Gunakan endpoint ini untuk menunjukkan kepada pelanggan secara tepat apa yang akan mereka bayarkan saat meningkatkan atau menurunkan langganan mereka, meningkatkan transparansi dan mengurangi permintaan dukungan.

​
Kasus Penggunaan

  • Konfirmasi checkout: Tampilkan biaya prorata sebelum pelanggan mengonfirmasi perubahan paket
  • Kalkulator harga: Bangun kalkulator upgrade/downgrade dalam aplikasi Anda
  • Layanan mandiri pelanggan: Biarkan pelanggan menjelajahi opsi paket dengan harga yang akurat
  • Validasi diskon: Pratinjau bagaimana kode diskon bertingkat memengaruhi harga perubahan paket
Anda dapat menyertakan discount_codes (sebuah array hingga 20 kode, diterapkan secara berurutan) dalam permintaan pratinjau untuk melihat bagaimana diskon bertingkat memengaruhi biaya langsung dan harga paket baru sebelum melakukan perubahan. Field tunggal discount_code sudah tidak digunakan lagi tetapi masih didukung untuk kompatibilitas mundur; kami merekomendasikan discount_codes ke depannya.
