Panduan referensi XML ini memberikan konten referensi mendetail dan contoh kode untuk berbagai pesan, elemen, dan atribut yang tersedia untuk feed Ketersediaan, Tarif, dan Inventaris (ARI).
ARI adalah mode pengiriman harga yang mengontrol tarif, ketersediaan, dan inventaris per malam, serta memberikan batasan terkait bagaimana semua opsi tersebut dapat digabungkan. ARI juga
memberikan fleksibilitas untuk menyertakan pajak, biaya, dan promosi.
ARI mengikuti protokol standar OpenTravel Alliance (OTA) untuk beberapa
jenis pesan utama guna menentukan ketersediaan dan inventaris.
Harga berdasarkan LOS
Harga LOS-based memungkinkan Anda menentukan tarif per tanggal check-in dan lama menginap, bukan per tanggal menginap. Saat Anda menentukan elemen <StatusApplicationControl> untuk harga berdasarkan LOS, atribut @Start dan @End menandakan rentang tanggal check in yang diberlakukan tarif LOS.
Meskipun saat menggunakan harga berbasis LOS, tidak ada lagi tarif per malam, semua fitur ARI lainnya (inventaris, ketersediaan, aturan, promosi, dll.) masih dapat diterapkan pada tarif ini dan ditentukan pada tingkat per malam. Artinya, jika sistem Anda lebih selaras dengan sistem penetapan harga berbasis LOS, Anda masih dapat memanfaatkan set fitur ARI yang lengkap, selain efisiensi bandwidth yang diberikan dengan memanfaatkan ketersediaan setiap malam dan update batasan.
Untuk mengaktifkan harga berdasarkan LOS di akun Anda, hubungi TAM Anda atau
hubungi kami.
OTA_HotelRateAmountNotifRQ. Menentukan jumlah tarif jumlah tamu per tanggal atau berdasarkan LOS per produk (kombinasi jenis kamar dan paket tarif) untuk rentang tanggal tertentu.
OTA_HotelAvailNotifRQ. Menentukan ketersediaan dan batasan
berdasarkan jenis kamar dan paket tarif. Inventaris juga dapat diperbarui menggunakan pesan
ini, tetapi OTA_HotelInvCountNotifRQ lebih disarankan.
OTA_HotelInvCountNotifRQ. Menentukan inventaris kamar fisik atau jumlah kamar yang tersedia untuk dijual.
TaxFeeInfo. (Opsional) Menentukan pajak dan biaya per properti. Pesan
ini tidak diperlukan jika AmountAfterTax ditentukan dalam
pesan OTA_HotelRateAmountNotifRQ.
Promotions. (Opsional) Menentukan tarif promosi untuk pemesanan, masa inap, dan pengguna tertentu.
RateModifications. (Opsional) Menentukan aturan modifikasi tarif untuk pemesanan, lama menginap, dan pengguna tertentu.
ExtraGuestCharges. (Opsional) Menentukan bagaimana tarif
harus dikonfigurasi untuk anak-anak dan orang dewasa tambahan.
Setiap pesan berisi subkumpulan informasi yang digunakan Google untuk menghitung harga dan ketersediaan yang ditampilkan kepada pengguna saat mereka menelusuri properti Anda dengan tanggal check-in dan check-out serta jumlah tamu tertentu.

