When to use this endpoint

Without wallet lookup	With wallet lookup
Guess whether funds arrived	Verify exact balance before creating charges
No visibility into wallet state	Check wallet status, currency, and creation date
Manual reconciliation in spreadsheets	Automated reconciliation — compare expected vs. actual
Hard-coded wallet UUIDs everywhere	Dynamic lookup by email or customer_id
Cannot build multi-currency dashboards	Query each currency wallet and aggregate for reporting

---

Reconciliation flow

Authentication

Requires Bearer token. See Authentication.

Query parameters

Field	Type	Required	Description
wallet_uuid	string (UUID)	At least one	Direct wallet lookup by UUID
email	string	At least one	Find wallet by associated email
customer_id	string	At least one	Find wallet by your internal customer ID

Flexible lookup

Provide at least one parameter. You can combine them to narrow results — for example, ?customer_id=cust_12345&currency=BRL finds the BRL wallet for that customer.

Complete example — daily reconciliation script

A practical script that checks wallet state and compares it against your expected records:

cURL

#!/bin/bash
# Daily wallet reconciliation — run via cron
TOKEN="$A55_API_TOKEN"
BASE="https://core-manager.a55.tech/api/v1/bank/wallet/"

WALLETS=("cust_12345" "cust_67890" "cust_24680")

for CUST_ID in "${WALLETS[@]}"; do
  RESPONSE=$(curl -s -G "$BASE" \
    -H "Authorization: Bearer $TOKEN" \
    --data-urlencode "customer_id=$CUST_ID")

  WALLET_UUID=$(echo "$RESPONSE" | jq -r '.wallet_uuid')
  CURRENCY=$(echo "$RESPONSE" | jq -r '.currency')

  if [ "$WALLET_UUID" = "null" ]; then
    echo "MISSING: No wallet for customer $CUST_ID"
  else
    echo "OK: $CUST_ID → $WALLET_UUID ($CURRENCY)"
  fi
done

Python

import requests
import os

token = os.environ["A55_API_TOKEN"]
base = "https://core-manager.a55.tech/api/v1/bank/wallet/"
headers = {"Authorization": f"Bearer {token}"}

expected_wallets = {

    "cust_67890": "MXN",
    "cust_24680": "BRL",
}

reconciliation = {"matched": 0, "missing": 0, "mismatch": 0}

for customer_id, expected_currency in expected_wallets.items():
    response = requests.get(
        base,
        params={"customer_id": customer_id},
        headers=headers,
    )

    if response.status_code == 404:
        print(f"MISSING: {customer_id} — no wallet found")

Tips

Cache wallet UUIDs

After the first lookup, cache the wallet_uuid in your database. Direct UUID lookups are faster than email or customer_id queries. Only fall back to email/customer_id lookup when the cached UUID returns a 404 (wallet was deleted and recreated).

Rate limits

Wallet lookups share the global rate limit of 100 requests/minute per token. For high-volume reconciliation, batch your lookups with a small delay between requests rather than firing all at once.

Don't poll for balance changes

Use webhooks to react to charge status changes in real-time. Reserve wallet lookups for scheduled reconciliation jobs, not as a substitute for event-driven architecture.

Create wallet →Set up a new wallet for a merchant and currency.Create charge →Process a payment on this wallet.List charges →Retrieve all charges for a wallet with filters and pagination.
