while compiling showing error - Expected Inititializer before Int

CAYENNE_IN , CAYENNE_IN(VIRTUAL_CHANNEL)
int value = getValue.asInt();
if (getValue.asInt() == 1) { // NOTE: Channel = Virtual Pin
digitalWrite(PUMP, LOW);
}
else {
digitalWrite(PUMP, HIGH);

you are missing many } in your code.

replace this in your code:

// Default function for sending sensor data at intervals to Cayenne.
// You can also use functions for specific channels, e.g CAYENNE_OUT(1) for sending channel 1 data.
CAYENNE_OUT_DEFAULT()
{

  long duration, distance;
  digitalWrite(TRIGGER, LOW);
  delayMicroseconds(2);

  digitalWrite(TRIGGER, HIGH);
  delayMicroseconds(10);

  digitalWrite(TRIGGER, LOW);
  duration = pulseIn(ECHO, HIGH);
  distance = (duration / 2) / 29.1;

  if (distance >= 150) 
  {
    Cayenne.virtualWrite(0, 255);
  }
  else 
  {
    Cayenne.virtualWrite(0, 0);
  }
  if (distance <= 15) 
  {
    digitalWrite(PUMP, LOW);
    Cayenne.virtualWrite(2, 0);
  }
  else 
  {
    if (distance >= 100) 
    {
      digitalWrite(PUMP, HIGH);
      Cayenne.virtualWrite(2, 255);
    } 
    else 
    {
      Serial.print(distance);
      Serial.println("Centimeter: ");
      Cayenne.virtualWrite(5, distance);
    }
  }
}

CAYENNE_IN(VIRTUAL_CHANNEL)
{
  int value = getValue.asInt();
  if (getValue.asInt() == 1) 
  { 
    digitalWrite(PUMP, LOW);
  }
  else 
  {
    digitalWrite(PUMP, HIGH);
  }
}
