Hi @Reneta Gesheva ! Thanks for reaching out! In general, more info can be found on our Shopify - Iterable integration docs in terms of what is possible with this integration: https://support.iterable.com/hc/en-us/articles/360021730551-Integrating-Shopify-with-Iterable- .

To make sure I'm understanding your question specifically, are you asking about sending custom data fields in the events you're passing from Shopify to Iterable? Are there any specific API endpoints you're referring to?
