Custom Objects

Custom Objects store arbitrary JSON-formatted data on commercetools Composable Commerce.

Custom Objects allow you to persist data that does not fit the standard data model. This frees your application completely from any third-party persistence solution and means that all your data stays in one place. They are grouped into containers, which can be used like namespaces.

You can use Custom Objects to store custom data for a Product as an AttributeReferenceType Attribute. For other entities, you can store custom data as a ReferenceType Custom Field by setting referenceTypeId to key-value-document. When you do this, any data stored in the Custom Object is accessible using Reference Expansion, and no additional scopes are required.

A maximum number of 20 000 000 Custom Objects can be created per Project. Learn more about this limit.

Representations

CustomObject

id​
String​

Unique identifier of the CustomObject.

version​
Int​

Current version of the CustomObject.

key​
String​

User-defined unique identifier of the CustomObject within the defined container.

MinLength: 1​MaxLength: 256​Pattern: ^[-_~.a-zA-Z0-9]+$​

JSON standard types Number, String, Boolean, Array, Object, and common API data types. For values of type Reference the integrity of the data is not guaranteed. If the referenced object is deleted, the API does not delete the corresponding reference to it and the value points to a non-existing object in such case.

createdAt​
DateTime​

Date and time (UTC) the CustomObject was initially created.

createdBy​BETA
CreatedBy​

IDs and references that created the CustomObject.

lastModifiedAt​
DateTime​

Date and time (UTC) the CustomObject was last updated.

lastModifiedBy​BETA
LastModifiedBy​

IDs and references that last modified the CustomObject.

CustomObjectPagedQueryResponse

PagedQueryResult with results containing an array of CustomObject.

limit​
Int​

Number of results requested.

offset​
Int​

Number of elements skipped.

count​
Int​

Actual number of results returned.

total​
Int​

The total number of results matching the query. This number is an estimation that is not strongly consistent. This field is returned by default.

String​

Unique identifier of the referenced CustomObject.

typeId​
String​

Create or Update CustomObject

POST
https://api.{region}.commercetools.com/{projectKey}/custom-objects

If an object with the given container/key exists, the object will be replaced with the new value and the version is incremented. If the request contains a version and an object with the given container/key, then the version must match the version of the existing object. Concurrent updates to the same Custom Object returns a ConcurrentModification error even if the version is not provided.

Fields with null values will not be saved.
