Use the InfluxDB v1 HTTP query API to query data in {{< product-name >}} with InfluxQL.

The examples below use cURL to send HTTP requests to the InfluxDB v1 HTTP API, but you can use any HTTP client.

InfluxQL feature support

InfluxQL is being rearchitected to work with the InfluxDB 3 storage engine. This process is ongoing and some InfluxQL features are still being implemented. For information about the current implementation status of InfluxQL features, see InfluxQL feature support. {{% /warn %}}

Use the v1 /query endpoint and the GET request method to query data with InfluxQL:

{{< api-endpoint endpoint="https://{{< influxdb/host >}}/query" method="get" api-ref="/influxdb3/clustered/api/#tag/Query" >}}

Provide the following with your request:

• Headers:
  • Authorization: Bearer DATABASE_TOKEN
• Query parameters:
  • db: the database to query
  • rp: Optional: the retention policy to query
  • q: URL-encoded InfluxQL query

{{% code-placeholders "DATABASE_(NAME|TOKEN)" %}}

curl --get https://{{< influxdb/host >}}/query \
  --header "Authorization: Bearer DATABASE_TOKEN" \
  --data-urlencode "db=DATABASE_NAME" \
  --data-urlencode "q=SELECT * FROM home"

{{% /code-placeholders %}}

Replace the following configuration values:

• {{% code-placeholder-key %}}DATABASE_NAME{{% /code-placeholder-key %}}: the name of the database to query.
• {{% code-placeholder-key %}}DATABASE_TOKEN{{% /code-placeholder-key %}}: a database token with read access to the specified database.

Authenticate with username and password

If using basic authentication or query string authentication (username and password) to interact with the v1 HTTP query API, provide the following credentials:

• username: an arbitrary string ({{< product-name >}} ignores the username)
• password: a database token with read access to the specified database.

{{< code-tabs-wrapper >}} {{% code-tabs %}} Basic Auth Query String Auth {{% /code-tabs %}}

{{% code-tab-content %}} {{% code-placeholders "DATABASE_(NAME|TOKEN)" %}}

curl --get https://{{< influxdb/host >}}/query \
  --header "Authorization: Basic ignored:DATABASE_TOKEN" \
  --data-urlencode "db=DATABASE_NAME" \
  --data-urlencode "q=SELECT * FROM home"

{{% /code-placeholders %}} {{% /code-tab-content %}}

{{% code-tab-content %}} {{% code-placeholders "DATABASE_(NAME|TOKEN)" %}}

curl --get https://{{< influxdb/host >}}/query \
  --data-urlencode "u=ignored" \
  --data-urlencode "p=DATABASE_TOKEN" \
  --data-urlencode "db=DATABASE_NAME" \
  --data-urlencode "q=SELECT * FROM home"

{{% /code-placeholders %}} {{% /code-tab-content %}}

{{< /code-tabs-wrapper >}} {{% /note %}}

Return results as JSON or CSV

By default, the /query endpoint returns results in JSON, but it can also return results in CSV. To return results as CSV, include the Accept header with the application/csv or text/csv MIME type:

{{% code-placeholders "DATABASE_(NAME|TOKEN)" %}}

curl --get https://{{< influxdb/host >}}/query \
  --header "Authorization: Token DATABASE_TOKEN" \
  --header "Accept: application/csv" \
  --data-urlencode "db=DATABASE_NAME" \
  --data-urlencode "q=SELECT * FROM home"
