# Send logs

`POST /v1/input`

> **Deprecated.**

Send your logs to your Datadog platform over HTTP. Limits per HTTP request are:

- Maximum content size per payload (uncompressed): 5MB
- Maximum size for a single log: 1MB
- Maximum array size if sending multiple logs in an array: 1000 entries

Any log exceeding 1MB is accepted and truncated by Datadog:
- For a single log request, the API truncates the log at 1MB and returns a 2xx.
- For a multi-logs request, the API processes all logs, truncates only logs larger than 1MB, and returns a 2xx.

Datadog recommends sending your logs compressed.
Add the `Content-Encoding: gzip` header to the request when sending compressed logs.

The status codes answered by the HTTP API are:
- 200: OK
- 400: Bad request (likely an issue in the payload formatting)
- 403: Permission issue (likely using an invalid API Key)
- 413: Payload too large (batch is above 5MB uncompressed)
- 5xx: Internal error, request should be retried after some time

## Query parameters

- `ddtags` string

## Headers

- `Content-Encoding` 'gzip' | 'deflate' — HTTP header used to compress the media-type.

## Request body

- HTTPLogItem[] — Structured log message.
  - `ddsource` string — The integration name associated with your log: the technology from which the log originated. When it matches an integration name, Datadog automatically installs the corresponding parsers and facets. See [reserved attributes](https://docs.datadoghq.com/logs/log_collection/#reserved-attributes).
  - `ddtags` string — Tags associated with your logs.
  - `hostname` string — The name of the originating host of the log.
  - `message` string, required — The message [reserved attribute](https://docs.datadoghq.com/logs/log_collection/#reserved-attributes) of your log. By default, Datadog ingests the value of the message attribute as the body of the log entry. That value is then highlighted and displayed in the Logstream, where it is indexed for full text search.
  - `service` string — The name of the application or service generating the log events. It is used to switch from Logs to APM, so make sure you define the same value when you use both products. See [reserved attributes](https://docs.datadoghq.com/logs/log_collection/#reserved-attributes).

## Response `200`

Response from server (always 200 empty JSON).

- object

## Other responses

- `400` — unexpected error
- `429` — Too many requests
