# Backtest Report

[Documentation](https://www.quantconnect.com/docs/v2.md) > [Cloud Platform](https://www.quantconnect.com/docs/v2/cloud-platform.md) > [API Reference](https://www.quantconnect.com/docs/v2/cloud-platform/api-reference.md) > [Reports](https://www.quantconnect.com/docs/v2/cloud-platform/api-reference/reports.md) > Backtest Report

> Code examples are shown in Python. Append `?lang=csharp` to this URL for the C# version of this page.

## Introduction

Read out the report of a backtest.

## Request

A JSON object containing info about the backtest to use for the report. The `/backtests/read/report` API accepts requests in the following format:

| `BacktestReportRequest` Model - Request to read out the report of a backtest. |  |
| --- | --- |
| projectId | `integer required example: 23456789` Id of the project to read. |
| backtestId | `string required example: 26c7bb06b8487cff1c7b3c44652b30f1` Id of the backtest to read. |
| Example | `{ "projectId": 23456789, "backtestId": "26c7bb06b8487cff1c7b3c44652b30f1" }` |

## Responses

The `/backtests/read/report` API provides a response in the following format:

### 200 Success

| `BacktestReportGeneratingResponse` Model - Backtest Report Response wrapper. |  |
| --- | --- |
| generating | `boolean` Indicate if the report is generating. |
| success | `boolean` Indicate if the API request was successful. |
| errors | `string Array` List of errors with the API call. |
| Example | `{ "generating": true, "success": true, "errors": [ "string" ] }` |

| `BacktestReport` Model - Backtest Report Response wrapper. |  |
| --- | --- |
| report | `string` HTML data of the report with embedded base64 images. |
| success | `boolean` Indicate if the API request was successful. |
| errors | `string Array` List of errors with the API call. |
| Example | `{ "report": "string", "success": true, "errors": [ "string" ] }` |

### 401 Authentication Error

| `UnauthorizedError` Model - Unauthorized response from the API. Key is missing, invalid, or timestamp is too old for hash. |  |
| --- | --- |
| www_authenticate | `string` Header |

## Examples

The following example demonstates creating, reading, updating, deleting, and listing backtests of a project through the cloud API.

```
from base64 import b64encode
from hashlib import sha256
from time import time
from requests import get, post
BASE_URL = 'https://www.quantconnect.com/api/v2/'

# You need to replace these with your actual credentials.
# You can request your credentials at https://www.quantconnect.com/settings/
# You can find our organization ID at https://www.quantconnect.com/organization/
USER_ID = 0
API_TOKEN = '____'
ORGANIZATION_ID = '____'

def get_headers():
    # Get timestamp
    timestamp = f'{int(time())}'
    time_stamped_token = f'{API_TOKEN}:{timestamp}'.encode('utf-8')

    # Get hased API token
    hashed_token = sha256(time_stamped_token).hexdigest()
    authentication = f'{USER_ID}:{hashed_token}'.encode('utf-8')
    authentication = b64encode(authentication).decode('ascii')

    # Create headers dictionary.
    return {
        'Authorization': f'Basic {authentication}',
        'Timestamp': timestamp
    }

# Authenticate to verify credentials
response = post(f'{BASE_URL}/authenticate', headers = get_headers())
print(response.json())

# --------------------

### Create Backtest
# Define placeholder compilation ID (replace with actual value)
compile_id = "compile_id..."
# Send a POST request to the /backtests/create endpoint to create a backtest
response = post(f'{BASE_URL}/backtests/create', headers=get_headers(), json={
    "projectId": project_id,  # ID of the project to backtest
    "compileId": compile_id,  # Compilation ID for the backtest
    "backtestName": f"Backtest {int(time())}"  # Unique name for the backtest using current timestamp
})
# Parse the JSON response into python managable dict
result = response.json()
# Extract the backtest ID from the response
backtest_id = result['backtest']['backtestId']
# Check if the request was successful and print the result
if result['success']:
    print("Backtest Created Successfully:")
    print(result)

### Read Backtest Statistics
# Prepare data payload to read backtest statistics
payload = {
    "projectId": project_id,  # ID of the project
    "backtestId": backtest_id  # ID of the backtest to read
}
# Send a POST request to the /backtests/read endpoint to get statistics
response = post(f'{BASE_URL}/backtests/read', headers=get_headers(), json=payload)
# Parse the JSON response into python managable dict
result = response.json()
# Check if the request was successful and print the statistics
if result['success']:
    print("Backtest Statistics:")
    print(result)

### Read Backtest Logs
# Prepare data payload to read the first 200 log lines
payload = {
    "projectId": project_id,  # ID of the project
    "backtestId": backtest_id,  # ID of the backtest to read
    "start": 0,  # Start line (inclusive)
    "end": 200,  # End line (exclusive), at most 200 lines per request
    "query": None  # Keyword to filter the lines, or None to read all of them
}
# Send a POST request to the /backtests/read/log endpoint to get the logs
response = post(f'{BASE_URL}/backtests/read/log', headers=get_headers(), json=payload)
# Parse the JSON response into python managable dict
result = response.json()
# Check if the request was successful and print the logs
if result['success']:
    print("Backtest Logs:")
    print(result)

### Update Backtest
# Send a POST request to the /backtests/update endpoint to update backtest details

    "name": f"Backtest_{backtest_id}",  # New name for the backtest
    "note": "The new backtest name is awesome!"  # Additional note
})
# Parse the JSON response into python managable dict
result = response.json()
# Check if the request was successful and print the result
if result['success']:
    print("Backtest Updated Successfully:")
    print(result)

### Delete Backtest
# Prepare data payload to delete the backtest
payload = {
    "projectId": project_id,  # ID of the project

# Send a POST request to the /backtests/delete endpoint to delete the backtest
response = post(f'{BASE_URL}/backtests/delete', headers=get_headers(), json=payload)
# Parse the JSON response into python managable dict
result = response.json()
# Check if the request was successful and print the result
if result['success']:
    print("Backtest Deleted Successfully:")
    print(result)

### List Backtests
# Prepare data payload to list backtests with statistics
payload = {
    "projectId": project_id,  # ID of the project
    "includeStatistics": True  # Include statistics in the response
}
# Send a POST request to the /backtests/list endpoint to list backtests
response = post(f'{BASE_URL}/backtests/list', headers=get_headers(), json=payload)
# Parse the JSON response into python managable dict
result = response.json()
# Check if the request was successful and print the list
if result['success']:
    print("List of Backtests:")
    print(result)

### Export Orders
# Download the orders of the backtest as a CSV file
payload = {
    "backtestId": backtest_id  # ID of the backtest
}
response = post(f'{BASE_URL}/backtests/export/orders', headers=get_headers(), json=payload)
with open(f'orders-{backtest_id}.csv', 'w', newline='') as file:
    file.write(response.text)

### Export Trades
# Download the closed trades of the backtest as a CSV file
payload = {
    "backtestId": backtest_id  # ID of the backtest
}
response = post(f'{BASE_URL}/backtests/export/trades', headers=get_headers(), json=payload)
with open(f'trades-{backtest_id}.csv', 'w', newline='') as file:
    file.write(response.text)

### Export Insights

    file.write(response.text)

### Export Logs
# Download the logs of the backtest as a text file
