Use the InfluxDB v2 API with InfluxDB Cloud Serverless

InfluxDB Cloud Serverless is compatible with the InfluxDB v2 API /api/v2/write endpoint and existing InfluxDB 2.x tools and code. Use the InfluxDB v2 API for new write workloads and existing v2 write workloads that you bring to InfluxDB Cloud Serverless.

InfluxDB v2 API endpoints won’t work for managing resources or querying data in InfluxDB Cloud Serverless. To query data, use the Flight+gRPC protocol or the InfluxDB v1 /query HTTP API endpoint and associated tools.

Authenticate API requests

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

Authenticate with a token

Use the Authorization: Token scheme to pass an API token that has the necessary permissions for the operation.

The Token scheme is used in the InfluxDB 2.x API.

Syntax

Authorization: Token API_TOKEN

Examples

Use Token to authenticate a write request:

# Use the Token authentication scheme with /api/v2/write
curl --post "https://cloud2.influxdata.com/api/v2/write?bucket=
BUCKET_NAME
&precision=s"
\
--header "Authorization: Token
API_TOKEN
"
\
--data-binary 'home,room=kitchen temp=72 1463683075'

Replace the following:

  • BUCKET_NAME: your InfluxDB Cloud Serverless bucket
  • API_TOKEN: an API token with sufficient permissions to the specified bucket

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 Serverless 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 bucket 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://cloud2.influxdata.com/api/v2/write

/api/v2/write parameters

For InfluxDB Cloud Serverless 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 *HeaderHonoredToken API_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 Serverless /api/v2/write endpoint:

Telegraf

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

Interactive clients

To test InfluxDB v2 API writes interactively from the command line, 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.

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 v3 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 Serverless 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 Serverless supports many different tools for querying data, including:

Avoid using /api/v2/query

Avoid using the /api/v2/query API endpoint in InfluxDB Cloud Serverless and associated tooling, such as the influx query CLI command and InfluxDB v2 client libraries. You can’t use SQL or InfluxQL with these tools.

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.
