# particle webhooks
|
||||
|
||||
You should configure your Particle.io's Webhooks to point at the `webhooks` service. To do this go to `(https://console.particle.io/)[https://console.particle.io]` and click `Integrations > New Integration > Webhook`. In the resulting page set `URL` to `http://<my_ip>:1619/particle`, and under `Advanced Settings` click on `JSON` and add:
|
||||
|
||||
```
|
||||
{
|
||||
"influx_db": "your_measurement_name"
|
||||
}
|
||||
```
|
||||
|
||||
If required, enter your username and password, etc. and then click `Save`
|
||||
|
||||
|
||||
## Events
|
||||
|
||||
Your Particle device should publish an event that contains a JSON in the form of:
|
||||
```
|
||||
String data = String::format("{ \"tags\" : {
|
||||
\"tag_name\": \"tag_value\",
|
||||
\"other_tag\": \"other_value\"
|
||||
},
|
||||
\"values\": {
|
||||
\"value_name\": %f,
|
||||
\"other_value\": %f,
|
||||
}
|
||||
}", value_value, other_value
|
||||
);
|
||||
Particle.publish("event_name", data, PRIVATE);
|
||||
```
|
||||
Escaping the "" is required in the source file on the Particle device.
|
||||
The number of tag values and field values is not restricted so you can send as many values per webhook call as you'd like.
|
||||
|
||||
|
||||
|
||||
See [webhook doc](https://docs.particle.io/reference/webhooks/)
