# Grant Contact Consent

Notifications is Norbix's unified Email + Push + SMS messaging system — one template engine and data-binding context across all three channels, for both transactional sends and high-volume campaigns. Handles the contact consent. `POST /{version}/notifications/contacts/{contactId}/marketing-state/{channel}/consent`

{% hint style="info" %}
Full request/response reference will appear here once this method is added to the API spec.
{% endhint %}

This method is on the **Hub** surface (`norbix.hub.notifications`) — call it from admin tooling or IaC.

{% hint style="info" %}
These examples assume the SDK is installed and your credentials are set as environment variables — each client reads them automatically, so the constructors below take no arguments. See [Install a Norbix SDK](/sdks-and-cli/install.md).
