# Sharing Rewards with Referred Users

Affiliates can automatically share a portion of their rewards with the users they refer. This creates a mutual incentive: affiliates earn more by bringing in users, and referred users get rewarded for completing actions.

## How it works

When an affiliate creates a referral code with a **rebate rate**, that percentage of their payout is automatically transferred to the referred user at payout time.

|                        | Rate    |
| ---------------------- | ------- |
| Affiliate commission   | 20%     |
| Rebate rate            | 5%      |
| **Affiliate receives** | **15%** |
| **Referred user gets** | **5%**  |

The rebate rate is set on the referral code and **locked at the moment a user accepts it**. If the rate changes later, existing referrer relationships keep their original locked rate — only new relationships use the updated rate.

{% hint style="info" %}
The rebate is taken from the affiliate's share, not added on top. The total reward budget for the project remains the same.
{% endhint %}

## Configuration

Set the rebate rate when generating a referral code. The maximum allowed rebate rate is **20%** — values above this are automatically capped.

{% hint style="info" %}
See [Affiliate Links & Codes](/developer-guide/creating-affiliate-links-or-codes.md) for the full affiliate code API, including the `rebateRate` parameter and the Updating Rebate Rates section.
{% endhint %}

## Supported payout types

Double side rewards apply to **variable payout terms only** — programs where rewards are calculated as a percentage of volume or revenue. Fixed rewards and pool distributions do not support rebates.

## Use cases

* **VIP affiliate programs** — top affiliates attract high-value users by passing on part of their commission
* **Two-sided marketplaces** — both the referrer and the new user need an incentive to participate
* **Referral competitions** — affiliates compete by offering the best rebate to maximize their referred volume

## 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/double-side-rewards.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.
