# Changelog

> Latest updates and improvements to Modulus Labs APIs

## Overview

Track the latest changes, improvements, and updates to the Modulus Labs API suite. This changelog covers all APIs: QR, Onboarding, Webhooks, Terminal Gateway, Transaction Reporting, and Ecom.

<Note>
  All APIs are currently in sandbox mode. Production releases will be announced here.
</Note>

## Week of June 15, 2026

### New features

* **Ecom API (Sandbox).** A REST API for creating and managing hosted payment links. Generate a shareable checkout URL, accept `one_time` or `multi_use` payments, update or cancel active links, and reconcile results through payment webhooks. API keys are entity-scoped, and mutating requests use idempotency keys for safe retries. See the [Ecom introduction](/docs/ecom/introduction) and the [API reference](/api-reference/ecom/create-payment-link) to get started.

## Week of May 4, 2026

### Improvements

* **Removed unsupported card brands.** `JCB` and `UNIONPAY` are no longer listed as supported card brands across the documentation, leaving the set of brands that the platform actually processes.
* **Aligned the ping endpoint.** The QR API `ping` endpoint now matches the request, response, and documentation conventions used by the other APIs, so health checks behave consistently across the suite.

## Week of April 27, 2026

### New features

* **Transaction Reporting API (Sandbox).** A unified, REST-based API for querying transaction history across all payment methods (QR and card-present) using a single, consistent response format. Filter by merchant, branch, status, payment method, card brand, and date range; sort by date, amount, or last update; and paginate across large datasets with cursor-based pagination. API keys are entity-scoped, so partners, merchants, and branches each see only the data they're authorized for. See the [Transaction Reporting introduction](/docs/transaction-reporting/introduction) and the [Quickstart](/docs/transaction-reporting/quickstart) to get started, or jump to the [API reference](/api-reference/transaction-reporting/list-transactions).
