Membuat metadata Yoast SEO untuk kursus dan pelajaran MasterStudy LMS menggunakan ChatGPT, dengan Gato GraphQL untuk WordPress

Kita dapat menggunakan ChatGPT untuk membuat dan memperbarui metadata SEO secara otomatis untuk kursus dan pelajaran MasterStudy LMS, serta menyimpan metadata tersebut di Yoast SEO, semuanya dengan satu query Gato GraphQL.

Dalam demo ini, kita menggunakan GraphQL untuk:

Mengambil data kursus atau pelajaran dari MasterStudy LMS
Memanggil ChatGPT untuk menghasilkan metadata SEO berdasarkan data kursus atau pelajaran tersebut
Memperbarui metadata Yoast SEO untuk kursus atau pelajaran tersebut

Kita harus menyediakan variabel-variabel berikut:

courseOrLessonId: ID kursus atau pelajaran MasterStudy LMS yang akan diperbarui
openAIAPIKey: Kunci API untuk OpenAI API

Anda juga harus mengaktifkan akses data untuk Custom Post Types yang diperlukan: stm-courses dan stm-lessons.

Berikut adalah query GraphQL-nya:

query GetCourseOrLessonData($courseOrLessonId: ID!) {
  courseOrLesson: customPost(by: { id: $courseOrLessonId }, customPostTypes: ["stm-courses", "stm-lessons"]) {
    id
    ...on CustomPost {
      title
        @export(as: "title")
      content
        @export(as: "content")
    }
    ...WithMetaData
  }
}
 
query GenerateCourseSEOWithChatGPT(
  $openAIAPIKey: String!
  $systemMessage: String! = "You are an SEO specialist"
  $promptTemplate: String! = """
