Write data

Download InfluxDB API Spec
Write time series data to InfluxDB OSS v2 buckets in line protocol format using the /api/v2/write endpoint.
POST /api/v2/write

Write data

Writes data to a bucket.

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

InfluxDB Cloud

  • Does the following when you send a write request:

    1. Validates the request and queues the write.
    2. If queued, responds with success (HTTP 2xx status code); error otherwise.
    3. Handles the delete asynchronously and reaches eventual consistency.

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

    Because writes and deletes are asynchronous, your change might not yet be readable when you receive the response.

InfluxDB OSS v2

  • Validates the request and handles the write synchronously.
  • If all points were written successfully, responds with HTTP 2xx status code; otherwise, returns the first line that failed.

Required permissions

  • write-buckets or write-bucket BUCKET_ID.

BUCKET_ID is the ID of the destination bucket.

Rate limits (with InfluxDB Cloud)

write rate limits apply. For more information, see limits and adjustable quotas.

Parameters

Query parameters
org required string

An organization name or ID.

InfluxDB Cloud

  • Doesn’t use the org parameter or orgID parameter.
  • Writes data to the bucket in the organization associated with the authorization (API token).

InfluxDB OSS v2

  • Requires either the org parameter or the orgID parameter.
  • If you pass both orgID and org, they must both be valid.
  • Writes data to the bucket in the specified organization.
orgID string

An organization ID.

InfluxDB Cloud

  • Doesn’t use the org parameter or orgID parameter.
  • Writes data to the bucket in the organization associated with the authorization (API token).

InfluxDB OSS v2

  • Requires either the org parameter or the orgID parameter.
  • If you pass both orgID and org, they must both be valid.
  • Writes data to the bucket in the specified organization.
bucket required string
A bucket name or ID. InfluxDB writes all points in the batch to the specified bucket.
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.

InfluxDB Cloud

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

InfluxDB OSS v2

  • Returns only application/json for format and 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.

InfluxDB Cloud

  • Validated and queued the request.
  • Handles the write asynchronously - the write might not have completed yet.

InfluxDB OSS v2

  • Successfully wrote all points in the batch.
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. The response body contains the first malformed line in the data, and indicates what was expected.

InfluxDB Cloud

  • Returns this error for bucket schema conflicts.

InfluxDB OSS v2

  • Returns this error if the org parameter or orgID parameter doesn’t match an organization.
code required string
Code is the machine-readable error code.
Allowed: internal error , not found , conflict , invalid , empty value , unavailable
err string
Stack of errors that occurred during processing of the request. Useful for debugging.
line integer <int32>
First line in the request body that contains malformed data.
message string
Human-readable message.
op string
Describes the logical code operation when the error occurred. Useful for debugging.
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 this organization and bucket.
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.

413

The request payload is too large. InfluxDB rejected the batch and did not write any data.

InfluxDB Cloud:

  • Returns this error if the payload exceeds the 50MB size limit.
  • Returns Content-Type: text/html for this error.

InfluxDB OSS v2:

code required string
Code is the machine-readable error code.
Allowed: invalid
message required string
Human-readable message.
422 The request was well-formed, but some or all the points were rejected due to semantic errors–for example, schema conflicts or retention policy violations. Error message contains details for one or more rejected points.

429

Too many requests.

InfluxDB Cloud

  • Returns this error if a read or write request exceeds your plan’s adjustable service quotas or if a delete request exceeds the maximum global limit.
  • For rate limits that reset automatically, returns a Retry-After header that describes when to try the write again.
  • For limits that can’t reset (for example, cardinality limit), doesn’t return a Retry-After header.

Rates (data-in (writes), queries (reads), and deletes) accrue within a fixed five-minute window. Once a rate limit is exceeded, InfluxDB returns an error response until the current five-minute window resets.

InfluxDB OSS v2

  • Doesn’t return this error.
500 Internal server error. The server encountered an unexpected situation.
