Lookup Unused Schema Parts via the GraphQL API

You can find unused types, fields and values within you GraphQL API by using the Schemaversion.unusedSchema field.

The returned UnusedSchemaExplorer type will contain a list of types and their unused fields and values.

The SchemaVersion.unusedSchema(period:) argument specifies the period to look at in order to identify whether a schema part is unused. If the argument is omitted a period of the last 30 days is used.

Example: Retrieve a list of unused schema parts


query UnusedSchemaQuery(
  $organizationSlug: String!
  $projectSlug: String!
  $targetSlug: String!
  $period: DateRangeInput!
) {
  target(
    reference: {
      bySelector: {
        organizationSlug: $organizationSlug
        projectSlug: $projectSlug
        targetSlug: $targetSlug
      }
    }
  ) {

    latestValidSchemaVersion {

Lookup Deprecated Schema Parts via the GraphQL API

You can find deprecated types, fields and values within you GraphQL API by using the Schemaversion.deprecatedSchema field.

The returned DeprecatedSchemaExplorer type will contain a list of types and their unused fields and values.

The SchemaVersion.deprecatedSchema(period:) argument specifies the period to for attaching contextual schema usage data in order to determine while the deprecated field is still being used or can be removed safely. If the argument is omitted a period of the last 30 days is used.

Example: Retrieve a list of deprecated schema parts with statistics about usage


query DeprecatedSchemaQuery(
  $organizationSlug: String!
  $projectSlug: String!
  $targetSlug: String!
  $period: DateRangeInput!
) {
  target(
