# RNTZ Migration
source: https://developer.mastercard.com/mastercard-merchant-presented-qr/documentation/server-apis/rntz-migration/index.md

Mastercard has introduced the Regional Network Transit Zone (RNTZ) to provide a faster and more secure connection to MPQR APIs. The following MPQR APIs are now available through RNTZ:

* [Payment](https://developer.mastercard.com/mastercard-merchant-presented-qr/documentation/server-apis/api-reference/payment-api/index.md)
* [Retrieval](https://developer.mastercard.com/mastercard-merchant-presented-qr/documentation/server-apis/api-reference/retrieval-api/index.md)

If you use any of these APIs, refer to the **Mastercard Merchant Presented QR RNTZ Migration Playbook** for instructions on migrating to the new RNTZ endpoints.
