Use the InfluxDB v2 API with InfluxDB Cloud Dedicated

Use the InfluxDB v2 API /api/v2/write endpoint for new write workloads and existing v2 write workloads that you bring to InfluxDB Cloud Dedicated. 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 Cloud Dedicated 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 Cloud Dedicated. 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.

Syntax

Authorization: Bearer DATABASE_TOKEN
Authorization: Token DATABASE_TOKEN

Examples

Use Bearer to authenticate a write request:

########################################################
# Use the Bearer authorization scheme with /api/v2/write
# to write data.
########################################################

curl --request post 'https://cluster-id.a.influxdb.io/api/v2/write?bucket=
DATABASE_NAME
&precision=s'
\
--header 'Authorization: Bearer
DATABASE_TOKEN
'
\
--data-binary 'home,room=kitchen temp=72 1463683075'

Use Token to authenticate a write request:

########################################################
# Use the Token authentication scheme with /api/v2/write
# to write data.
########################################################

curl --request post "https://cluster-id.a.influxdb.io/api/v2/write?bucket=
DATABASE_NAME
&precision=s"
\
--header "Authorization: Token
DATABASE_TOKEN
"
\
--data-binary 'home,room=kitchen temp=72 1463683075'

Replace the following:

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

Responses

InfluxDB HTTP API responses use standard HTTP status codes. The response body for partial writes and errors contains a JSON object with code and message properties that describe the error. Response body messages may differ across InfluxDB Cloud Dedicated 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

Use the InfluxDB v2 API /api/v2/write endpoint for new write workloads and existing v2 workloads.

POST https://cluster-id.a.influxdb.io/api/v2/write

/api/v2/write parameters

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

ParameterAllowed inIgnoredValue
orgQuery stringIgnoredNon-zero-length string (ignored, but can’t be empty)
orgIDQuery stringIgnoredN/A
bucket *Query stringHonoredDatabase name
precisionQuery stringHonoredTimestamp precision
AcceptHeaderHonoredUser-defined
Authorization *HeaderHonoredBearer DATABASE_TOKEN or Token DATABASE_TOKEN
Content-EncodingHeaderHonoredgzip (compressed data) or identity (uncompressed)
Content-LengthHeaderHonoredUser-defined
Content-TypeHeaderIgnoredN/A (only supports line protocol)
Zap-Trace-SpanHeaderIgnored
* = 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 Cloud Dedicated /api/v2/write endpoint:

Telegraf

See how to configure Telegraf to write to InfluxDB Cloud Dedicated.

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 Cloud Dedicated. 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 Cloud Dedicated provides the following protocols for executing a query:

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

Tools to execute queries

InfluxDB Cloud Dedicated supports many different tools for querying data, including:

/api/v2/query not supported

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