Plugin to automate filling a grocery shopping app basket

Hi there I am using Bubble to create a recipe and shopping app. I would like to automate the filling of a grocery app shopping basket for my customers. My preferred way of doing this would be to have the user sign in to the shopping app and then use a Selenium-type approach to quickly add grocery products but I can’t think how to do that within the user’s browser. Has anyone built a plugin to help with this?

Using selenium/puppeteer is difficult and hard to keep up to date. One change on the clients website and you need to re-code it.

Kroger has an API that I almost used for a similar project. Check it out

Thank you. I am starting developing the app in the UK and unfortunately the UK retailers have not generally provided APIs. But I will look closely at Kroger.
