Parcel Wing PHP

Official PHP SDK for the Parcel Wing API.

composer require parcelwing/parcelwing-php

Send an email

<?php

require __DIR__ . '/vendor/autoload.php';

use ParcelWing\ParcelWing;
use ParcelWing\Exceptions\ParcelWingException;

$parcelwing = new ParcelWing($_ENV['PARCELWING_API_KEY']);

try {
    $emails = $parcelwing->emails->send([
        'from' => 'Acme <onboarding@example.com>',
        'to' => 'delivered@example.com',
        'subject' => 'Hello from Parcel Wing',
        'html' => '<strong>It works!</strong>',
    ]);

    print_r($emails);
} catch (ParcelWingException $error) {
    echo $error->getMessage() . PHP_EOL;
}

emails->send() returns an array of queued email objects. If to contains multiple recipients, Parcel Wing queues one email per recipient.

Client options

$parcelwing = new ParcelWing(
    apiKey: $_ENV['PARCELWING_API_KEY'],
    baseUrl: 'https://parcelwing.com',
    timeoutMs: 30000,
    headers: [
        'X-Request-Source' => 'my-app',
    ],
);

baseUrl is useful for local testing or preview deployments.

Email API

$parcelwing->emails->send([
    'from' => 'Sender <sender@example.com>',
    'to' => ['alice@example.com', 'bob@example.com'],
    'subject' => 'Quarterly update',
    'text' => 'Plain-text fallback',
    'html' => '<p>HTML body</p>',
    'reply_to' => 'support@example.com',
    'tags' => [
        'campaign' => 'q1-update',
    ],
]);

Templates

Use either template_id or template_alias, not both.

$parcelwing->emails->send([
    'from' => 'Acme <onboarding@example.com>',
    'to' => 'new-user@example.com',
    'template_alias' => 'welcome',
    'template_params' => [
        'first_name' => 'Ada',
        'workspace_name' => 'Acme',
    ],
]);

Contacts

$contact = $parcelwing->contacts->create([
    'email' => 'ada@example.com',
    'first_name' => 'Ada',
    'last_name' => 'Lovelace',
    'attributes' => [
        'plan' => 'flight',
    ],
]);

$contacts = $parcelwing->contacts->list([
    'limit' => 25,
    'status' => 'active',
]);

$updated = $parcelwing->contacts->update($contact['id'], [
    'first_name' => 'Augusta Ada',
]);

$parcelwing->contacts->delete($contact['id']);

Batch create contacts by passing an array of contact payloads:

$result = $parcelwing->contacts->create([
    ['email' => 'alice@example.com'],
    ['email' => 'bob@example.com'],
]);

Segments

$segment = $parcelwing->segments->create([
    'name' => 'Flight customers',
    'filter_criteria' => [
        'version' => 1,
        'match' => 'all',
        'conditions' => [[
            'field' => 'attribute',
            'attribute_key' => 'plan',
            'operator' => 'equals',
            'value' => 'flight',
        ]],
    ],
]);

$segments = $parcelwing->segments->list(['include_counts' => true]);

Topics

$topic = $parcelwing->topics->create([
    'name' => 'Product updates',
    'description' => 'News and product announcements.',
    'default_subscription' => 'opt_out',
    'visibility' => 'public',
]);

Automations

$event = $parcelwing->automations->track([
    'event_name' => 'user.signup',
    'contact_id' => 'contact_id_here',
    'payload' => [
        'plan' => 'launch',
    ],
]);

Error handling

Failed API calls throw ParcelWing\Exceptions\ParcelWingException.

try {
    $parcelwing->emails->send([
        'from' => 'bad',
        'to' => 'not-an-email',
    ]);
} catch (ParcelWingException $error) {
    echo $error->status;     // HTTP status, or 0 for network errors
    echo $error->type;       // validation_error, authentication_error, api_error, etc.
    echo $error->errorCode ?? ''; // Parcel Wing error code when available
    print_r($error->details);
}
