Installation

Requirements

• PHP 7.4
• An API Key from MailerLite
• PSR-7 and PSR-18 based HTTP adapter

Setup

composer require mailerlite/mailerlite-php

If you get an error saying “Could not find resource using any discovery strategy.” it means that all the discovery strategies have failed. Most likely, your project is missing the message factories and/or a PRS-7 implementation. To resolve this you may run

$ composer require php-http/curl-client guzzlehttp/psr7 php-http/message
