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

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

Headers

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

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

Body

An object containing the following key 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 note below for detailed explanation.
join_dataframes	Boolean	No	`true`: returns an array. Each element is an array containing the values for the period. `false`: { "h returns an array where each element is separate time-series per variable.
start	Number	No	Initial timestamp in milliseconds POSIX format (inclusive).
end	Number	No	Final timestamp in milliseconds POSIX format (inclusive).
tz	string	No	The timezone in which the timestamps provided in the request are interpreted.
precision	integer	No	The decimal places to be used for data aggregation.

📘
Period parameter
Available resample 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 and end are included, the request will use the last 100 values of each variable.

If only start is sent, it will include values from that timestamp up until current date.

If only end is sent, it will includes values from the beginning of data reception up until that timestamp.

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

Query Parameters

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

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
