What the API is used for

🛒 E-shops

Order confirmation, shipping notice, tracking code. Customers know immediately, without waiting for an e-mail.

🧾 Invoicing systems

Due-date reminders, payment confirmation, a link to the invoice.

🔐 Verification codes

One-time codes (2FA), registration confirmation, login alerts.

⚙️ Custom systems

Monitoring, outages, internal alerts, booking systems. Anything that can send an HTTP request.
