# Subscribing the User to the Service

Once you have the UserID you can request a subscription to your service. For this you can use our NetworkSubscription API. The User ID is normally the MSISDN number associated with the subscription.

For subscribing a **MTN Customer** request:

```markup
GET: https://<hostname>/lookup/subscribe/mtnng/?userid={USERID}&keyword={PRODUCT_ID}
```

For subscribing an **Etisalat** Customer request:

```http
GET: https://<hostname>/lookup/subscribe/etisalatng/?userid={USERID}&keyword={PRODUCT_ID}
```

{% hint style="info" %}
The required parameters for the **Etisalat** Customer request are as follows:
