Usage ⌨️

Writing Data ✍️

Step 1: Create a Google Form 📝

Create a form with required fields.

Step 2: Set Response Destination 🎯

Choose a Google Sheet to save responses.

Step 3: Customize Sheet 📊

Rename sheet and columns (optional).

Step 4: Get Form Link 🔗

Press Send and copy the link.

Step 5: Create RetrosheetInterceptor 🔧

val retrosheetInterceptor = RetrosheetInterceptor.Builder()
    .setLogging(false)
    .addSheet("notes", "created_at", "title", "description")
    .addForm(ADD_NOTE_ENDPOINT, "Form Link")
    .build()

val okHttpClient = OkHttpClient.Builder()
    .addInterceptor(retrosheetInterceptor) // and attach the interceptor
    .build()

Step 6: Create API Interface 🌐

interface NotesApi {
    @Read("SELECT *") 
    @GET("notes")
    suspend fun getNotes(): List<Note>

    @Write
    @POST(ADD_NOTE_ENDPOINT)
    suspend fun addNote(@Body addNoteRequest: AddNoteRequest): AddNoteRequest
}

@Write is used for writing data and @Read: for reading data

Reading Data 📖

Step 7: Share Sheet 🔄

Open a sheet and copy its shareable link.

Step 8: Edit Link ✂️

Trim the link after the last '/'.

Step 9: Set Base URL 🔗

Use the trimmed link as baseUrl in Retrofit or OkHttp.

Done 👍
