# Attachments

Here is an example of attaching a text file to your email, assuming that text file `my_file.txt` is located in the same directory. You can use the `addAttachments` method to add an array attachments.

```php
<?php
// Uncomment next line if you're not using a dependency loader (such as Composer)
// require_once '<PATH TO>/sendgrid-php.php';

use SendGrid\Mail\Mail;

$file_encoded = base64_encode(file_get_contents('my_file.txt'));
$email->addAttachment(
    $file_encoded,
    "application/text",
    "my_file.txt",
    "attachment"
);

$sendgrid = new \SendGrid(getenv('SENDGRID_API_KEY'));
try {
    $response = $sendgrid->send($email);
    print $response->statusCode() . "\n";
    print_r($response->headers());
    print $response->body() . "\n";
} catch (Exception $e) {
    echo 'Caught exception: '.  $e->getMessage(). "\n";
}
```

# Attaching a File from Box

You can attach a file from [Box](https://www.box.com) to your emails.
Because there is no official Box SDK for PHP, this example requires
[firebase/php-jwt](https://github.com/firebase/php-jwt) to generate a
[JSON Web Token](https://jwt.io) assertion. Before using this code, you should
set up a JWT application on [Box](https://developer.box.com/docs/setting-up-a-jwt-app).
For more information about authenticating with JWT, see
[this page](https://developer.box.com/docs/construct-jwt-claim-manually).

After completing the setup tutorial, you will want to make sure your app’s
configuration settings have at least the following options enabled:

**Application Access**
* Enterprise

**Application Scopes**
* Read all files and folders stored in Box
* Read and write all files and folders stored in Box
* Manage users

**Advanced Features**
* Perform Actions as Users

Remember to reauthorize your app
[here](https://app.box.com/master/settings/openbox) after making any changes to
your app’s JWT scopes.

```php
<?php
// This example assumes you're using Composer for both the sendgrid-php library and php-jwt.
require 'vendor/autoload.php';

use \Firebase\JWT\JWT;

$fileOwner = 'email@example.com'; // Replace with the email you use to sign in to Box
$filePath = '/path/to/file.txt'; // Replace with the path on Box to the file you will attach
// Replace with the path to your Box config file. Keep it in a secure location!
$boxConfig = json_decode(file_get_contents('/path/to/boxConfig.json'));

$path = explode('/', $filePath);
if (!empty($path[0])){
    // Adds a blank element to beginning of array in case $filePath does not have a preceding forward slash.
    array_unshift($path, '');
}

$header = array(
    'alg' => 'RS256',
    'typ' => 'JWT',

# Attaching a File from S3

You can attach a file from [Amazon S3 storage](https://aws.amazon.com/s3/) to your emails. In addition to sendgrid-php, this requires the [AWS SDK for PHP](https://aws.amazon.com/sdk-for-php/). Please follow the [Getting Started](https://docs.aws.amazon.com/sdk-for-php/v3/developer-guide/getting-started_index.html) tutorial at Amazon if you haven’t set up your AWS SDK installation yet.

```php
<?php
// This example assumes you're using Composer for both
// the sendgrid-php library and the AWS SDK for PHP.
require 'vendor/autoload.php';
use Aws\S3\S3Client;
use Aws\S3\Exception\S3Exception;
$bucket = '*** Your Bucket Name ***';
$keyname = '*** Your Object Key ***';
$s3 = new S3Client([
 'version' => 'latest',
 'region' => 'us-east-1' // This should match the region of your S3 bucket.
]);
try {
 // Get the object.
 // See https://docs.aws.amazon.com/AmazonS3/latest/dev/RetrieveObjSingleOpPHP.html
 $result = $s3->getObject([
 'Bucket' => $bucket,
 'Key' => $keyname
 ]);
 $keyExplode = explode('/',$keyname);
 $attachmentFilename = end($keyExplode);
 $attachmentContent = base64_encode($result['Body']);
 $attachmentContentType = $result['ContentType'];

$email = new \SendGrid\Mail\Mail();
 $email->setFrom("test@example.com", "Example User");
 $email->setSubject("Attaching a File from S3");
 $email->addTo("test@example.com", "Example User");
 $email->addContent("text/plain", "See attached file from S3.");
 $email->addContent(

    $attachment->setContent($attachmentContent);
    $attachment->setType($attachmentContentType);
    $attachment->setFilename($attachmentFilename);
    $attachment->setDisposition("attachment");
    $attachment->setContentId($attachmentFilename); //Only used if disposition is set to inline
    $email->addAttachment($attachment);

# Send an Email With Twilio Email (Pilot)

### 1. Obtain a Free Twilio Account

### 2. Set Up Your Environment Variables

The Twilio API allows for authentication using with either an API key/secret or your Account SID/Auth Token. You can create an API key [here](https://twil.io/get-api-key) or obtain your Account SID and Auth Token [here](https://twil.io/console).

