# Disputes API reference

Learn about possible errors, and the different defense reasons and document type codes that can be returned using the Disputes API.

[View source](/risk-management/disputes-api/disputes-api-reference.md)

You can use the Defend Disputes API, or Disputes API in short, to automate the dispute handling process so that you can respond to disputes or chargebacks as soon as they are initiated. The [Disputes API](https://docs.adyen.com/api-explorer/Disputes/latest/overview) lets you retrieve defense reasons, supply and delete defense documents, and accept or defend disputes.

For an overview of the process and to learn more about how the API works, see the [Disputes API overview](/risk-management/disputes-api).

## Requirements

Before you begin, take into account the following requirements and limitations.

| **Setup steps**                                                | Before you begin, make sure that you:- Understand the general [dispute flow](/risk-management/understanding-disputes/dispute-process-and-flow/).
- Review the [chargeback guidelines](/risk-management/chargeback-guidelines) for specific card schemes and other payment methods that you use.
- Know the scenarios when Adyen [automatically handles disputes](/risk-management/manage-disputes#adyen-auto-defense-disputes) on your behalf. |

## Possible errors

If a [Disputes API](https://docs.adyen.com/api-explorer/Disputes/latest/overview) request fails, the response contains `success: false` and an `errorMessage` with more information about the error. The following table shows which error messages can be returned, and for which API request you can get the error.

## Retrieving defense reasons and documents

When you make a [/retrieveApplicableDefenseReasons](https://docs.adyen.com/api-explorer/Disputes/latest/post/retrieveApplicableDefenseReasons) request for a specific dispute, the `defenseReasons` object in the response contains:

* The [defense reason codes](#dispute-defense-reason-code) that are specified by the scheme regulations, and if the defense material for that reason code has already been supplied. Use these codes to find more information about the dispute, for example why it was raised.
* The corresponding [defense document type codes](#dispute-defense-document-type-code) for each defense reason code, if those document types are required, and if the documents are already supplied. Use these codes to understand which documents you can or have to provide to defend the dispute.

For example, the response could look like this:

## Defense document type codes

You can use defense document type codes to understand which documents you can or have to provide to defend a dispute with a specific [defense reason code](#dispute-defense-reason-code).

The `defenseReasons` object in the [/retrieveApplicableDefenseReasons](https://docs.adyen.com/api-explorer/Disputes/latest/post/retrieveApplicableDefenseReasons) response contains the applicable document type codes in the `defenseDocumentTypeCode` field. The response also indicates if those document types are required or optional, and if the documents are already available.

When you defend the dispute, you can only use the defense document type codes that are returned for the defense reason code.

You can add a generalized defense document type. Contact our [Support Team](https://ca-test.adyen.com/ca/ca/contactUs/support.shtml?form=other) to enable this document type. When enabled, you can supply a generic defense document for all schemes and set the `defenseDocumentTypeCode` to **AlternativeDefenseMaterial**.
