Particle Cloud Webhook doesn't send data correctly

Cloud
1

Hi all,

I’m try to forward the device name, using a webhook to thingsboard. The device name is send by the Argon which it got earlier using the cloud. (Particle.subscribe("particle/device/name", handler);)

It all works fine. The data is correct on the Argon and also arrives correct in the cloud/event.

This is my data json file from the argon code:

  String  payload = "{";
          payload += "\"devName\":";     payload     += devName_S;           
          payload += "}";

Event in the webhook:


{
  "name": "Webhook",
  "data": "{\"devName\":Argon64002}",
  "ttl": 60,
  "published_at": "2019-05-08T15:52:00.560Z",
  "coreid": "XXXXXXXXXXXXXX"
}

Error response in the webhook:

Data in thingsboard from the data converter:
Unbenannt

and also the json format I want to send using the webhook:

{
  "devName": "{{{devName}}}"
}

I have no Idea why there is no data send. If I change the devName to the temperature I also want to send, everything is working as expected…

Any hints?

Your payload published by the device is not valid. The devName_S must also be surrounded by double quotes.

String  payload = "{";
payload += "\"devName\":\"";     
payload     += devName_S;           
payload += "\"}";

It should look like this in the console:

"data": "{\"devName\":\"Argon64002\"}",
