# IYS Permissions

IYS (İleti Yönetim Sistemi) is Turkey’s central consent registry for email and SMS. IYS Permissions lets you decide how consent data flows between Netmera and IYS.

### Choose an integration mode

This choice sets the “source of truth” for consent.

#### IYS Sync Mode

Use this when **IYS already contains the definitive consent records**.

Key behavior:

* Netmera can **pull** consent from IYS.
* Netmera can **update** consent in IYS for **existing** IYS users.
* Netmera **cannot create** new consent records in IYS.

#### IYS Integrator Mode

Use this when **Netmera collects consent** (web/app/call center) and you need to **push** it to IYS.

Key behavior:

* Netmera can **create** and **update** consent records in IYS.
* Netmera acts as the master system for consent state.

Both modes use the same operational screen for bulk changes: [Contact Upload](https://user.netmera.com/netmera-user-guide/targeting/contact-upload).
