# Send data from Elastic Bulk API to Axiom





Axiom is a log management platform that offers an Elasticsearch Bulk API emulation to facilitate migration from Elasticsearch or integration with tools that support the Elasticsearch Bulk API.

Using the Elastic Bulk API and Axiom in your app provides a robust way to store and manage logs.

The Elasticsearch Bulk API expects the timestamp to be formatted as `@timestamp`, not `_time`. For example:

```json
{"index": {"_index": "myindex", "_id": "1"}}
{"@timestamp": "2024-01-07T12:00:00Z", "message": "axiom elastic bulk", "severity": "INFO"}
```

## Send logs to Axiom using the Elasticsearch Bulk API and Go [#send-logs-to-axiom-using-the-elasticsearch-bulk-api-and-go]

To send logs to Axiom using the Elasticsearch Bulk API and Go, use the `net/http` package to create and send the HTTP request.

### Prepare your data [#prepare-your-data]

The data needs to be formatted as per the Bulk API’s requirements. Here’s a simple example of how to prepare your data:

```json
data :=
{"index": {"_index": "myindex", "_id": "1"}}
{"@timestamp": "2023-06-06T12:00:00Z", "message": "axiom elastic bulk", "severity": "INFO"}
{"index": {"_index": "myindex", "_id": "2"}}
{"@timestamp": "2023-06-06T12:00:01Z", "message": "axiom elastic bulk api", "severity": "ERROR"}
```

### Send data to Axiom [#send-data-to-axiom]

Get an Axiom [API token](/reference/tokens) for the Authorization header, and create a [dataset](/reference/datasets).

```go
package main

import (
	"bytes"
	"fmt"
	"io/ioutil"
	"log"
	"net/http"
)

func main() {
	data := []byte(`{"index": {"_index": "myindex", "_id": "1"}}
{"@timestamp": "2023-06-06T12:00:00Z", "message": "axiom elastic bulk", "severity": "INFO"}
{"index": {"_index": "myindex", "_id": "2"}}
{"@timestamp": "2023-06-06T12:00:01Z", "message": "axiom elastic bulk api", "severity": "ERROR"}
`)

	// Create a new request using http
	req, err := http.NewRequest("POST", "https://AXIOM_DOMAIN:443/v1/ingest/DATASET_NAME/elastic/_bulk", bytes.NewBuffer(data))
	if err != nil {
		log.Fatalf("Error creating request: %v", err)
	}

	// Add authorization header to the request
	req.Header.Add("Authorization", "Bearer API_TOKEN")
	req.Header.Add("Content-Type", "application/x-ndjson")

	// Send request using http.Client
	client := &http.Client{}
	resp, err := client.Do(req)
	if err != nil {
		log.Fatalf("Error on response: %v", err)
	}
	defer resp.Body.Close()

	// Read and print the response body
	body, err := ioutil.ReadAll(resp.Body)
	if err != nil {
		log.Fatalf("Error reading response body: %v", err)
	}
	fmt.Printf("Response status: %s\nResponse body: %s\n", resp.Status, string(body))
}
```

## Send logs to Axiom using the Elasticsearch Bulk API and Python [#send-logs-to-axiom-using-the-elasticsearch-bulk-api-and-python]

To send logs to Axiom using the Elasticsearch Bulk API and Python, use the built-in `requests` library.

### Prepare your data [#prepare-your-data-1]

The data sent needs to be formatted as per the Bulk API’s requirements. Here’s a simple example of how to prepare the data:

```json
data = """
{"index": {"_index": "myindex", "_id": "1"}}
{"@timestamp": "2023-06-06T12:00:00Z", "message": "Log message 1", "severity": "INFO"}
{"index": {"_index": "myindex", "_id": "2"}}
{"@timestamp": "2023-06-06T12:00:01Z", "message": "Log message 2", "severity": "ERROR"}
"""
```

### Send data to Axiom [#send-data-to-axiom-1]

Obtain an Axiom [API token](/reference/tokens) for the Authorization header, and [dataset](/reference/datasets).

```py
import requests
import json

data = """
{"index": {"_index": "myindex", "_id": "1"}}
{"@timestamp": "2024-01-07T12:00:00Z", "message": "axiom elastic bulk", "severity": "INFO"}
{"index": {"_index": "myindex", "_id": "2"}}
{"@timestamp": "2024-01-07T12:00:01Z", "message": "Log message 2", "severity": "ERROR"}
"""

# Replace these with your actual dataset name and API token
dataset = "DATASET_NAME"
api_token = "API_TOKEN"

# The URL for the bulk API
url = f'https://AXIOM_DOMAIN:443/v1/ingest/{dataset}/elastic/_bulk'

try:
    response = requests.post(
        url,
        data=data,
        headers={
            'Content-Type': 'application/x-ndjson',
            'Authorization': f'Bearer {api_token}'
        }
    )
    response.raise_for_status()
except requests.HTTPError as http_err:
    print(f'HTTP error occurred: {http_err}')
    print('Response:', response.text)
except Exception as err:
    print(f'Other error occurred: {err}')
else:
    print('Success!')

    try:
        print(response.json())
    except json.JSONDecodeError:
        print(response.text)
```

## Send logs to Axiom using the Elasticsearch Bulk API and PHP [#send-logs-to-axiom-using-the-elasticsearch-bulk-api-and-php]

To send logs from PHP to Axiom using the Elasticsearch Bulk API, make sure you have installed the necessary PHP libraries: [Guzzle](https://docs.guzzlephp.org/en/stable/overview.html) for making HTTP requests and [JsonMachine](https://packagist.org/packages/halaxa/json-machine) for handling newline-delimited JSON data.

### Prepare your data [#prepare-your-data-3]

The data sent needs to be formatted as per the Bulk API’s requirements. Here’s a simple example of how to prepare the data:

```json
$data = <<<EOD
{"index": {"_index": "myindex", "_id": "1"}}
{"@timestamp": "2023-06-06T12:00:00Z", "message": "Log message 1", "severity": "INFO"}
{"index": {"_index": "myindex", "_id": "2"}}
{"@timestamp": "2023-06-06T12:00:01Z", "message": "Log message 2", "severity": "ERROR"}
EOD;
```

### Send data to Axiom [#send-data-to-axiom-3]
