To resample data from one or multiple variables over a time range with a given resampling period, make a POST request to the following URL:

HTTP Method	URL
POST	`https://industrial.api.ubidots.com/api/v1.6/data/stats/resample/`

Headers

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

Header	Value	Required?	Description
`X-Auth-Token`	Token	Yes	The account's authentication token.
`Content-Type`	`application/json`	Yes	The content type of the request body.

Body

The request body is an object containing the following parameters:

Parameter	Type	Required?	Description
variables	String Array	Yes	An array of variable IDs.
aggregation	String	Yes	The aggregation to apply. Possible values are `mean`, `min`, `max`, `count`, `sum`.
period	String	Yes	Resampling period. See the note below for a detailed explanation.
join_dataframes	Boolean	No	`true`: returns an array where each element contains the values for the period. `false`: returns an array where each element is a separate time series for a variable.
start	Number	No	Initial timestamp in POSIX format, in milliseconds (inclusive).
end	Number	No	Final timestamp in POSIX format, in milliseconds (inclusive).
tz	string	No	The time zone in which the timestamps provided in the request are interpreted.
precision	integer	No	The number of decimal places to use for data aggregation.

📘
Period parameter
Available resampling periods are:

"nT": Every n minutes

"nH": Every n hours

"nD": Every n days

"W": Every end of week

"M": Every end of month

📘
Optional parameters

If neither start nor end is included, the request uses the last 100 values of each variable.

If only start is sent, the request includes values from that timestamp up to the current date.

If only end is sent, the request includes values from the beginning of data reception up to that timestamp.

If the precision key is not defined, decimal numbers are displayed according to the calculation.

Query Parameters

You may add optional parameters to the request URL:

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

Examples

Resample every 1 hour and return a combined time-aligned dataset
Get the mean value from multiple variables over a 5-hour time range, resampled every 1 hour. The response returns a single, combined dataset aligned by timestamp.

Resample every 1 hour and return separate time-series per variable
Get the mean value from multiple variables over a 5-hour time range, resampled every 1 hour. The response returns independent time-series for each variable.
