List an org's custom repository-property definitions

See what custom repository properties an org has defined — the schema, not any repo’s actual values.

Call

list_custom_properties_schema { "org": "<org>" }

Result

[
  { "propertyName": "team", "valueType": "single_select", "required": false },
  { "propertyName": "cost-center", "valueType": "string", "required": true }
]

required defaults to false if the org’s schema doesn’t specify it.

Next step

To see what values a specific repo currently has set for these properties, use get-repo-custom-properties.md. To set values across one or more repos, use set-repo-custom-properties.md — GitHub validates any propertyName you set against this org-level schema, so check it here first if a write unexpectedly fails.
