ការប្រើប្រាស់កម្មវិធីជួយដំឡើង (guided setup wizard)

Ultimate Multisite 2.10.0 បានបន្ថែមកម្មវិធីជួយដំឡើង PayPal ដែលមាននៅក្នុងការកំណត់ Payment gateway។ បន្ទាប់ពីអ្នកបើកដំណើរការ PayPal រួច សូមប្រើកម្មវិធីជួយដំឡើងនៅលើ Ultimate Multisite > Settings > Payments ដើម្បីជ្រើសរើសរបៀបដែលអ្នកចង់ភ្ជាប់ gateway និងបញ្ជាក់ថាព័ត៌មានណាខ្លះដែលនៅតែត្រូវការមុនពេលរក្សាទុក។

កម្មវិធីជួយដំឡើងនេះគាំទ្រផ្លូវនៃការកំណត់ពីរ៖

• ការបញ្ចូលព័ត៌មានសម្ងាត់ដោយដៃ (Manual credential entry): ប្រើផ្លូវនេះនៅពេលអ្នកមានព័ត៌មាន API credentials របស់ PayPal រួចហើយ, នៅពេលដែលមិនមានការตั้งค่า OAuth សម្រាប់គណនីរបស់អ្នក, ឬនៅពេលដែលអ្នកចូលចិត្តចម្លងព័ត៌មានសម្ងាត់ពី PayPal ដោយខ្លួនឯង។ សូមបញ្ចូល API Username, API Password, និង API Signature ទៅក្នុងវាល PayPal បន្ទាប់មករក្សាទុកការកំណត់នៃការទូទាត់។
• ច្រករបាំងការភ្ជាប់ OAuth (OAuth connection gate): ប្រើផ្លូវនេះតែនៅពេលដែលជម្រើស OAuth មាននៅក្នុងការដំឡើងរបស់អ្នក ហើយត្រូវបានបើកដំណើរការ។ wizard នឹងបង្ហាញពីលំហូរ OAuth ដែលស្ថិតនៅពីក្រោយ feature flag, ដូច្នេះបណ្តាញដែលគ្មាន flag នោះនៅតែអាចប្រើវាលបញ្ចូលព័ត៌មានសម្ងាត់ដោយដៃបាន។

ប្រសិនបើអ្នកមិនឃើញជម្រើស OAuth នៅក្នុង wizard សូមបំពេញដំណើរការការបញ្ចូលព័ត៌មានសម្ងាត់ដោយដៃខាងក្រោម។ gateway នេះដំណើរការជាមួយ API credentials របស់ PayPal Business ដូចកំណែ Ultimate Multisite 2.x កន្លងមកដែរ។

ការទទួលបាន API credentials របស់ PayPal

នៅពេលដែលអ្នកបានបើកដំណើរការ PayPal ជា payment gateway អ្នកនឹងត្រូវបំពេញវាលសម្រាប់ Username របស់ PayPal API, Password របស់ PayPal API និង Signature របស់ PayPal API។

អ្នកអាចទទួលបានព័ត៌មាននេះដោយចូលទៅក្នុងគណនី Live ឬ Sandbox របស់អ្នក។

(សូមចងចាំថា អ្នកអាចប្រើ sandbox mode ដើម្បីសាកល្បងការទូទាត់ និងមើលថាតើ gateway ត្រូវបានตั้งค่าត្រឹមត្រូវឬអត់។ គ្រាន់តែបិទបើកផ្នែកដែលពាក់ព័ន្ធប៉ុណ្ណោះ)
