README

Official PHP client for the Reloop API.

Before you send

1. API key — create one in your Reloop account
2. Verified domain — add and verify a sending domain; use it in the from address

Full API reference: reloop.sh/docs

Install

composer require reloop/reloop-email

Quick start

<?php

require 'vendor/autoload.php';

use Reloop\Exceptions\ReloopApiException;
use Reloop\Exceptions\ReloopValidationException;
use Reloop\Reloop;

$reloop = Reloop::client('rl_your_api_key_here');

try {
    $result = $reloop->mail->send([
        'from' => 'Reloop <[e-mail]>',
        'to' => '[e-mail]',
        'subject' => 'Welcome to Reloop',
        'html' => '<p>Thanks for signing up.</p>',
        'text' => 'Thanks for signing up.',
    ]);
    echo $result['messageId'] . ' ' . $result['id'] . PHP_EOL;
} catch (ReloopValidationException $e) {
    fwrite(STDERR, 'invalid request (' . $e->field . '): ' . $e->getMessage() . PHP_EOL);
} catch (ReloopApiException $e) {
    fwrite(STDERR, 'API error ' . $e->status . ': ' . $e->getMessage() . PHP_EOL);
}

Services

$reloop->apiKey;    // create, list, get, update, delete, rotate, enable, disable
$reloop->mail;      // send
$reloop->domain;    // create, list, get, update, delete, verify
$reloop->contacts;  // CRUD + ->properties, ->groups, ->channels
$reloop->webhook;   // CRUD, pause/enable/disable, trigger, deliveries + verify
$reloop->inbox;     // ->mailboxes, ->messages, ->threads

Errors

Kind	Type	When
Bad client args	ReloopValidationException	Invalid params — no HTTP call
HTTP / network	ReloopApiException	Non-2xx response or transport failure
Webhook HMAC	WebhookSignatureException	Local signature verification failed

Idiomatic PHP exceptions — aligned with the Java SDK and the Node/Python Result / Go (T, error) contracts.

Webhook verification

use Reloop\Services\WebhookVerify;

$event = WebhookVerify::constructEvent($payload, $signature, $secret, 300);
// or $reloop->webhook->verify([...])
