GetTripOptions পদ্ধতির তুলনায়, GetBulkTripOptions পদ্ধতির নিম্নলিখিত সুবিধা রয়েছে:
- Google ক্যাশের আরও দক্ষ জনসংখ্যার জন্য অনুমতি দেয়, কম অনুরোধ ব্যবহার করে এবং অপারেটরদের থেকে আপস্ট্রিম APIগুলির সাথে আরও ভালভাবে সারিবদ্ধ করে যা অংশীদাররা নিজেরাই ডেটা অর্জন করতে ব্যবহার করতে পারে।
- উপলভ্য ট্রিপের পূর্বনির্ধারিত সেট সহ অংশীদারদের বিশদ ভ্রমণসূচী পরিদর্শন ছাড়াই তাদের ডেটা সরবরাহ করা সহজ করে তোলে।
- আরও পরিশীলিত অংশীদারদের জন্য, এখনও Google রাউটিং ইঞ্জিন দ্বারা উত্পাদিত অংশীদার ইনভেনটরি এবং ভ্রমণপথের মিল সর্বাধিক করতে তাদের পরিচিত ভ্রমণপথের একটি তালিকা প্রদান করে, এইভাবে যতটা সম্ভব যাত্রাপথে অংশীদারের মূল্য দেখায়৷
- ভবিষ্যতে Google রাউটিং ইঞ্জিনকে আরও ভালভাবে মেলে পার্টনার ইনভেন্টরির সাথে সামঞ্জস্য করার জন্য, Google এখনও পরিবেশন করছে না এমন ভ্রমণপথগুলিকে প্রবেশ করার অনুমতি দেয়৷

সাধারণ পরিস্থিতি

কম প্রযুক্তিগতভাবে পরিশীলিত অংশীদারদের জন্য, শুধুমাত্র একটি
market_dateপ্রদান করে। এই অংশীদাররা তাদের আপস্ট্রিম ডেটাতে একটিmarket_dateভিত্তিক প্রশ্ন ব্যবহার করতে পারে এবং আমাদের ডেটা বিন্যাসে ম্যাপ করা সমস্ত ফলাফল ফেরত দিতে পারে। Google শুধুমাত্র প্রত্যাশিত ভ্রমণপথে ফলাফল ফিল্টার করতে পারে।আরও প্রযুক্তিগতভাবে পরিশীলিত অংশীদারদের জন্য, একটি
market_dateএবংknown_itinerariesউভয়ই প্রদান করে। অংশীদার অভ্যন্তরীণ ডাটাবেসে একটি বিশদ সন্ধান করতে পারে যাতে প্রত্যাশিত ভ্রমণপথের সঠিক মূল্য নির্ধারণ করা যায়। সমস্ত অনুরোধকৃতknown_itinerariesব্যবহারকারীদের দেখানো হবে, যাতে অংশীদাররা তাদের মূল্য এবং বুকিং লিঙ্ক দেখায় এমন ভ্রমণপথের সংখ্যা সর্বাধিক করতে পারে। Google-কে তাদের নিজস্ব (প্রচারিত) ইনভেন্টরির সাথে আরও ভালভাবে মেলে সাহায্য করার জন্য অংশীদারদের কাছে এখনও অতিরিক্ত ভ্রমণপথ ফেরত দেওয়ার বিকল্প রয়েছে৷
প্রতিবেদনে ত্রুটি
প্রতিটি ট্রিপের জন্য পৃথকভাবে ত্রুটি রিপোর্ট করা উচিত। অতএব, পছন্দের প্রতিক্রিয়া হল একটি BulkTripOptionsResult (HTTP 200), bulk_trip_options_result.itinerary_responses[i].trip_options_error এ প্রতি-ট্রিপে ত্রুটি নির্দেশ করে। সম্পূর্ণ অনুরোধটি অপ্রত্যাশিতভাবে ব্যর্থ হলে, BulkTripOptionsErrorType.INTERNAL_ERROR (HTTP 500) এর সাথে bulk_trip_options_error ব্যবহার করুন।

মন্তব্য
MarketDate.departure_date একটি ক্যালেন্ডার দিন নির্দিষ্ট করে। অপারেটর এপিআইগুলিকে আরও ভালভাবে মেলাতে, এটি মূলে টাইমজোন ব্যবহার করবে৷ যাইহোক, SegmentKey GetTripOptions সাথে সামঞ্জস্যের জন্য UTC ব্যবহার করে বোর্ডিং এবং আগমনের সময় নির্দিষ্ট করতে থাকবে।
