# Create and update combinations with /product calls

#### What's new

Requests for updating products or creating new ones now support passing combinations in the request body. For example, you can now delete combinations through the [Update product](/api-reference/rest-api/products/update-product.md) call, or add both *options* and *variations for specific option choices* with the [Create product](/api-reference/rest-api/products/create-product.md) call.

This change *does not affect existing apps and workflows*, as changing/creating combinations through `/products` endpoint requires a new query parameter.

#### Changes in API

* <mark style="color:purple;">`PUT`</mark> `/products/{productId}` – API call for updating a product now supports `"combinations": []` array of objects. Any changes to the passed combinations are applied (creating/updating/deleting).
* <mark style="color:blue;">`POST`</mark> `/products` – API call for adding a new product to the store now accepts `"combinations": []` array of objects. You still need to provide the `"options": []` array with the `"choices" :[]` array inside, so added combinations are based on specific choices.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.ecwid.com/changelog/june-2025/june-13/create-and-update-combinations-with-product-calls.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
