PassKit Python gRPC SDK

Generated Python clients and message types for the PassKit gRPC API. Use the SDK to build integrations for membership and loyalty cards, coupons, event tickets, boarding passes, and the other PassKit services.

Requirements

• Python 3.9 or newer
• A PassKit account and API credentials for live API calls

Install

python -m pip install passkit-python-grpc-sdk

Pin a specific release when reproducible installs are important:

python -m pip install passkit-python-grpc-sdk==1.1.162

The package installs the compatible gRPC, Protocol Buffers, Google API annotations, and OpenAPI annotation runtimes automatically.

Use the SDK

Import the generated messages and service stubs for the PassKit product you want to use:

import grpc

from passkit.io.common.common_objects_pb2 import Id
from passkit.io.member.a_rpc_pb2_grpc import MembersStub

with open("certs/ca-chain.pem", "rb") as file:
    root_certificate = file.read()
with open("certs/key.pem", "rb") as file:
    private_key = file.read()
with open("certs/certificate.pem", "rb") as file:
    certificate_chain = file.read()

credentials = grpc.ssl_channel_credentials(
    root_certificates=root_certificate,
    private_key=private_key,
    certificate_chain=certificate_chain,
)
channel = grpc.secure_channel(
    "grpc.pub1.passkit.io:443",
    credentials,
)
members = MembersStub(channel)

program = members.getProgram(Id(id="YOUR_PROGRAM_ID"))
print(program)

For complete credential setup and runnable membership, coupon, event-ticket, and flight examples, see the PassKit Python quickstart.
