# Upsert Catalog Object Request

## Structure

`UpsertCatalogObjectRequest`

## Fields

| Name | Type | Tags | Description |
|  --- | --- | --- | --- |
| `idempotencyKey` | `string` | Required | A value you specify that uniquely identifies this<br>request among all your requests. A common way to create<br>a valid idempotency key is to use a Universally unique<br>identifier (UUID).<br><br>If you're unsure whether a particular request was successful,<br>you can reattempt it with the same idempotency key without<br>worrying about creating duplicate objects.<br><br>See [Idempotency](https://developer.squareup.com/docs/build-basics/common-api-patterns/idempotency) for more information.<br>**Constraints**: *Minimum Length*: `1` |
| `object` | [`CatalogObject`](../../doc/models/catalog-object.md) | Required | The wrapper object for the catalog entries of a given object type.<br><br>Depending on the `type` attribute value, a `CatalogObject` instance assumes a type-specific data to yield the corresponding type of catalog object.<br><br>For example, if `type=ITEM`, the `CatalogObject` instance must have the ITEM-specific data set on the `item_data` attribute. The resulting `CatalogObject` instance is also a `CatalogItem` instance.<br><br>In general, if `type=<OBJECT_TYPE>`, the `CatalogObject` instance must have the `<OBJECT_TYPE>`-specific data set on the `<object_type>_data` attribute. The resulting `CatalogObject` instance is also a `Catalog<ObjectType>` instance.<br><br>For a more detailed discussion of the Catalog data model, please see the<br>[Design a Catalog](https://developer.squareup.com/docs/catalog-api/design-a-catalog) guide. |
