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
// 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;

$email = new Mail();
$email->setFrom("test@example.com", "Example User");
$email->setSubject("Sending with Twilio SendGrid is Fun");
$email->addTo("test@example.com", "Example User");
$email->addContent("text/plain", "and easy to do anywhere, even with PHP");
$email->addContent(
    "text/html", "<strong>and easy to do anywhere, even with PHP</strong>"
);

$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 to your emails. Because there is no official Box SDK for PHP, this example requires firebase/php-jwt to generate a JSON Web Token assertion. Before using this code, you should set up a JWT application on Box. For more information about authenticating with JWT, see this page.

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 after making any changes to your app’s JWT scopes.

<?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',
    'kid' => $boxConfig->boxAppSettings->appAuth->publicKeyID
);
$claims = array(
    'iss' => $boxConfig->boxAppSettings->clientID,

$privateKey = openssl_get_privatekey(
    $boxConfig->boxAppSettings->appAuth->privateKey,
    $boxConfig->boxAppSettings->appAuth->passphrase

Attaching a File from S3

You can attach a file from Amazon S3 storage to your emails. In addition to sendgrid-php, this requires the AWS SDK for PHP. Please follow the Getting Started tutorial at Amazon if you haven’t set up your AWS SDK installation yet.

<?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(
        "text/html", "<strong>See attached file from S3.</strong>"
    );

    $attachment = new \SendGrid\Mail\Attachment();
    $attachment->setContent($attachmentContent);
    $attachment->setType($attachmentContentType);
    $attachment->setFilename($attachmentFilename);
    $attachment->setDisposition("attachment");
    $attachment->setContentId($attachmentFilename); //Only used if disposition is set to inline
    $email->addAttachment($attachment);
    $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";
    }
} catch (S3Exception $e) {

Set Region

The SendGrid object can also be used to set the region to "eu", which will send the request to https://api.eu.sendgrid.com/. By default, it is set to https://api.sendgrid.com/, e.g.

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

$sendgrid = new \SendGrid(getenv('SENDGRID_API_KEY'));
$sendgrid->setDataResidency("eu");

OR

$sendgrid->setDataResidency("global");

Send an Email With Twilio Email (Pilot)

1. Obtain a Free Twilio Account

Sign up for a free Twilio account here.

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 or obtain your Account SID and Auth Token here.

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

Linux/Mac

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:

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

Windows

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

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):

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

$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.
