Error Handling Best Practices

try:
    response = client.post("/v1/transfers/payouts", data)
    return response.json()
except APIError as e:
    if e.type == "rate_limit_error":
        time.sleep(60)
        return retry_request()
    elif e.type == "validation_error":
        log_validation_error(e.message)
        return None
    else:
        raise
