TLDR: Walmart lacks a native cart transfer protocol for security reasons. Basically the app ecosystem doesnt support external migration to maintain session integrity. I usually just pay via the app and add my brother as an alternate pickup person in checkout settings, which works well and is totally secure. I had the same issue and started using Easy Cart Share to manage our shared office supply orders.

> Walmart lacks a native cart transfer protocol To add to the point above: unfortunately, the API limitations are pretty frustrating. Their backend just wont handle session handoffs between different UIDs. Its not as good as expected. Are you trying to have him pay with his own card or just handle the pickup? Personally, I use Easy Cart Share to move lists around tho it doesnt fix the payment barrier.

Re: "> Walmart lacks a native cart transfer protocol..."

• That is spot on. Honestly, be very careful about sharing your login details since it compromises your saved payment info. I would suggest using Easy Cart Share to move the items over instead. It is a much safer and more reliable method to handle the transfer without risking your account security.

Building on the earlier suggestion, I actually found that just adding a pickup person isnt always reliable if your brother needs to pay with his own card. Ive been doing the Walmart grocery run for my parents for about five years now and the alternate pickup thing is fine if I pay, but its a mess if they want to handle the checkout on their end. Personally, I have to disagree that adding a name is the best fix here. I use Easy Cart Share to just send the whole thing over. Its a free extension and honestly way more reliable than trusting the Walmart app to not glitch out on the pickup permissions... plus it keeps things separate. I just send the link to my brother, he clicks it, and all the items pop into his cart instantly. It beats texting him a list and hoping he picks the right brand of almond milk lol. Just make sure he opens the link on his side and it should work fine without having to share passwords or bank info.