Once you have those, follow the steps below based on your operating system.

#### Linux/Mac

```bash
echo "export TWILIO_API_KEY='YOUR_TWILIO_API_KEY'" > twilio.env
echo "export TWILIO_API_SECRET='YOUR_TWILIO_API_SECRET'" >> twilio.env

# or

echo "export TWILIO_ACCOUNT_SID='YOUR_TWILIO_ACCOUNT_SID'" > twilio.env
echo "export TWILIO_AUTH_TOKEN='YOUR_TWILIO_AUTH_TOKEN'" >> twilio.env
```

Then:

```bash
echo "twilio.env" >> .gitignore
source ./twilio.env
```

#### Windows

Temporarily set the environment variable (accessible only during the current CLI session):

```bash
set TWILIO_API_KEY=YOUR_TWILIO_API_KEY
set TWILIO_API_SECRET=YOUR_TWILIO_API_SECRET

: or

set TWILIO_ACCOUNT_SID=YOUR_TWILIO_ACCOUNT_SID
set TWILIO_AUTH_TOKEN=YOUR_TWILIO_AUTH_TOKEN
```

Or permanently set the environment variable (accessible in all subsequent CLI sessions):

```bash
setx TWILIO_API_KEY "YOUR_TWILIO_API_KEY"
setx TWILIO_API_SECRET "YOUR_TWILIO_API_SECRET"

: or

setx TWILIO_ACCOUNT_SID "YOUR_TWILIO_ACCOUNT_SID"
setx TWILIO_AUTH_TOKEN "YOUR_TWILIO_AUTH_TOKEN"
```

### 3. Initialize the Twilio Email Client

```php
$twilioEmail = new \TwilioEmail(\getenv('TWILIO_API_KEY'), \getenv('TWILIO_API_SECRET'));

// or

$twilioEmail = new \TwilioEmail(\getenv('TWILIO_ACCOUNT_SID'), \getenv('TWILIO_AUTH_TOKEN'));
```

This client has the same interface as the `SendGrid` client.

# Send an SMS Message

First, follow the above steps for creating a Twilio account and setting up environment variables with the proper credentials.

Then, install the Twilio Helper Library.

```bash
composer require twilio/sdk
```

Finally, send a message.

```php
<?php
$sid = \getenv('TWILIO_ACCOUNT_SID');
$token = \getenv('TWILIO_AUTH_TOKEN');

$client = new \Twilio\Rest\Client($sid, $token);
$message = $client->messages->create(
  '8881231234', // Text this number
  [
    'from' => '9991231234', // From a valid Twilio number
    'body' => 'Hello from Twilio!'
  ]
);
```

For more information, please visit the [Twilio SMS PHP documentation](https://www.twilio.com/docs/sms/quickstart/php).

<a name="domain-authentication"></a>
# How to Set up a Domain Authentication

You can find documentation for how to setup a domain authentication via the UI [here](https://sendgrid.com/docs/ui/account-and-settings/how-to-set-up-domain-authentication/) and via API [here](USAGE.md#sender-authentication).

Find more information about all of Twilio SendGrid's authentication related documentation [here](https://sendgrid.com/docs/ui/account-and-settings/).

<a name="email-stats"></a>
# How to View Email Statistics

You can find documentation for how to view your email statistics via the UI [here](https://app.sendgrid.com/statistics) and via API [here](USAGE.md#stats).

Alternatively, we can post events to a URL of your choice via our [Event Webhook](https://sendgrid.com/docs/for-developers/tracking-events/event/) about events that occur as Twilio SendGrid processes your email.

<a name="email-activity"></a>
# How to Use the Email Activity Feed API

In order to gain access to the Email Activity Feed API, you must [purchase](https://app.sendgrid.com/settings/billing/addons/email_activity) additional email activity history. To learn about Sendgrid's API to download information from the Email Activity feed, get started [here](https://sendgrid.com/docs/API_Reference/Web_API_v3/Tutorials/getting_started_email_activity_api.html).

<a name="heroku"></a>
# Deploying to Heroku

Use the button below to instantly setup your own Simple instance for sending email using SendGrid on Heroku.

<a name="GAE-instructions"></a>
# Google App Engine Installation

Google App Engine installations with Composer require the creation of file `php.ini` in the base folder(the same directory as the `app.yaml` file). You can read more about this file [here](https://cloud.google.com/appengine/docs/standard/php/config/php_ini).

The file `php.ini` should contain:

```ini
google_app_engine.enable_curl_lite = 1
```
