The free plan is limited to Shopify development stores with no more than 25 existing products. Each import can include up to 5 product IDs and 5 category IDs.

The following information is stored:

1. A mapping of commercetools product ID to Shopify product ID. This is used to efficiently import products into Collections

2. Your Shopify store email address

3. Import results and logs

4. Data entered while using the app. E.g. commercetools API client details (the secret is encrypted in the database), mappings, general settings

Existing products and collections are updated if they have previously been imported using this app. Matching is done via a commercetools-id metafield stored on each Shopify resource.

If products have been imported outside of this app then the import will fail for those products.

Add the commercetools attribute names to "Variant Attributes for Options" in your product mapping. The importer builds Shopify options and variant option values from those attributes. Shopify supports a maximum of 3 options per product.
