# Respond to a dispute

> Accept or challenge a dispute using the respondToDispute GraphQL mutation, with options to provide supporting evidence.

**What is it?** The `respondToDispute` mutation accepts or challenges a dispute assigned to your organization. You have two options:

1. **Accept the dispute** - Acknowledge the dispute's validity and accept the chargeback
2. **Challenge the dispute** - Contest the dispute by providing supporting evidence

<Tip type="when to use">
  **When to Use**

  <ul>
    <li>A customer has disputed a transaction with their card issuer.</li>
    <li>You need to accept liability or challenge a dispute with evidence.</li>
    <li>You want to respond to a chargeback within the required timeframe.</li>
  </ul>
</Tip>

<Callout icon="clapperboard-play" color="#6938EF" type="scenario">
  **Scenario**

  A customer disputes a transaction at Maple Street Coffee, one of Clearpath Payments' acceptors. Clearpath Payments decides whether to accept the dispute or challenge it with evidence that the transaction was valid.
</Callout>

### Implementation rules

1. The dispute must be assigned to your organization before you can respond
2. When accepting a dispute, only the `disputeId` is required
3. When challenging a dispute, both the `disputeId` and at least one `attachmentId` are required
4. Attachment IDs are obtained by first uploading [evidence files](/acquiring/disputes/upload-evidence)
5. Responses must be submitted before the dispute's expiration date

The same mutation is used for both accepting and challenging a dispute, with different input parameters:

```graphql lines expandable theme={null}
mutation RespondToDispute($input: RespondToDisputeInput!) {
  respondToDispute(input: $input) {
    dispute {
      id
    }
    errors {
      ... on AttachmentsRequiredError {
        message
      }
      ... on ExpirationDateExceededError {
        expirationDate
        message
      }
      ... on InvalidAssignmentError {
        currentAssignment
        message
        validAssignments
      }
    }
  }
}
```
