Transactions API: The List cash accounts endpoint response now includes a primary boolean field indicating whether the cash account is the primary cash account for the Brex account. All APIs: Added new header X-Brex-Trace-Id for tracing; previous header X-Datadog-Trace-Id is still in use but X-Brex-Trace-Id is recommended as it is vendor-agnostic. Payments API: Added cancellation_reason to the Transfer response.
