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 from any third-party persistence solution and means that all your data stays in one place. Custom Objects are grouped into containers, which can be used like namespaces.

You can store custom data for Products and other entities in Custom Objects and access the data using Reference Expansion. With this approach, you can query for the custom data associated to the resource without the need for Custom Objects scopes.
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.

value​
Any​
Can be any JSON standard type, such as number, string, boolean, array, object, or a common API data type.
  • 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.

IDs and references that created the CustomObject.

lastModifiedAt​
DateTime​

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

lastModifiedBy​BETA
LastModifiedBy​

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 within value that have null values are not saved.
