Python3 google spreadsheet api batchUpdate Json formatting - json

Question

I want to use google spreadsheet api batchUpdate to update different values with the same request.
In the documentation examples they use a dict to store the Json request but I need to set the same attribute (insertDimension) multiple times.
Here Google expected request
{
"requests": [
{
"insertDimension": {
"range": {
"sheetId": sheetId,
"dimension": "COLUMNS",
"startIndex": 2,
"endIndex": 4
},
"inheritBefore": true
}
},
{
"insertDimension": {
"range": {
"sheetId": sheetId,
"dimension": "ROWS",
"startIndex": 0,
"endIndex": 3
},
"inheritBefore": false
}
},
],
}
I tried using json.dumps
mydata = json.dumps('''
"requests": [{{"updateDimensionProperties": {"range": {"sheetId": 0,"dimension": "ROWS","startIndex": 0
"endIndex": 50
},
"properties": {
"pixelSize": 10
},
"fields": "pixelSize"
}
}
} ] ''')
but I receive this error message
"Invalid JSON payload received. Unknown name "": Root element must be a message."

Answer 1

Your request is invalid because it never says what kind of request it is: the insertDimension request. The correct form is
{
"requests": [
{
"insertDimension": {
# required fields at https://developers.google.com/sheets/api/reference/rest/v4/spreadsheets/request#InsertDimensionRequest
}
},
{
"insertDimension": {
# required fields at https://developers.google.com/sheets/api/reference/rest/v4/spreadsheets/request#InsertDimensionRequest
}
}]
}
By the way, one of the fields is inheritFromBefore, not inheritBefore
