  description: "The Appealable Issues API lets you retrieve a list of a claimant’s appealable issues and any chains of preceding issues. Appealable issues are issues from claims about which VA has made a decision that may be eligible for appeal. Not all appealable issues are guaranteed to be eligible for appeal; for example, claimants may have another appeal in progress for an issue.\n\nTo check the status of all decision reviews and appeals for a specified individual, use the [Appeals Status API](https://developer.va.gov/explore/api/appeals-status/docs).\n\nTo file an appeal or decision review, use one of these APIs: \n* [Higher-Level Reviews API](https://developer.va.gov/explore/api/higher-level-reviews/docs)\n* [Notice of Disagreements API](https://developer.va.gov/explore/api/notice-of-disagreements/docs)\n* [Supplemental Claims API](https://developer.va.gov/explore/api/supplemental-claims/docs)\n\n## Technical overview\nThe Appealable Issues API pulls data from Caseflow, a case management system. It provides decision review and appeal data that can be used for submitting a Higher Level Review, Notice of Disagreement, or Supplemental Claim.\n\n### Authorization and Access\nThe authentication model for the Appealable Issues API uses OAuth 2.0/OpenID Connect. The following authorization models are supported:\n* [Authorization code flow](https://developer.va.gov/explore/api/appealable-issues/authorization-code)\n* [Client Credentials Grant (CCG)](https://developer.va.gov/explore/api/appealable-issues/client-credentials)\n\n**Important:** To get production access using client credentials grant, you must either work for VA or have specific VA agreements in place. If you have questions, [contact us](https://developer.va.gov/support/contact-us).\n\n### Test data\n\nOur sandbox environment is populated with [Veteran test data](https://github.com/department-of-veterans-affairs/vets-api-clients/blob/master/test_accounts/appealable_issues_test_accounts.md) that can be used to test various response scenarios. This sandbox data contains no PII or PHI, but mimics real Veteran account information.\n"
