To send data to one or more variables of a Device, make a POST request to the following URL:

HTTP Method	URL
POST	`https://industrial.api.ubidots.com/api/v1.6/devices/<device_label>/`

Where <device_label> is the label of the Device that receives the data.

Headers

The "X-Auth-Token" and "Content-Type" headers are required in your request:

Header	Value	Required?	Description
`X-Auth-Token`	Token	Yes	Authentication Token of your account.
`Content-Type`	`application/json`	Yes	The media type of the request body.

Body

Send an object that contains variable labels as keys and Dots as values. The following payloads are valid:

{
  "temperature": 10,
  "humidity": 90,
  "pressure": 78
}

{
  "temperature": {
    "value": 10,
    "timestamp": 1634311791000,
    "context": {
      "status": "cold"
    }
  },
  "humidity": {
    "value": 90,
    "timestamp": 1634311791000,
    "context": {
      "status": "High humidity"
    }
  },
  "pressure": {
    "value": 78,
    "timestamp": 1634311791000,
    "context": {
      "status": "Normal"
    }
  }
}

{
  "position": {
    "value": 1, 
    "context": {
      "lat": "6.5423", 
      "lng": "-70.5783"
    }
  }
}

{
  "temperature": [{
    "value": 10,
    "timestamp": 1702933911000
  },
  {
    "value": 12,
    "timestamp": 1702933912000
  }]
}

For a detailed explanation of a Dot's keys, see How Ubidots works.

📘
timestamp and context
The timestamp and context parameters are optional.

🚧
Maximum length
The maximum character length for the body is 10 KB.

Query Parameters

You may add optional parameters to the URL of your request:

Parameter	Type	Description
timestamp	Integer	Optional. Timestamp in milliseconds in POSIX format. When present, this timestamp is applied to all Dots in the body unless a local timestamp is sent.
token	String	Optional. Token used to authenticate the request. Sending it as a query parameter is supported, but we strongly recommend using the `X-Auth-Token` header.
type	String	Optional. Device type label to apply to the Device if the Device doesn't exist yet. Learn more.
status	Boolean	Optional. When set to `true`, an additional `_status` object appears in the response. This object contains the IDs of the device and variables, as well as a `new` field indicating whether each resource was just created. Example:\ `{ "_status": { "_datasource": { "id": "61d8a6731d84726e96dba805", "new": false }, "temperature": { "id": "61d8a6751d84726d00e5b7b8", "new": true } }, "temperature": [ { "status_code": 201 } ] }`

Sending location data

You can use the context key to send location data. Ubidots automatically recognizes location data when you use these variable labels:

position
location
gps

There are three ways to send location data:

{
  "position": {
    "value": 1, 
    "context": {
      "lat": "6.5423", 
      "lng": "-70.5783"
    }
  }
}

// Because the "value" of a Dot is required, this option sets the variable value to "1".

{
  "position": {
      "lat": "6.5423", 
      "lng": "-70.5783"
    }
}

// Because the "value" of a Dot is required, this option sets the variable value to "1".

{
  "position": {
      "latitude": "6.5423", 
      "longitude": "-70.5783"
    }
}

📘
Location modes
The location of a Device can be determined by a variable or a fixed property. See Device Location modes to learn more.

Examples

Send a value to a single variable:
Update a variable and let Ubidots apply a timestamp equal to the reception time:

$ curl -X POST 'https://industrial.api.ubidots.com/api/v1.6/devices/<device_label>/' \
 -H 'Content-Type: application/json' \
 -H 'X-Auth-Token: oaXBo6ODhIjPsusNRPUGIK4d72bc73' \
 -d '{"temperature": 10}'

{
  "temperature":[{"status_code":201}]
}

{
  "code":400001,
  "message":"The payload sent is not a valid json document."
}

{
  "code":401001,
  "message":"Authentication credentials were not provided."
}

Send a value to multiple variables:
Update two variables and let Ubidots apply a timestamp equal to the reception time:

