# List available metadata objects

`GET /object-metadata`

Returns all available objects for the specified metadata context.

Each object includes basic metadata such as object name, label, category,
custom field support indicator, and a link to retrieve the full object schema.

This list operation is supported only for Data Query(DQ) and Object Query(OQ) contexts.

For Data Source Export and Aggregate Query API contexts, this operation is not supported. To retrieve metadata for Data Source Export(DSE) or
Aggregate Query API(AQuA), use [Retrieve metadata object schema](https://developer.zuora.com/v1-api-reference/api/metadata/retrievemetadataobjectschema) with the required context.

## Query parameters

- `context` 'DQ' | 'OQ', required

## Headers

- `Accept-Encoding` string
- `Content-Encoding` string
- `Zuora-Track-Id` string
- `Zuora-Entity-Ids` string
- `Zuora-Org-Ids` string

## Response `200`

List of available metadata objects.

- GetObjectSummary[]
  - `objectName` string, required — Canonical object name from Metastore (DQ/OQ). Casing matches the provider (often lowercase `objectType`); not normalized to PascalCase.
  - `label` string, required — Human-readable label
  - `category` string — Object category (DQ/OQ contexts only)
  - `supportCustomField` boolean, required — Whether this object supports custom fields
  - `href` string — Path to the describe endpoint for this object. The path segment uses the same casing as `objectName`. The server returns this path **without** a `/v1` prefix; combine with the API base URL (e.g. `https://rest.zuora.com`).

## Other responses

- `500` — Internal server error.
- `4XX` — Authentication failed or credentials are invalid.
