How can I use an eBay API to enable my app to submit "ask seller a
question" messages? I'd like it to be able to programmatically send off
questions to specific sellers about their listings.
I'd like to direct users of the eBay app to my items for sale. The link
https://www.ebay.com/sch/sekidata/m.html?LH_Auction=1 opens a web
browser. How can I format the link so it opens within the eBay app?
I took me a while to figure this out, but iOS eBay deep links actually
do work as of late 2023. Below is an example of the syntax. When entered
into Safari it opens the eBay app and shows the correct item.
ebay://com.ebay.mobile/ebay/link/?nav=item.v...
