You can turn your API auth mode to be "API KEY" and call an AppSync mutation with http.

For example.

import requests
import json

APPSYNC_API_KEY = 'da2-xxxxxxxxxxxxx'
APPSYNC_API_ENDPOINT_URL = 'https://xxxxxxxxxxxxx.appsync-api.us-west-2.amazonaws.com/graphql'

headers = {
    'Content-Type': "application/graphql",
    'x-api-key': APPSYNC_API_KEY,
    'cache-control': "no-cache",
}

def execute_gql(query):
    payload_obj = {"query": query}
    payload = json.dumps(payload_obj)
    response = requests.request("POST", APPSYNC_API_ENDPOINT_URL, data=payload, headers=headers)
    return response

Imagine you have a model called Items and you can easily make query like below:

if __name__ == '__main__':
    print(execute_gql("query { listItems { items { id name } } }").json())

Simply replace the string with the mutation operation.
