Multi Shopify Inventory item ID

Multi Shopify Inventory item ID

Hi,

I am trying to schedule  the update of specific Shopify inventory line item using Zoho Flow.  the flow worked just fine, except the  Inventory item ID only accept one ID entry, if I tried the add multi Inventory item IDs its give me this output error:
Shopify says "Error Code : 400 , Error Message : "
 
I tried to separate the two IDs using comma and semicolon and space  but it didn't work but I got the the above error.

I would appreciate any help in how to add multi IDs on the  Inventory item ID field.

Thanks
