The transactions endpoint is your money ledger: one row per movement on your balance, newest first. It is the endpoint to reconcile against — a failed purchase and the refund that made you whole are two rows carrying the same order_id. Authentication required. Send your key as Authorization: Bearer csb_pub_.... Any valid key works; the trading flag is not needed.

A cancelled or failed order is always refunded, and the credit usually lands within seconds. You do not need to poll this endpoint to find out whether a refund happened — the order itself carries a refund object. Use /v1/transactions when you want the full money trail: bookkeeping, an internal statement, or an end-of-day reconciliation.

Reconciling a day

Walk the ledger with the cursor and sum by type — purchases and refunds net out against the orders you know:

import requests

HEADERS = {"Authorization": "Bearer csb_pub_..."}
cursor, totals = None, {}

while True:
    r = requests.get(
        "https://csboard.com/v1/transactions",
        params={"limit": 100, "start_unix_time": 1752451200, "cursor": cursor},
        headers=HEADERS,
    ).json()

    for tx in r["data"]:
        totals[tx["type"]] = round(totals.get(tx["type"], 0) + tx["amount_usd"], 2)

    cursor = r["meta"]["next_cursor"]
    if not cursor:
        break

print(totals)  # {'purchase': -524.89, 'refund': 65.09, ...}

Error codes
