# Multi-Level Referrals

Fuul supports up to **4 levels** of referral attribution, allowing you to reward not just the direct referrer, but also the affiliates who brought them into the program.

## How it works

| Level       | Who                             | Example                                                                     |
| ----------- | ------------------------------- | --------------------------------------------------------------------------- |
| **Level 1** | Direct referrer (the affiliate) | Alice refers Bob                                                            |
| **Level 2** | Referrer's referrer             | Carol referred Alice, who referred Bob                                      |
| **Level 3** | Third level up the chain        | Dave referred Carol, who referred Alice, who referred Bob                   |
| **Level 4** | Fourth level up the chain       | Eve referred Dave, who referred Carol, who referred Alice, who referred Bob |

When Bob converts, all four levels can receive a payout — each with its own amount or percentage, configured in the incentive rules.

## Per-tier multi-level amounts

When using audiences (tiers), each tier can define its own multi-level payout amounts independently. For example:

* **Standard tier**: Level 1 = 5%, Level 2 = 2%
* **VIP tier**: Level 1 = 10%, Level 2 = 5%, Level 3 = 2%, Level 4 = 1%

This lets you reward higher-performing affiliates with better rates at every level of their referral chain, not just at the top level.

## Viewing multi-level data

The [Affiliate Dashboard](/developer-guide/affiliate-dashboard.md) provides multi-level stats that distinguish between referral levels:

| Level                                                | Description                                            |
| ---------------------------------------------------- | ------------------------------------------------------ |
| **Level 1 (referred\_volume)**                       | Volume from users directly referred by the affiliate   |
| **Level 2 + Level 3 + Level 4 (multilevel\_volume)** | Volume from second, third, and fourth-degree referrals |
| **Total (total\_volume)**                            | Combined Level 1 + Level 2 + Level 3 + Level 4 volume  |

Affiliates can also view their full referral tree to understand how their network generates value.

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

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.fuul.xyz/core-concepts/referrals/multilevel-referrals.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

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.
