[SOLVED] Issue creating a webhook for Particle photon


I got my project working, but I am trying to streamline it a little bit and leverage some of the additional features offered by Particle Cloud, primarily webhooks, to post data to ubidots.

I have created the following webhook, based on Ubidots documentation:

    "event": "Ubidots",
    "url": "https://industrial.api.ubidots.com/api/v1.6/devices/{{{PARTICLE_DEVICE_ID}}}",
    "requestType": "POST",
    "noDefaults": false,
    "rejectUnauthorized": true,
    "headers": {
        "X-Auth-Token": "XXXXXX",
        "Content-Type": "application/json"
    "body": "{{{PARTICLE_EVENT_VALUE}}}"

And for the life of me, I can’t figure out why it is not working. I created the webhook and then clicked on “Test” and it gave me an error status 400 from industrial.api.ubidots.com.
In my application if, instead of using UBI_PARTICLE when defining my ubidots, I use UBI_HTTP, my code works perfectly fine.
Here is my simple code to test it:

#include <Ubidots.h>

Ubidots ubidots("webhook", UBI_PARTICLE);

void setup() {
  // Put initialization like pinMode and begin functions here.
  Particle.subscribe("hook-response/Ubidots", ubidotsHandler, MY_DEVICES);

// loop() runs over and over again, as quickly as it can execute.
void loop() {
  Serial.println("main: Starting loop");
  // The core of your code will likely live here.
  Serial.println("main: posting data to ubidots");
  ubidots.add("sensor-0", 12345);
  ubidots.add("sensor-1", 67890);
  bool bufferSent = false;
  bufferSent = ubidots.send("Ubidots", PUBLIC);
  if(bufferSent) {
    Serial.println("main: data sent correctly to ubidots");

void ubidotsHandler(const char *event, const char *data) {
  Serial.printlnf("ubidotsHandler: data = %s", data);
  if(!data) {
    Particle.publish("ubidotsResp", "No data");
  int respCode = atoi(data);
  if((respCode == 200 || respCode == 201)) {
    Particle.publish("ubidotsHook", "Success");
  } else {
    Particle.publish("ubidotsHook", data);

In my event log, I can see the hook-set/Ubidots, but then followed by hook-error/Ubidots.
Any idea where the issue is.

Thanks a lot in advance,

Hi there, can you post the payload that is being sent to Ubidots? Additionally, can you try with the basic example as well?

All the best

@jotathebest, I have managed to fix the issue. Apparently, the test feature, used to validate a webhook in the Particle Console, doesn’t work with Ubidots. Once I ignored that and actually tested it, it worked fine.

Nice to know that it worked for you, the particle console utility just works if you set both fixed device label and payload.

Enjoy using Ubidots.
