Use the InfluxDB v2 API with InfluxDB Clustered

Limited availability

InfluxDB Clustered is currently only available to a limited group of InfluxData customers. If interested in being part of the limited access group, please contact the InfluxData Sales team.

Use the InfluxDB v2 API /api/v2/write endpoint for new write workloads and existing v2 write workloads that you bring to InfluxDB Clustered. Learn how to authenticate requests, adjust request parameters for existing v2 workloads, and find compatible tools for writing and querying data stored in an InfluxDB Clustered database.

For help finding the best workflow for your situation, contact Support.

Authenticate API requests

InfluxDB API endpoints require each request to be authenticated with a database token.

Authenticate with a token

Use the Authorization: Bearer scheme or the Authorization: Token scheme to pass a database token that has the necessary permissions for the operation.

Bearer and Token are equivalent in InfluxDB Clustered. The Token scheme is used in the InfluxDB 2.x API. Bearer is defined by the OAuth 2.0 Framework. Support for one or the other may vary across InfluxDB API clients.


Authorization: Bearer DATABASE_TOKEN
Authorization: Token DATABASE_TOKEN


Use Bearer to authenticate a write request:

curl --request post '
--header 'Authorization: Bearer
--data-binary 'home,room=kitchen temp=72 1641024000'

Use Token to authenticate a write request:

curl --request post "
--header "Authorization: Token
--data-binary 'home,room=kitchen temp=72 1641024000'

Replace the following:

  • DATABASE_NAME: your InfluxDB Clustered database
  • DATABASE_TOKEN: a database token with sufficient permissions to the specified database


InfluxDB API responses use standard HTTP status codes. For successful writes, InfluxDB responds with a 204 No Content status code. Error responses contain a JSON object with code and message properties that describe the error. Response body messages may differ across InfluxDB Clustered v1 API, v2 API, InfluxDB Cloud, and InfluxDB OSS.

Error examples

  • Missing bucket value

    400 Bad Request
    { "code": "invalid",
      "message":"missing bucket value"

    The ?bucket= parameter value is missing in the request. Provide the database name.

  • Failed to deserialize org/bucket/precision

    400 Bad Request
    { "code":"invalid",
      "message":"failed to deserialize org/bucket/precision in request: unknown variant `u`, expected one of `s`, `ms`, `us`, `ns`"

    The ?precision= parameter contains an unknown value. Provide a timestamp precision.

Write data

We recommend using the InfluxDB v2 API /api/v2/write endpoint for new write workloads and existing v2 workloads.


/api/v2/write parameters

For InfluxDB Clustered v2 API /api/v2/write requests, set parameters as listed in the following table:

Parameter Allowed in Ignored Value
org Query string Ignored Non-zero-length string (ignored, but can’t be empty)
orgID Query string Ignored N/A
bucket * Query string Honored Database name
precision Query string Honored Timestamp precision
Accept Header Honored User-defined
Authorization * Header Honored Bearer DATABASE_TOKEN or Token DATABASE_TOKEN
Content-Encoding Header Honored gzip (compressed data) or identity (uncompressed)
Content-Length Header Honored User-defined
Content-Type Header Ignored N/A (only supports line protocol)
Zap-Trace-Span Header Ignored
* = Required

Timestamp precision

Use one of the following precision values in v2 API /api/v2/write requests:

  • ns: nanoseconds
  • us: microseconds
  • ms: milliseconds
  • s: seconds
  • m: minutes
  • h: hours

Tools for writing to the v2 API

The following tools work with the InfluxDB Clustered /api/v2/write endpoint:


See how to configure Telegraf to write to InfluxDB Clustered.

Interactive clients

To test InfluxDB v2 API writes interactively, use the influx3 data CLI or common HTTP clients such as cURL and Postman.

To setup and start using interactive clients, see the Get started tutorial.

influx CLI not supported

Don’t use the influx CLI with InfluxDB Clustered. While it may coincidentally work, it isn’t officially supported.

Client libraries

InfluxDB v3 client libraries and v2 client libraries can write data to the InfluxDB v2 API /api/v2/write endpoint. Client libraries are language-specific packages that integrate InfluxDB APIs with your application.

To setup and start using client libraries, see the Get started tutorial.

Query data

InfluxDB Clustered provides the following protocols for executing a query:

  • Flight+gRPC request that contains an SQL or InfluxQL query. To learn how to query InfluxDB Clustered using Flight and SQL, see the Get started tutorial.
  • InfluxDB v1 API /query request that contains an InfluxQL query.

Tools to execute queries

InfluxDB Clustered supports many different tools for querying data, including:

/api/v2/query not supported

The InfluxDB API /api/v2/query endpoint can’t query an InfluxDB cluster. The /api/v2/query API endpoint and associated tooling, such as the influx CLI and InfluxDB v2 client libraries, aren’t supported in InfluxDB Clustered.

The future of Flux

Flux is going into maintenance mode. You can continue using it as you currently are without any changes to your code.

Flux is going into maintenance mode and will not be supported in InfluxDB 3.0. This was a decision based on the broad demand for SQL and the continued growth and adoption of InfluxQL. We are continuing to support Flux for users in 1.x and 2.x so you can continue using it with no changes to your code. If you are interested in transitioning to InfluxDB 3.0 and want to future-proof your code, we suggest using InfluxQL.
