# 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.

{% hint style="info" %}
Both modes use the same operational screen for bulk changes: [Contact Upload](/netmera-user-guide/targeting/contact-upload.md).
{% endhint %}

### Quickstart

{% stepper %}
{% step %}

#### Get your IYS credentials

Have these ready from the IYS portal:

* **Brand Code**
* **IYS Code**
  {% endstep %}

{% step %}

#### Install and configure the integration

In the Netmera panel:

1. Go to **Integrations**.
2. Find **İleti Yönetim Sistemi** under **Data Security**.
3. Click **Install**.
4. Enter **Brand Code** and **IYS Code**.
5. Enable **IYS Integrator** only if you will use Integrator Mode.
   {% endstep %}

{% step %}

#### Authorize Netmera in the IYS portal

In IYS, open **İş Ortaklığı (Partnerships)**.

Select **Netmera**.

Enable the needed permissions (Email/SMS/Call).

If you use **Integrator Mode**, also enable the integrator permission and make sure **Mutabakat Yönetimi** is on.
{% endstep %}

{% step %}

#### Validate consent flow with Contact Upload

Go to `Targeting > Contact Upload`.

Choose one of these actions:

* **Pull Consents from IYS**: refresh Netmera from IYS.
* **Push Consents to IYS**: send file consent to IYS.
  {% endstep %}
  {% endstepper %}

{% hint style="warning" %}
If email and SMS have different consent statuses, upload them in separate files.
{% endhint %}
