Jukto (যুক্ত) Python SDK 🇧🇩

A sync and native async Python SDK for Bangladesh's SMS and courier APIs, created by Mehedi H Faysal.

Early access: 0.1.0a1. APIs may change before a stable release. Offline tests verify implementation behavior, not live provider compatibility. SSLCOMMERZ is experimental and has not completed authorized merchant lifecycle verification.

What it does

Jukto provides synchronous clients for Steadfast, Pathao, RedX, GreenWeb, AlphaSMS and BulkSMSBD. Shared interfaces and typed result models reduce adapter code; changing providers still requires their credentials, geography, required fields and a review of supported capabilities. The SDK includes py.typed; raw provider data remains dynamically typed.

Known HTTP/application errors become JuktoError subclasses. Malformed or unrecognized responses raise UnexpectedProviderResponseError; undocumented codes retain generic classifications. An accepted submission is not proof of shipment or SMS delivery. Ambiguous outcomes require reconciliation before retry.

Experimental SSLCOMMERZ hosted BDT payments are included in this alpha; see the payment guide and verification gaps. Standalone bKash and Nagad remain planned. Native asyncio clients are included for SMS, logistics and hosted payments; see the async guide for lifecycle, cancellation and FastAPI usage. Existing sync clients still block.

See the provider contract and capability matrix for evidence dates and unresolved contracts. Offline tests are implementation regressions, not live provider certification.

Install and try it offline

python -m pip install jukto==0.1.0a1

The installation command works after the alpha is published. Python 3.9+ is required; CI covers 3.9–3.15. Explicitly pin the alpha version when evaluating it.

This standalone example works with the installed package and cannot send an SMS:

import httpx
from jukto import AlphaSMSClient

def reply(request: httpx.Request) -> httpx.Response:
    return httpx.Response(200, json={"error": 0, "data": {"request_id": 123}})

with httpx.Client(transport=httpx.MockTransport(reply)) as http_client:
    with AlphaSMSClient(api_key="synthetic-example-key", http_client=http_client) as provider:
        result = provider.submit_sms("01700000000", "Synthetic offline message")
    assert not http_client.is_closed  # Injected client stays caller-owned.

print(result.status.value)  # accepted means submitted, not delivered.

For source-only framework examples and contributor checks:

git clone https://github.com/jukto-sdk/jukto-python.git
cd jukto-python
python -m venv .venv
# Activate this environment using your shell, then:
python -m pip install -e '.[dev,examples]'
python -m examples.offline_quickstart
python -m pytest tests/test_documentation_examples.py --no-cov

The quickstart uses HTTPX MockTransport and synthetic data; it cannot send an SMS. See Django and FastAPI examples for configuration, client lifetime, dependency injection and offline request tests. Production calls require your own provider account and independent contract verification.

Safety and lifecycle

Clients reuse an owned HTTP client and support with/close(). Injected clients are borrowed and remain caller-owned. HTTPS and verified TLS are the defaults; redirects are refused. Explicit allow_insecure_http=True permits legacy HTTP and exposes credentials/content in cleartext; the quickstarts do not enable it.

Debug logs contain allowlisted metadata only. response_body, result raw, and recipient evidence can contain secrets or personal data; do not log them. No operation has a generic retry or automatic provider failover. See error and reconciliation guidance.