$ curl -X POST 'https://industrial.api.ubidots.com/api/v1.6/devices/<device_label>/' \
 -H 'Content-Type: application/json' \
 -H 'X-Auth-Token: oaXBo6ODhIjPsusNRPUGIK4d72bc73' \
 -d '{"temperature": 10, "humidity": 90}'

{
  "temperature":[{"status_code":201}],
  "humidity":[{"status_code":201}]
}

{
  "code":400001,
  "message":"The payload sent is not a valid json document."
}

{
  "code":401001,
  "message":"Authentication credentials were not provided."
}

Send Dots to multiple variables:
Update multiple variables, including context and timestamp:

$ curl -X POST 'https://industrial.api.ubidots.com/api/v1.6/devices/<device_label>/' \
 -H 'Content-Type: application/json' \
 -H 'X-Auth-Token: oaXBo6ODhIjPsusNRPUGIK4d72bc73' \
 -d '{
  "temperature": {
    "value": 10,
    "timestamp": 1634311791000,
    "context": {
      "status": "cold"
    }
  },
  "humidity": {
    "value": 90,
    "timestamp": 1634311791000,
    "context": {
      "status": "High humidity"
    }
  },
  "pressure": {
    "value": 78,
    "timestamp": 1634311791000,
    "context": {
      "status": "Normal"
    }
  }
}'

{
  "temperature":[{"status_code":201}],
  "humidity":[{"status_code":201}],
  "pressure":[{"status_code":201}]
}

{
  "code":400001,
  "message":"The payload sent is not a valid json document."
}

{
  "code":401001,
  "message":"Authentication credentials were not provided."
}

Send location data:
Update a position variable so that the Device displays its location:

curl -X POST 'https://industrial.api.ubidots.com/api/v1.6/devices/<device_label>/' \
 -H 'Content-Type: application/json' \
 -H 'X-Auth-Token: oaXBo6ODhIjPsusNRPUGIK4d72bc73' \
 -d '{"position":{"lat":6.2442, "lng":-75.5812}}'

{
  "position":[{"status_code":201}],
}

{
  "code":400001,
  "message":"The payload sent is not a valid json document."
}

{
  "code":401001,
  "message":"Authentication credentials were not provided."
}

Send data with global timestamp:
Update multiple variables with a global timestamp sent as a query parameter. Variables with an individual timestamp will override the global timestamp:

$ curl -X POST 'https://industrial.api.ubidots.com/api/v1.6/devices/<device_label>/?timestamp=1634311791000' \
 -H 'Content-Type: application/json' \
 -H 'X-Auth-Token: oaXBo6ODhIjPsusNRPUGIK4d72bc73' \
 -d '{
  "temperature": {
    "value": 10,
    "context": {
      "status": "cold"
    }
  },
  "humidity": {
    "value": 90,
    "context": {
      "status": "High humidity"
    }
  },
  "pressure": {
    "value": 78,
    "timestamp": 1634336087000,
    "context": {
      "status": "Normal"
    }
  }
}'

Send historical data to a Device (data logger):
Send multiple Dots per variable. Each Dot requires its own timestamp.

$ curl -X POST 'https://industrial.api.ubidots.com/api/v1.6/devices/<device_label>/' \
 -H 'Content-Type: application/json' \
 -H 'X-Auth-Token: oaXBo6ODhIjPsusNRPUGIK4d72bc73' \
 -d '{
  "temperature": [
    {"value": 10,"timestamp": 1634336087000},
    {"value": 11,"timestamp": 1634336088765}
  ],
  "humidity": [
    {"value": 90,"timestamp": 1634336087000},
    {"value": 95,"timestamp": 1634336088765}
  ],
  "pressure": [
    {"value": 78,"timestamp": 1634336087000},
    {"value": 82,"timestamp": 1634336088765}
  ]
}'
