Write data

Download Clustered Data API Spec
Write time series data to InfluxDB 3 Clustered databases using the v2-compatible /api/v2/write endpoint or the v1-compatible /write endpoint with line protocol.
POST /api/v2/write

Write data using the InfluxDB v2 HTTP API

Writes data to a database.

Use this endpoint to send data in line protocol format to InfluxDB.

InfluxDB does the following when you send a write request:

  1. Validates the request
  2. If successful, attempts to ingest the data; error otherwise.
  3. If successful, responds with success (HTTP 204 status code), acknowledging that the data is written and queryable; error otherwise.

To ensure that InfluxDB Cloud handles writes in the order you request them, wait for a success response (HTTP 2xx status code) before you send the next request.

Parameters

Query parameters
org required string

Ignored. An organization name or ID.

InfluxDB ignores this parameter; authorizes the request using the specified database token and writes data to the specified cluster database.

orgID string

Ignored. An organization ID.

InfluxDB ignores this parameter; authorizes the request using the specified database token and writes data to the specified cluster database.

bucket required string
A database name or ID. InfluxDB writes all points in the batch to the specified database.
precision string
The precision for unix timestamps in the line protocol batch.
Header parameters
Zap-Trace-Span string
OpenTracing span context
Content-Encoding string
The compression applied to the line protocol in the request payload. To send a gzip payload, pass Content-Encoding: gzip header.
Allowed values: gzip , identity
Default: identity
Content-Type string
The format of the data in the request body. To send a line protocol payload, pass Content-Type: text/plain; charset=utf-8.
Allowed values: text/plain , text/plain; charset=utf-8
Default: text/plain; charset=utf-8
Content-Length integer
The size of the entity-body, in bytes, sent to InfluxDB. If the length is greater than the max body configuration option, the server responds with status code 413.
Accept string

The content type that the client can understand. Writes only return a response body if they fail–for example, due to a formatting problem or quota limit.

  • Returns only application/json for format and limit errors.
  • Returns only text/html for some quota limit errors.
Allowed values: application/json
Default: application/json

Request body required

In the request body, provide data in line protocol format.

To send compressed data, do the following:

  1. Use gzip to compress the line protocol data.
  2. In your request, send the compressed data and the Content-Encoding: gzip header.
Content-Type: application/json

Responses

204 Success. Data is written and queryable.
400

Bad request. The response body contains detail about the error.

InfluxDB returns this error if the line protocol data in the request is malformed or contains a database schema conflict. The response body contains the first malformed line in the data, and indicates what was expected.

401

Unauthorized. The error may indicate one of the following:

  • The Authorization: Token header is missing or malformed.
  • The API token value is missing from the header.
  • The token doesn’t have sufficient permissions to write to or query the database.
code string
The HTTP status code description. Default is unauthorized.
Allowed: unauthorized
message string
A human-readable message that may contain detail about the error.
404

Not found. A requested resource was not found. The response body contains the requested resource type and the name value (if you passed it)–for example:

  • "organization name \"my-org\" not found"
  • "organization not found": indicates you passed an ID that did not match an organization.

Write data using the InfluxDB v1 HTTP API

Writes data to a database.

Use this InfluxDB v1-compatible endpoint to send data in line protocol format to InfluxDB using v1 API parameters and authorization.

InfluxDB does the following when you send a write request:

  1. Validates the request
