Some of the entities you sync to Yotpo already have their own identifiers in your store’s backend.
Once created in Yotpo, these entities have two different types of ID:

external_id: This is the merchant's unique ID for an order, product, product variant, or collection. Once this ID has been created in Yotpo, it cannot be edited.
yotpo_id: This is the ID that Yotpo assigns to that same order, product, product variant, or collection when it is created in Yotpo.

You'll need your yotpo_id for performing actions on entities you created for Orders, Products, Product Variants, and Collections.

You can easily resolve your external_id to a yotpo_id by using the Retrieve endpoints for each entity. These endpoints take your external_id and respond with your requested data, along with the yotpo_id.

Example flow for creating and updating a product

Create a new product in Yotpo using the [Create product] (ref:create-product) endpoint.
In order to update this product, you'll need its Yotpo product ID. To get this ID, use the [Retrieve products] (ref:retrieve-products) endpoint with your external ID to resolve the Yotpo ID for this entity.
Update the product using the [Update product] (ref:update-product) endpoint. The Yotpo_product_id in the URL is the yotpo_id parameter you received in the [Retrieve products] (ref:retrieve-products) endpoint.
