# # 3) Use it in your views/services
# # Replace direct imports with the factory:


# # in your recharge flow (views/services)
# from recharge.services.provider_factory import get_recharge_client

# client = get_recharge_client()

# # Mobile info
# info = client.mobile_info(mobile="9005464564")

# # Plans
# plans = client.recharge_plan(operator_code="AT", circle_code="23")

# # Recharge
# res = client.mobile_recharge(
#     txnid="AT12334304",
#     number="8918901273",
#     amount=10,
#     operator_code="JO",
#     circle_code="23",
# )

# # Status
# stat = client.status(txnid="AT12334304")

# # =======================================================

# # 4) (Optional) Normalizers
# # If you need uniform success flags/ids across providers, add a tiny helper:

# # recharge/services/normalizers.py
# def norm_status(v: str) -> str:
#     v = (v or "").strip().upper()
#     if v in {"SUCCESS"}: return "SUCCESS"
#     if v in {"PENDING", "PROCESSING"}: return "PENDING"
#     if v in {"FAILED"}: return "FAILED"
#     return "ERROR"

# def extract_ids(resp: dict) -> dict:
#     return {
#         "order_id": resp.get("orderId"),
#         "provider_txn_id": resp.get("RefId") or resp.get("optId"),
#         "client_txn_id": resp.get("TxnId") or resp.get("txnid"),
#     }
# # That’s it. Flip RECHARGE_PROVIDER in settings and your flow uses the other provider without touching business logic.
# # If your A1TopupAPI uses slightly different method names, tell me and I’ll stub a thin wrapper so it matches the
# # RechargeProvider Protocol exactly.
