This SDK currently supports the following versions of CloudEvents:


Install the SDK using Composer:

$ composer require cloudevents/sdk-php

Create a CloudEvent

use CloudEvents\V1\CloudEvent;
use CloudEvents\V1\CloudEventImmutable;

// Immutable CloudEvent
$immutableEvent = new CloudEventImmutable(
    ['example' => 'first-event'],

// Mutable CloudEvent
$mutableEvent = new CloudEvent(
    ['example' => 'first-event'],

// Create immutable from mutable or via versa
$event = CloudEventImmutable::createFromInterface($mutableEvent);
$event = CloudEvent::createFromInterface($immutableEvent);

Serialize/Deserialize a CloudEvent

use CloudEvents\Serializers\JsonDeserializer;
use CloudEvents\Serializers\JsonSerializer;

// JSON serialization
$payload = JsonSerializer::create()->serializeStructured($event);
$payload = JsonSerializer::create()->serializeBatch($events);

// JSON deserialization
$event = JsonDeserializer::create()->deserializeStructured($payload);
$events = JsonDeserializer::create()->deserializeBatch($payload);

Marshal/Unmarshal a CloudEvent

use CloudEvents\Http\Marshaller;
use CloudEvents\Http\Unmarshaller;

// Marshal HTTP request
$request = Marshaller::createJsonMarshaller()->marshalStructuredRequest($event);
$request = Marshaller::createJsonMarshaller()->marshalBinaryRequest($event);
$request = Marshaller::createJsonMarshaller()->marshalBatchRequest($events);

// Marshal HTTP response
$request = Marshaller::createJsonMarshaller()->marshalStructuredResponse($event);
$request = Marshaller::createJsonMarshaller()->marshalBinaryResponse($event);
$request = Marshaller::createJsonMarshaller()->marshalBatchResponse($events);

// Unmarshal HTTP message
$events = Unmarshaller::createJsonUnmarshaller()->unmarshal($message);
