Omin Channel Customer API Limitation
The limitations on the eCom API (write) permissions is very much an issue. At least for the product details, height/length/width/weight/description there is a viable workaround using the .csv file import tool. Today, I realized that I am not able to write to related products either. Technically I am not sure why I don't have the ability to write to that field as it calls for ecom product id's, nothing related to Retail at all. Also, there isn't any plausible workaround for me to use such as a csv file import. The only option is for me to manually update 15,000 + products with related products.......not a plausible solution.
