Changelog

Updates to the Modulus Labs API suite, newest first. Covers QR, Webhooks, Onboarding, Terminal Gateway, Transaction Reporting, and Ecom.

June 15, 2026

Ecom Payment Links (Sandbox). Public management endpoints at /ecom/v1/payment-links to create, list, retrieve, update, and cancel hosted payment links. Auth is X-API-Key with payment_links.* permissions and partner/merchant/branch scoping. Link types are ONE_TIME and MULTI_USE; list pagination uses cursor/next_cursor, date_from, date_to, comma-separated status, and page_size up to 200. Create requires an Idempotency-Key. See the Ecom introduction and the API reference.

Aligned the QR ping endpoint with the request/response conventions used across the suite, so health checks behave consistently.

Transaction Reporting (Sandbox). A unified REST API for querying transaction history across QR and card-present in one consistent response format. Filter by merchant, branch, status, payment method, card brand, and date range; sort by date, amount, or last update; paginate with cursors. API keys are entity-scoped. See the introduction, the Quickstart, and the API reference.
