mojowallet

Python SDK for MojoWallet — digital wallet operations, sessions, balance management, and financial ledger tools.

Installation

pip install mojowallet

Requirements: Python 3.10+ | Dependencies: requests, pyobjict

Quick Start

import mojowallet

client = mojowallet.Client("your-api-key", base_url="https://api.example.com")

wallet = client.Wallet.get(42)
wallet.add_funds(1000, "SC_REAL", source="CREDIT_CARD")
print(wallet.balance("SC_REAL"))

Each Client carries its own credentials, so one process can serve multiple tenants by holding one Client per group.

Since 2.4.0 the client keeps per-thread pooled keep-alive connections and splits timeouts: Client(..., connect_timeout=3, timeout=30) (connect / read, sent as timeout=(connect, read)). Connect-phase failures are retried exactly once for GET/DELETE and for POSTs whose payload carries a reference_id. Set the MOJOWALLET_DISABLE_POOL env var to revert to per-call requests, and pass on_request_metrics=callable to observe {method, path_prefix, status_code, elapsed_ms, retried, pooled} per request.

Since 2.5.0 a bet/game spend is one call — the server resolves the customer's wallet, checks funds and your cap against the same holdings it draws from, and returns the complete post-spend family snapshot:

data = client.Wallet.spend_by_customer(
    "cust-abc123", 10000, "SC", "bet-round-42", cap_units=25000)
data.replayed, data.split, data.balances

Retrying a committed reference_id returns the original result with replayed=True and moves no money. See Wallet Operations.

All responses support both dict-style (resp["id"]) and attribute-style (resp.id) access.

Core Concepts

Usage Examples

# Funds (wallet obtained via client.Wallet.get / get_by_customer)
wallet.add_funds(1000, "SC_REAL", source="CREDIT_CARD", category="deposited")
wallet.purchase(500, "SC_REAL", merchant="Coffee Shop")
wallet.cashout(800, "SC_REAL", reference_id="cashout-001")

# Sessions (context manager for safety)
with wallet.session("game-xyz", expires_in_seconds=3600) as session:
    session.withdraw(500, "SC_REAL", reference_id="bet-001")
    session.extend(1800)

# Balances
balance = wallet.balance("SC_REAL")
summary = wallet.balance_summary()

# Reserve flow
wallet.reserve(2500, "SC_REAL", "SC_HOLD", reference_id="payout-001")
wallet.confirm_reservation("payout-001")

# Lock/unlock
wallet.lock(reason="Chargeback")
wallet.unlock(reason="Investigation cleared")

Spending across a currency family

# Walk the SC family in priority order and debit across holdings as needed.
wallet.spend(750, root_code="SC", reference_id="game-bet-001", merchant="Casino")

Balance reads

balance_summary() returns balances grouped by root currency family (root_code), with per-currency totals exposed separately:

s = wallet.balance_summary()
s.balances.SC.available          # 200000
s.balances.SC.by_code.SC_REAL    # {quantity: 150000, formatted: "$1500.00"}
s.total_by_currency.SC_REAL      # per-currency rollup, unchanged from 2.2.x

For per-holding detail or a single family lookup:

holdings   = wallet.get_holdings(root_code="SC")
sc_balance = wallet.get_root_balance("SC")

⚠ Breaking change in 2.3.0: balance_summary().balances is now keyed by root_code (was currency_code). Callers reading s.balances["SC_REAL"] must switch to s.total_by_currency["SC_REAL"] or s.balances["SC"].by_code["SC_REAL"].

Error Handling

from mojowallet.exceptions import InsufficientBalanceError, SessionConflictError

try:
    wallet.cashout(10000, "SC_REAL", reference_id="cashout-002")
except InsufficientBalanceError as e:
    print(f"Not enough funds: {e.message}")
except SessionConflictError:
    print("Another session is already active")

Error codes

Wallet errors carry a numeric code (5000-block) and an HTTP status from the table below. The SDK raises a matching subclass whenever the response body includes a code in this range — the dispatch is authoritative regardless of HTTP status.

WalletInvariantError deliberately surfaces only a generic "please retry" message — never the server's diff text — so safety-critical balance-check failures don't leak internal state.

SpendCapExceededError (2.5.0) is not a subclass of InsufficientBalanceError — the wallet could afford the spend and the caller's own cap_units rejected it, so the two need different handling.
