/write 1.x compatibility API

If you have an existing bucket that doesn’t follow the database/retention-policy naming convention, you must manually create a database and retention policy mapping to write data to that bucket with the /write compatibility API.

Use one of the following authentication methods:

token authentication
basic authentication with username and password
query string authentication with username and password

Include your line protocol in the request body. Binary encode the line protocol to prevent unintended formatting. The examples use the curl --data-binary flag to binary encode the line protocol.

(Optional) The 1.x username to authenticate the request. See query string authentication.

(Required) The database to write data to. This is mapped to an InfluxDB . See Database and retention policy mapping.

The retention policy to write data to. This is mapped to an InfluxDB . See Database and retention policy mapping.

ns - nanoseconds
or µ - microseconds
ms - milliseconds
s - seconds
m - minutes
h - hours

Write data to a non-default retention policy
Use curl to write data from a file

Write data using basic authentication

curl --request POST http://localhost:8086/write?db=mydb \
  --user "INFLUX_USERNAME:INFLUX_PASSWORD_OR_TOKEN" \

Write data using token authentication

Write data to a non-default retention policy

curl --request POST http://localhost:8086/write?db=mydb&rp=customrp \
  --header "Authorization: Token INFLUX_API_TOKEN" \
  --data-binary "measurement,host=host1 field1=2i,field2=2.0 1577836800000000000"

Write multiple lines of line protocol

Write data with millisecond Unix timestamps

curl --request POST http://localhost:8086/write?db=mydb&precision=ms \
  --header "Authorization: Token INFLUX_API_TOKEN" \
  --data-binary "measurement,host=host1 field1=2i,field2=2.0 1577836800000"

Replace the following:

INFLUX_USERNAME:
: InfluxDB 1.x password or InfluxDB API token
