eBay Confirming Publish Offer on Sandbox Ebay

Question

I'm able to successfully post to the Publish Offer API endpoint. It returns a 200 status.

However when I go to the sandbox.ebay.com and search for the product I can't find it. It says 1 product found but it does not appear as a listed item.

https://www.sandbox.ebay.com/sch/i.html?&_from=R40&_trksid=p2334524.m570.l1313.TR0.TRC0.H0.XPRC%20Apple%20Watch.TRS0&_nkw=PRC%20Apple%20Watch&=&LH_TitleDesc=0&_odkw=PRC%20App%20Watch

Is there another API I need to call? I am using this eBay reference tool: https://developer.ebay.com/my/api_test_tool?index=0&api=inventory&call=offer__POST&variation=json
