How can I create a document with horizontal page orientation using google doc api

Question

How can I create a document with horizontal page orientation (landscape) using google doc api (in python if possible)

Answer 1

This one was hard. For future generations:

body = {
    'title': 'Doc1'
}

doc = service.documents() \
    .create(body=body).execute()

file_id = doc.get('documentId')
requests =[
    {'updateDocumentStyle':{
        "documentStyle":{
            'pageSize':{
                  "height": {
                        'magnitude': 8.27,
                        'unit': 'PT'
                    },
                  "width": {
                        'magnitude': 11.69,
                        'unit': 'PT'
                    }
                }},
        "fields": 'pageSize'
        
    }}]
result = service.documents().batchUpdate(
    documentId=file_id, body={'requests': requests}).execute()
