Contoh kod API SMS: curl, Node.js, Python, PHP, Go

Lihat sebagai Markdown Spesifikasi OpenAPI

Setiap contoh adalah program lengkap yang hanya menggunakan pustaka standard bahasanya (Node.js 18+ untuk fetch, Python 3, PHP dengan sambungan curl, Go 1.20+). Tetapkan BULKSMSAPI_KEY dalam persekitaran terlebih dahulu.