ARI also\nprovides flexibility to include taxes, fees, and promotions.\n\nARI follows the standard protocols of OpenTravel Alliance (OTA) for some of\nthe main message types for defining availability and inventory.\n\n### LOS-based pricing\n\n`LOS-based` pricing lets you to specify rates per check-in date and length of\nstay, rather than per stay date. When you specify a\n`\u003cStatusApplicationControl\u003e` element for LOS-based pricing, the `@Start` and\n`@End` attributes signifies a range of check-in dates for which the LOS rates\napply.\n\nAlthough when using LOS-based pricing there are no longer nightly rates, all\nother ARI features (inventory, availability, rules, promotions, etc.) can still\nbe applied to these rates and are specified at a nightly level. This means if\nyour systems more closely align with an LOS-based pricing system, you can still\ntake advantage of the rich ARI feature set, in addition to the bandwidth\nefficiency that is granted by making use of the nightly availability and\nrestriction updates.\n| **Key Point:** Each property in your account should use either LOS-based rates or per-date rates.\n\nTo enable LOS-based pricing on your account, contact your TAM or\n[contact us](https://support.google.com/hotelprices/gethelp).\n| **Key Point:** You must send the four message types (transaction, rate, inventory, and availability) before pricing is available. It is recommended that you the size of ARI messages specifically `\u003cOTA_HotelRateAmountNotifRQ\u003e` to 5MB with a limit of 400 files per second upload rate.\n\nARI uses the following request messages:\n\n- [`Transaction` (Property Data)](/hotels/hotel-prices/xml-reference/ari-property). Defines the type and package\n (rate plan) information.\n\n- [`OTA_HotelRateAmountNotifRQ`](/hotels/hotel-prices/xml-reference/ari-rate). Defines the per-date or LOS-based\n occupancy rate amounts per product (room type and rate plan combination) for\n specific date ranges.\n\n- [`OTA_HotelAvailNotifRQ`](/hotels/hotel-prices/xml-reference/ari-avail). Defines availability and restrictions\n based on room type and rate plans. Inventory can also be updated using this\n message, but `OTA_HotelInvCountNotifRQ` is preferred.\n\n- [`OTA_HotelInvCountNotifRQ`](/hotels/hotel-prices/xml-reference/ari-inv). Defines the physical room inventory or\n number of rooms available to be sold.\n\n- [`TaxFeeInfo`](/hotels/hotel-prices/xml-reference/ari-tax). (Optional) Defines per-property taxes and fees. This\n message isn't required if `AmountAfterTax` is specified in the\n `OTA_HotelRateAmountNotifRQ` message.\n\n- [`Promotions`](/hotels/hotel-prices/xml-reference/ari-promotions). (Optional) Defines promotional rates for\n certain bookings, stays, and users.\n\n- [`RateModifications`](/hotels/hotel-prices/xml-reference/ari-rate-modifications). (Optional) Defines rate\n modification rules for certain bookings, stays, and users.\n\n- [`ExtraGuestCharges`](/hotels/hotel-prices/xml-reference/ari-extra-guest-charges). (Optional) Defines how rates\n should be configured for children and additional adults.\n\nEach message contains a subset of information that Google uses to compute the\nprices and availability displayed to users when they search for your\nproperties with specific check-in and check-out dates and occupancy.\n| **Key Point:** ARI features is limited to the messages and elements described within this Inventory \\& Pricing (ARI) XML reference and the ARI guide. Any OTA message, element, or attribute not specifically documented here is not supported in our ARI implementation.\n|\n|\n| Also, other [Transaction message](/hotels/hotel-prices/xml-reference/transaction-messages) elements not covered in\n| this Inventory \\& Pricing (ARI) XML reference are not supported when\n| using the ARI feed type.\n| Google continues to update and improve the API. If you use additional pricing features in your system, notify your `Technology Account Manager(TAM)` so that it can be prioritized with those features or they will let you know if those features are planned for a release.\n\nARI XML Reference revision history\n----------------------------------\n\nThe following table lists documentation updates for feature changes only.\n\n| Date | Changes |\n|-------------------|----------------------------------------------------------------------------------------------------------------------------------------------------------------------------|\n| August 14, 2020 | Initial release. |\n| October 21, 2020 | Added the Promotions message type. |\n| November 17, 2020 | For Transaction (Property Data) messages, updated the [endpoint](../dev-guide/ari-overview#pushing-messages) and added the `action` attribute to PropertyDataSet elements. |\n| November 24, 2020 | For Transaction (Property Data) messages, added the `\u003cAllowablePackageIDs\u003e` and `\u003cAllowableRoomIDs\u003e` elements. |\n| February 4, 2021 | Added response messages. |\n| February 25, 2021 | Added `OTA_HotelInvCountNotifRQ`. |\n| October 21, 2020 | Added the Rate Modifications message type. |"]]
