinMode(ReedSwitch, INPUT_PULLUP);
  timer.setInterval(16000L, notifyOnButton); 
  
}

void loop() {
  Blynk.run();
  timer.run();
}

All those lines with xxxxxxxx in them. Are his not supposed to replace the string of xs with the real data for the device you are using?

Thanks for the help Mike :+1:t5:. yes they I've filled them with the required info ( template id, device name and template, auth token,, ssid and pass key respectively) but still does't work.
Help take me through how to get a Blynk alert notification when a reed switch sensor is opened connected to a generic ESP8266 chip. :pray:t5:

Sorry, I know very little about the ESP8266 processor.

Throw some more prints in there, particularly in notifyOnButton to verify that it gets called and what the state of the switch is.
