hexpay 0.0.1

Official Python SDK for the HexPay Merchant API (TON cryptocurrency payments).

HexPay Python SDK

Official Python client for the HexPay Merchant API — TON-blockchain cryptocurrency payments.

The client in hexpay/ is fully auto-generated from the OpenAPI spec at oapi/api.yaml. Do not edit it by hand — your changes will be overwritten on the next regeneration.

Installation

pip install "git+https://github.com/hexpay/hexpay-python.git"

Or pin to a release tag:

pip install "git+https://github.com/hexpay/hexpay-python.git@v0.0.1"

Quickstart

import os
import uuid

from hexpay import AuthenticatedClient
from hexpay.api.payments import create_payment
from hexpay.models import CreatePaymentRequest

client = AuthenticatedClient(
    base_url="https://api.hexpay.io",
    token=os.environ["HEXPAY_TOKEN"],
)

payment = create_payment.sync(
    client=client,
    body=CreatePaymentRequest(amount="100.00", currency="USD"),
    x_idempotency_key=str(uuid.uuid4()),
)

print(payment.id, payment.checkout_url)

Authentication

All endpoints require a JWT obtained from the HexPay merchant dashboard. Pass it as the token argument to AuthenticatedClient. Never hard-code tokens — load them from environment variables, a secrets manager, or your config layer.

Idempotency

Every POST request requires a UUID v4 X-Idempotency-Key. The SDK exposes it as the x_idempotency_key argument on every mutating operation.

Reuse the same key when retrying a failed request — the server returns the cached response from the first attempt instead of creating a duplicate payment. Generate a fresh key for each new logical operation.

See examples/idempotency_retry.py for a complete retry loop that gets this right.

Async

Every endpoint exposes both sync and asyncio entry points:

import asyncio
from hexpay.api.payments import list_payments

async def main():
    page = await list_payments.asyncio(client=client, limit=20)
    for p in page.payments:
        print(p.id, p.status)

asyncio.run(main())

Examples

Runnable scripts under examples/ — each is self-contained and reads HEXPAY_TOKEN (and optionally HEXPAY_BASE_URL) from the environment:

File	What it shows
create_payment_customer_choice.py	Customer-Choice mode — checkout picks the method
create_payment_preselected.py	Preselected USDT/TON — pending immediately
retrieve_payment.py	Fetch full payment details
poll_payment_status.py	Lightweight status polling loop
list_payments.py	Cursor-based pagination
cancel_payment.py	Cancel an active payment
list_payment_methods.py	Discover store-enabled coin/chain combos
error_handling.py	Pattern for inspecting structured errors
idempotency_retry.py	Safe retry loop preserving the idempotency key

Run them with:

make gen install                # generate client + install into .venv/
export HEXPAY_TOKEN="<your-jwt>"
.venv/bin/python examples/create_payment_customer_choice.py

Or activate the venv once and use plain python:

source .venv/bin/activate
python examples/create_payment_customer_choice.py

Regeneration

make gen      # rebuild hexpay/ from oapi/api.yaml — runs in Docker
make install  # editable install into a local venv
make lint     # ruff check

make gen builds a small image from gen.Dockerfile (based on python:3.12-slim with openapi-python-client preinstalled) and runs it against the spec — no host Python required. The generator version is pinned by OPENAPI_PYTHON_CLIENT_VERSION in the Dockerfile.

CI (.github/workflows/generate.yml) runs the same make gen on every push to a non-main branch and commits the regenerated client back to the branch.
