# Mark a reward complete

Mark a fulfilled bounty reward complete and optionally attach a reference ID visible to the creator.

After you fulfill a reward's requirements, mark it complete. You can optionally attach a `referenceId`, which is shown to the creator so they can reference it if they need to contact you about the reward.

A reward you are about to complete looks like this:

```json
{
  "id": "kCxr7lst7Ghk8n1o6DKEF",
  "name": "In game Title",
  "externalId": "dalfjkAsdlgJkdal",
  "playerId": "55d57cffaa074cc6b8d332f5d77661f2",
  "rewardCompleted": false
}
```

In this example, the creator is entitled to an "In game Title" as a bounty reward. The `externalId` is a unique identifier to map the reward to what the creator will actually receive in your system. Once the reward has been fulfilled, you can mark it complete by using the complete-reward API:

<ApiMethod method="POST" path="/complete-reward/{rewardId}" />
<LinkCard title="View full reference" description="Parameters, responses, and status codes." href="/api/bounties/operations/completereward/" />

```bash
curl -X 'POST' \
  'https://api.nexus.gg/v1/bounties/complete-reward/kCxr7lst7Ghk8n1o6DKEF' \
  -H 'accept: */*' \
  -H 'Content-Type: application/json' \
  -H 'X-SHARED-SECRET: nexus_sk_your_key_here' \
  -d '{
  "referenceId": "55d57cffaa074cc6b8d332f5d77661f2"
}'
```

The status should be `200 OK` with a JSON response body that looks something like this:

```json
{
  "id": "kCxr7lst7Ghk8n1o6DKEF",
  "name": "In game Title",
  "externalId": "dalfjkAsdlgJkdal",
  "rewardCompleted": true,
  "rewardReferenceId": "55d57cffaa074cc6b8d332f5d77661f2" 
}
```
