My website doesn't receive data from webhook

Hey, I created webhook to send temperature data, in event panel it shows that hook has been sent, but my website doesn’t receive anything.

And there’s also weird response from Webhook in internal-terminal even if its not called!

Here’s my particle Code

#include "IRremoteLearn.h"
#include "math.h"

const int SEND_PIN = TX;
int ky013Pin = D3; // Digital I/O pin connected to KY-013 OUT pin
float thermistorNominal = 10000; // Thermistor resistance at 25 degrees Celsius
float temperatureNominal = 25; // Temperature at which thermistor resistance is nominal
float bCoefficient = 3950; // Beta coefficient of thermistor
float seriesResistor = 10000; // Resistance of series resistor
float thermistorResistance, temperatureC, temperatureF;

// defaults to TX pin if no pin specified, see IRsend::IRsend(int txpin) header for PWM pins available
IRsend irsend(SEND_PIN);

void setup() {
    pinMode(D7, OUTPUT);
    digitalWrite(D7, HIGH);
    irsend.sendNEC(0x1FF02FD, 32);
    digitalWrite(D7, LOW);
    // particle.variable("wakeup", data)
    Particle.function("wakeup", testData);

void loop() {
    int reading = analogRead(ky013Pin); // Read analog input
    float voltage = reading * (3.3 / 4095.0); // Convert reading to voltage87
    thermistorResistance = seriesResistor * (3.3 / voltage - 1); // Calculate thermistor resistance
    temperatureC = 1 / (log(thermistorResistance / thermistorNominal) / bCoefficient + 1 / (temperatureNominal + 273.15)) - 273.15; // Calculate temperature in degrees Celsius
    temperatureF = temperatureC * 9.0 / 5.0 + 32.0; // Convert temperature to degrees Fahrenheit
    Particle.publish("Temp:", String(temperatureC));


void makeJSON(){
    char jsonStr[600] = "na";
    char jsonTimeStr[12] = "na";

    sprintf(jsonTimeStr, "%d:%.2d:%.2d", Time.hour(), Time.minute(), Time.second());

    sprintf(jsonStr,  "{\"updated\":%u, \"temperatureC\":%d}",
            jsonTimeStr, temperatureC);

    if(Particle.connected() && strlen(jsonStr) < 600) {
        Particle.publish("hook-range", jsonStr);

// Receive data From Form post

int testData(String cmd) {
    Particle.publish("Data", cmd);
    if (cmd == "off") {
        digitalWrite(D7, HIGH);
        digitalWrite(D7, LOW);
    return 1;

Here’s my website code:

// Get the data from particle-argon.
if(empty($_POST['event'])) {
    echo "No webhooks recieved. <br>";
} elseif($_POST['event'] == 'hook-range') {

    $eventData = $_POST['data'];
    $eventData = json_decode($eventData);

    file_put_contents('alien-webhook.json', json_encode($eventData));

$jsonData = json_decode(file_get_contents('alien-webhook.json'), true);

Welcome to the Particle Forum!

Two quick suggestions:

  1. At the bottom of the page on the integration tab where you have defined your webhook, there is a twisty for “logs”. Here is an example of the information you will find there - it may help you see what is going on (careful when you share these views as some information is best kept private).

  1. When I am troubleshooting web hooks, I often use Postman to send web hooks. This gives you more control over what you send and more information as well. Also, it lets you isolate the problem by taking Particle out of the picture until you are sure your website it doing its part.

Hope this helps,



Another thing to look at is if your server is reachable from the outside world.
I do not know your infrastructure, so I can’t say whether the server is exposed on the internet or not:

Reaching it from your computer (if you are on the same local network) may not indicate that it works well. It has to be reachable from the outside world for the Particle webhook to hit it.
