Accessing AppSync GraphQL APIs from python

appsync.py

import json
import requests

from boto3.session import Session as AWSSession
from gql_py import Gql
from requests import Session
from requests_aws4auth import AWS4Auth

aws = AWSSession()
session = Session()

# Discover boto3 credentials, use them to manually sign appsync requests
credentials = aws.get_credentials().get_frozen_credentials()
# Create a `requests` compatible auth object
session.auth = AWS4Auth(
    credentials.access_key,
    credentials.secret_key,
    aws.region_name,
    'appsync',
    session_token=credentials.token,
)
session.headers = {
    'Accept': 'application/json',
    'Content-Type': 'application/json',
}

# Use the lovely gql library by @phalt
API_URL = 'https://xxxxxxxxxxxxxx.appsync-api.eu-west-1.amazonaws.com/graphql'
api = Gql(api=API_URL, session=session)


list_entries = '''
query {
  listEntries(limit: 10) {
    items {
      slug
    }
  }
}
'''


def main():
    entries = api.send(query=list_entries)
    print(entries.data)


if __name__ == '__main__':
    main()

Thanks! very helpful

To work with my appsync deployment I had to also pass in the session token from boto to AWS4Auth

session.auth = AWS4Auth(
    credentials.access_key,
    credentials.secret_key,
    aws.region_name,
    'appsync',
    session_token=credentials.token,
)

Thanks @mfogel, I've updated the gist with that feedback.
