Add Rows API - Not showing any data

Bilawal Nisar

I have a sheet where i have 2 columns. I have Customer and Item.

1. In Customer Column I have a list of customers already
2. * Customer * * ITEM *

row 1 Office
row 2 Shop row 3 Logistics row 4 Constructions row 5 Mapping row 6 Cartoon row 7 Office 2
row 8 Shop row 9 Logistics row 10 Constructions row 11 Mapping row 12 Cartoon

However, when ever I am running my code it says Rows added successfully for all customers with the specified items. But for some reason in smartsheet my data doesn't show up?
