InfluxDB is a time series database written in Go.
Writing Data
The schema of a InfluxDB database is based on the very first initial data types added. Adding additional data with a different type will be rejected.

- https://www.influxdata.com/blog/how-to-send-sensor-data-to-influxdb-from-an-arduino-uno/
Curl
Using curl, you can POST values to a particular database using the line protocol. For more information, see https://docs.influxdata.com/influxdb/v0.9/write_protocols/line/
$ curl -X POST 'http://influxdb/write?db=lsf' --data-binary 'measurement,tag1=x,tag2=x recorded_value1=x `date +%s"000000000"`'
For multiple entries, write multiple lines separated by a \n newline and POST with Curl like above.
$ cat /tmp/measurements | curl -X POST 'http://influxdb/write?db=lsf' --data-binary @-'
