PHP SDK v4 release

We’ve released the PHP SDK v4 (getbrevo/brevo-php) with a type-safe client for the Brevo API: unified Brevo client, strongly typed request and response objects with PHPDoc annotations, PSR-18 HTTP client compatibility (Guzzle, Symfony HttpClient), automatic retries with exponential backoff, and structured error handling via BrevoApiException.

You can learn more on the dedicated guide here: https://developers.brevo.com/docs/api-clients/php

Install it using:

$composer require getbrevo/brevo-php

Guzzle is recommended as the HTTP client:

$composer require getbrevo/brevo-php guzzlehttp/guzzle

Key highlights:

  • Unified client via Brevo(apiKey: "...") — single entry point with namespaced service clients
  • Strongly typed request and response objects with full PHPDoc annotations
  • PSR-18 HTTP client support — use Guzzle, Symfony HttpClient, or any compatible client
  • Automatic retries with exponential backoff (configurable per client or per request)
  • Structured errors via BrevoApiException with getCode(), getBody(), and getMessage()
  • 33 service namespaces covering the entire Brevo API
