# Webhook notification

Receive a webhook event when a bounty with an external reward is completed.

If you set a Bounty Webhook URL, Nexus sends you a webhook event notification whenever a creator completes a bounty that includes an external reward. The notification carries information on the reward.

Set your Bounty Webhook URL in your [Publisher Dashboard Settings](https://nexus.gg/publisher/dashboard/settings).

See [Webhooks](/additional-features/webhooks/) for detailed information on Nexus webhooks.

## Bounty reward notifications

A bounty reward notification has an `eventType` of `Bounty` and an `eventAction` of `BountyReward`. Its event data looks like this:

```json
{ 
    "attributionGroupId": "B8b84wld-ohveWtgQPJsS", 
    "attributionGroupName": "Great Game",
    "creatorId": "9jd7RBR_B2BZ0uWO3_lgv",
    "bountyId": "tzPlV9PeX9Tsxg158pZ47", 
    "bountyName": "Refer 5 Players", 
    "bountyProgressId": "4a3C8DLDjPToZ_BMRrYXx", 
    "playerId": "55d57cffaa074cc6b8d332f5d77661f2", 
    "bountyRewards": [
        {
            "id": "prYjeQugJG1n8qFCjW2rM", 
            "name": "In Game Title", 
            "amount": 1, 
            "externalId": "dalfjkAsdlgJkdal", 
            "creatorRewardId": "PDKczbm3bmNFZWcrelC5N"
        }
    ]  
}

```

`playerId` is the unique identifier you mapped to this creator when they linked with your Referral Program. If the notification omits `playerId`, this creator has not yet linked their Nexus account with your referral group. See [Generating codes for your program](/creator-code-api/program-management/adding-codes-to-your-program/) and [Linking to an existing Nexus](/creator-code-api/program-management/adding-codes-to-your-program/#linking-to-an-existing-nexus) to resolve this.

Each bounty reward includes the `externalId` you provided, which should map to the reward in your system.

Once you process a reward, [mark it complete](/additional-features/bounties/bounty-rewards/mark-reward-complete/) with its `creatorRewardId`.
