To send data to one variable, make a POST request to the following URL:

HTTP Method	URL
POST	`https://industrial.api.ubidots.com/api/v1.6/variables/<variable_id>/values`

<variable_id> is a string with the ID of the variable to which data will be sent.

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 for the account.
`Content-Type`	`application/json`	Yes	The data type of the body.

Body

An object containing either a single value, a single Dot, or multiple Dots. The following are all valid payloads:

{
  "value": 10
}

{
  "value": 10,
  "timestamp": 1635369947000,
  "context": {}
}

// Each value in the array must have its own timestamp
[
  {
    "value": 10,
    "timestamp": 1635369947000
  },
  {
    "value": 11,
    "timestamp": 1635369948000
  },
  {
    "value": 12,
    "timestamp": 1635369949000
  }
]

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

📘
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 your request URL:

Parameter	Type	Description
token	String	The token to authenticate the request. Although sending it as a query parameter is supported, we strongly recommend using the `X-Auth-Token` header.

Examples

Send a value to a variable:
Update a variable and let Ubidots apply a timestamp equal to the time of receipt:

$ curl -X POST 'https://industrial.api.ubidots.com/api/v1.6/variables/<variable_id>/values' \
 -H 'Content-Type: application/json' \
 -H 'X-Auth-Token: oaXBo6ODhIjPsusNRPUGIK4d72bc73' \
 -d '{"value": 27}'

{
  "value": 27,
  "timestamp": 1635371040531,
  "context": {},
  "created_at": 1635371040531
}

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

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

Send a Dot to a variable:
Update a variable with a timestamp and context:

 -d '{
   "value":27,

   "context":{
      "status":"warm"
   }

Send multiple Dots to a variable:
Update a variable with multiple Dots, including their timestamps:

$ curl -X POST 'https://industrial.api.ubidots.com/api/v1.6/variables/<variable_id>/values' \
 -H 'Content-Type: application/json' \
 -H 'X-Auth-Token: oaXBo6ODhIjPsusNRPUGIK4d72bc73' \
 -d '[
  {
    "value": 10,

Update a position variable so that the device displays its location:

curl -X POST 'https://industrial.api.ubidots.com/api/v1.6/variables/<variable_id>/values' \
 -H 'Content-Type: application/json' \
 -H 'X-Auth-Token: oaXBo6ODhIjPsusNRPUGIK4d72bc73' \
