How to connect to the App Store Connect API using Python3

You will need the requests and authlib packages. Just run :

$ pip install requests authlib

Then you need to generate an API Key from the App Store Connect portal (https://developer.apple.com/documentation/appstoreconnectapi/creating_api_keys_for_app_store_connect_api).

In the Python code below, replace the values of KEY_ID, ISSUER_ID and PATH_TO_KEY with your own.

You can change the URL of the request you want to make with the URL variable.

Finally, if you have some query parameters to pass in, use the params parameter of requests.get() (or requests.post()).

appstoreconnect-api.py

import requests, time, json
from authlib.jose import jwt

KEY_ID = "XXXXXXXXXX"
ISSUER_ID = "XXXXXX-XXXXXXX-XXXXXX-XXXXXXX"
EXPIRATION_TIME = int(round(time.time() + (20.0 * 60.0))) # 20 minutes timestamp
PATH_TO_KEY = 'path/to/your/key.p8'
with open(PATH_TO_KEY, 'r') as f:
    PRIVATE_KEY = f.read()

header = {
    "alg": "ES256",
    "kid": KEY_ID,
    "typ": "JWT"
}

payload = {
    "iss": ISSUER_ID,
    "exp": EXPIRATION_TIME,
    "aud": "appstoreconnect-v1"
}

# Create the JWT
token = jwt.encode(header, payload, PRIVATE_KEY)

# API Request
JWT = 'Bearer ' + token.decode()
URL = 'https://api.appstoreconnect.apple.com/v1/users'
HEAD = {'Authorization': JWT}

r = requests.get(URL, params={'limit': 200}, headers=HEAD)

# Write the response in a pretty printed JSON file
with open('output.json', 'w') as out:
    out.write(json.dumps(r.json(), indent=4))

Where to find "path_to_key" ?
Anyone please reply fast is possible!!!

Thankyou in Advanced

@tanuj2207 You can get it from app store key section.

getting this error
JWT = 'Bearer ' + token.decode()
AttributeError: 'str' object has no attribute 'decode'

anyone ran into this error in the past ?

Thank you! Apple also seems to require "bid" (bundle id) param for JWT payload now - at least it kept giving me 401 until I added it. Here's how their current payload example looks like:

{
  "iss": "57246542-96fe-1a63e053-0824d011072a",
  "iat": 1623085200,
  "exp": 1623086400,
  "aud": "appstoreconnect-v1",
  "bid": "com.example.testbundleid2021"
}

Hi @alex-childish,

where did you get "bid"?

In app settings: https://support.appsflyer.com/hc/en-us/articles/360013555718-Finding-the-Apple-bundle-ID

I believe you can also get it via API:
