```

--------------------------------

### Initializing SparkPost with Environment Variable API Key

Source: https://github.com/sparkpost/python-sparkpost/blob/master/README.rst

Initializes the SparkPost client. This method automatically uses the API key set in the `SPARKPOST_API_KEY` environment variable, which is the recommended approach for security and flexibility.

```python
from sparkpost import SparkPost
sp = SparkPost() # uses environment variable
```

--------------------------------

### Running Tox for Comprehensive Testing

Source: https://github.com/sparkpost/python-sparkpost/blob/master/CONTRIBUTING.md

```Shell
make test
```

--------------------------------

### Initializing SparkPost with Direct API Key

Source: https://github.com/sparkpost/python-sparkpost/blob/master/README.rst

Initializes the SparkPost client by directly passing the API key as a string argument. This method is an alternative to using environment variables, suitable for cases where direct key injection is preferred.

```python
from sparkpost import SparkPost
sp = SparkPost('YOUR API KEY')
```

--------------------------------

### Adding Requests Dependencies for Google Cloud

Source: https://github.com/sparkpost/python-sparkpost/blob/master/README.rst

requests-toolbelt
```

--------------------------------

### Sending a Test Transmission with SparkPost Python

Source: https://github.com/sparkpost/python-sparkpost/blob/master/README.rst

Demonstrates how to send a test email (transmission) using the SparkPost Python client. It initializes the client, then calls the `transmissions.send` method with recipient, content, and sender details, utilizing the sandbox environment for testing. The response object contains details about the transmission, including accepted and rejected recipients.

```python
from sparkpost import SparkPost

sp = SparkPost()

response = sp.transmissions.send(
    use_sandbox=True,
    recipients=['someone@somedomain.com'],
    html='<p>Hello world</p>',
    from_email='test@sparkpostbox.com',
    subject='Hello from python-sparkpost'
)

print(response)
# outputs {u'total_accepted_recipients': 1, u'id': u'47960765679942446', u'total_rejected_recipients': 0}
```

--------------------------------

### Initializing SparkPost for EU/Enterprise Accounts

Source: https://github.com/sparkpost/python-sparkpost/blob/master/README.rst

Initializes the SparkPost client for EU or Enterprise accounts by specifying both the API key and the custom API host URL. This is necessary for connecting to non-default SparkPost API endpoints, such as `https://api.eu.sparkpost.com`.

```python
from sparkpost import SparkPost
sp = SparkPost('YOUR API KEY', 'https://api.eu.sparkpost.com')
```

```python
SPARKPOST_API_KEY = 'API_KEY'
SPARKPOST_BASE_URI = 'api.sparkpost.com'
EMAIL_BACKEND = 'sparkpost.django.email_backend.SparkPostEmailBackend'
```

--------------------------------
