AlertyFast
AlertyFast is a lightweight API platform for sending WhatsApp notifications from your own systems. Developers, SaaS products, and e-commerce stores connect with a simple POST request and push transactional messages to users in real time.
You can run on AlertyFast shared infrastructure to launch quickly, or plug in your own WhatsApp instance when you want full control over the number and delivery path. The same API works either way, so you can switch modes as your needs grow without rewriting integrations.
A dashboard tracks usage and delivery confirmations, and a downloadable WordPress plugin adds WooCommerce order and payment alerts with minimal setup.
