Continuation from above.

Now when i add input in Code By Zapier, than i have to select SKU and quantity for each product. It is not coming as string for eg→ skuofproduct1, skufproduct2

I think because of i have to select each SKU, i am not able to run code by zapier action which is mentioned above.

Hey there! This will depend on the output that comes from the webhook - whether it’s fixed or variable dependent on the number of items you’re working with.

If it’s fixed like Items: Item 1, Item 2, Item 3 - You can definitely loop over it in a code step

If it’s variable like : 

Item1: Item 1

Item 2: Item 2

Item 3: Item 3 etc…

Then you’ll not have a way to determine which line items to send to a code step, and yes you’re right, it won’t be possible. The way to do this instead would be to make the API call using requests in the code step - That way you can determine the length of the array and use something like map with the returned value. Some more information on this can be found here:
