Query with the InfluxDB API
This page documents an earlier version of InfluxDB OSS. InfluxDB 3 Core is the latest stable version.
The InfluxDB v2 API provides a programmatic interface for all interactions with InfluxDB. To query InfluxDB 2.7, do one of the following:
Send a Flux query request
Send a Flux query request to the following endpoint:
In your request, set the following:
- Your organization via the
orgororgIDURL parameters - Headers:
Authorization: Token <API_TOKEN>Accept: application/csvContent-type: application/vnd.flux
- Your Flux query text in the request body
Use gzip to compress a large query response
To compress the query response, set the Accept-Encoding header to gzip.
This saves network bandwidth, but increases server-side load.
We recommend only using gzip compression on responses that are larger than 1.4 KB. If the response is smaller than 1.4 KB, gzip encoding will always return a 1.4 KB response, despite the uncompressed response size. 1500 bytes (~1.4 KB) is the maximum transmission unit (MTU) size for the public network and is the largest packet size allowed at the network layer.
Flux - Example query request
The following example shows how to use cURL to send a Flux query to InfluxDB 2.7:
curl \
--request POST \
http://localhost:8086/api/v2/query?orgID=ORG_ID \
--header 'Authorization: Token API_TOKEN' \
--header 'Accept: application/csv' \
--header 'Content-type: application/vnd.flux' \
--data 'from(bucket:"BUCKET_NAME")
|> range(start: -12h)
|> filter(fn: (r) => r._measurement == "example-measurement")
|> aggregateWindow(every: 1h, fn: mean)'curl \
--request POST \
http://localhost:8086/api/v2/query?orgID=ORG_ID \
--header 'Authorization: Token API_TOKEN' \
--header 'Accept: application/csv' \
--header 'Content-type: application/vnd.flux' \
--header 'Accept-Encoding: gzip' \
--data 'from(bucket:"BUCKET_NAME")
|> range(start: -12h)
|> filter(fn: (r) => r._measurement == "example-measurement")
|> aggregateWindow(every: 1h, fn: mean)'Replace the following with your values:
ORG_ID- the ID of the organization that owns the bucket.API_TOKEN- your token.BUCKET_NAME- the name of the bucket to query.
Send an InfluxQL query request
To query InfluxDB 2.7 using the InfluxQL query language, send a request to the v1-compatible API endpoint:
In your request, set the following:
- 1.x-compatible or 2.x authentication credentials
- Headers:
Accept: application/csvorAccept: application/jsonContent-type: application/vnd.influxql
- The database and retention policy mapped to the bucket you want to query
- Your InfluxQL query text
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 query that bucket with the /query compatibility API.
Use the db and rp query parameters to specify the database and retention policy
for the bucket you want to query.
InfluxQL - Example query request
The following example shows how to use cURL to send an InfluxQL query to InfluxDB 2.7 using v1-compatible authentication:
# 1.x compatible POST request using Basic authentication and InfluxQL
curl --request POST \
"http://localhost:8086/query?db=BUCKET_NAME&p=API_TOKEN&u=ignored" \
--header "Content-type: application/vnd.influxql" \
--data "SELECT * FROM home WHERE time > now() - 1h"# 1.x compatible GET request using Basic authentication and InfluxQL
curl --get "http://localhost:8086/query" \
--header "Accept: application/json" \
--data-urlencode "q=SELECT * FROM home WHERE time > now() - 1h" \
--data-urlencode "db=BUCKET_NAME" \
--data-urlencode "u=ignored" \
--data-urlencode "p=API_TOKEN"Replace the following with your values:
curl --get "http://localhost:8086/query" \
--header 'Accept: application/csv' \
--header 'Content-type: application/json' \
--data-urlencode "db=BUCKET_NAME" \
--data-urlencode "p=API_TOKEN" \
--data-urlencode "u=ignored" \
--data-urlencode "q=SELECT used_percent FROM example-db.example-rp.example-measurement WHERE host=host1"curl --get "http://localhost:8086/query" \
--header 'Accept: application/csv' \
--header 'Content-type: application/json' \
--header 'Accept-Encoding: gzip' \
--data-urlencode "db=BUCKET_NAME" \
--data-urlencode "p=API_TOKEN" \
--data-urlencode "u=ignored" \
--data-urlencode "q=SELECT used_percent FROM example-db.example-rp.example-measurement WHERE host=host1"Replace the following with your values:
InfluxDB returns the query results in annotated CSV.
