Apple CloudKit server-to-server support for the requests Python library.

Project description

This project provides an authentication handler for Apple’s CloudKit server-to-server API for the requests Python library. In English, this means that this library lets you interact with CloudKit with Python in a server environment. It just has two dependencies–requests and python-ecdsa–and lets you skip all of the dull and boring cryptographic signing steps when authenticating with CloudKit on your own. While the underlying code is pretty straightforward, there was no correct code sample available online that described how to do this–but now there is!


requests-cloudkit is available for download through the Python Package Index (PyPi). You can install it right away using pip or easy_install.

pip install requests-cloudkit


requests-cloudkit provides an authentication handler that can be passed directly to the requests library to authenticate requests to the CloudKit API. Before working with the CloudKit server-to-server API, you’ll first need to follow Apple’s instructions to generate a certificate and a server-to-server key (see Accessing CloudKit Using a Server-to-Server Key).

Once you have these values, just plug them into a CloudKitAuth object, which you can use with requests to interface with CloudKit. E.g.:

>>> import requests
>>> from requests_cloudkit import CloudKitAuth
>>> auth = CloudKitAuth(key_id=YOUR_KEY_ID, key_file_name=YOUR_PRIVATE_KEY_PATH)
>>> requests.get("[version]/[container]/[environment]/public/zones/list", auth=auth)

Using Requests-CloudKit with RestMapper

requests-cloudkit can also be used with RestMapper to integrate directly with the CloudKit API.

>>> CloudKit = restmapper.RestMapper("[version]/[container]/[environment]/")

Instantiate a cloudkit instance using your CloudKit server-to-server key ID and provide the path to the private key file.

>>> cloudkit = CloudKit(auth=CloudKitAuth(key_id=YOUR_KEY_ID, key_file_name=YOUR_KEY_FILE))

Now, you can start making requests to the CloudKit API using a nice attribute syntax.

>>> response = cloudkit.public.zones.list()

The above will hit[version]/[container]/[environment]/public/zones/list.

If you want to pass in body data for a POST, provide a single argument to the call to the API, and specify “POST” as the first attribute (note: this argument expects a str value, so if you want to pass JSON, use json.dumps to encode it into a string). I.e.
