# MNO Web Opt-In Nigeria

This document describes MNO Web Opt-In for NI.

### User Detection & Subscription in Nigeria <a href="#user_detection_subscription_in_nigeria" id="user_detection_subscription_in_nigeria"></a>

To subscribe a user in Nigeria, for *Direct Carrier Billing*, we must perform two separate steps.

1. Redirect the user to the **MSISDN Detection platform** which will return to us ( *if successful* ) the Network and the User ID.
2. Call the [**Subscribe method** ](/mno-web-opt-in/mno-web-opt-in-nigeria/subscribing-the-user-to-the-service.md)on the API providing the UserID and the ServiceID.

### Requesting the UserID <a href="#requesting_the_userid" id="requesting_the_userid"></a>

To request the UserID, you should have the following information ready:

| Parameter         | Required? | Description                                                                                         |
| ----------------- | --------- | --------------------------------------------------------------------------------------------------- |
| Return URL        | Yes       | Your **FULL** URL, including the `http://... .` User will be sent back to this url upon completion. |
| MTN Product ID    | Yes       | Required for detecting MTN customers.                                                               |
| Your Reference ID | No        | Your own reference ID.                                                                              |

**Flow**: Redirect the user to the Lookup URL. Once the lookup is performed, user will be sent back to your *Return URL.*&#x20;

***Example***

```html
https://<hostname>/lookup/ng/?return=<RETURN_URL>&ad_id=<MTN_PRODUCT_ID>&ref_id=<YOUR_REFERENCE>
```

The user will return to the given Return URL with the following **(GET)** parameters appended.

| Attribute | Example                | Description                                                                                        |
| --------- | ---------------------- | -------------------------------------------------------------------------------------------------- |
| hostname  | hostname.mobivate.com  | Mobivate's content hostname.                                                                       |
| status    | success/failed         | Describing the status of the lookup.                                                               |
| userid    | abcd4321\_-$           | Returned only if status==success! An ASCII value unique to this subscriber, instead of the MSISDN. |
| network   | mtnng / etisalatng     | Returned only if status==success! Network name for the subscriber                                  |
| message   | failed to detect user! | Returned only if status==failed! Error description                                                 |

***Examples***

On Successful detection user will return to your domain:

```http
http://www.yourdomain.com/nigeria-user-detection?status=success&userid=$abcd1234$&network=etisalatngp
```

On failure, the user will return to your domain while also containing a message:

```http
http://www.yourdomain.com/nigeria-user-detection?status=failed&message=Failed+to+detect+UserID.
```

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://wiki.mobivate.com/mno-web-opt-in/mno-web-opt-in-nigeria.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
