@trobert2 Sadly I haven't, but that's a cool idea! From what I've seen the REWE API is pretty straightforward, just try having a look at the data flow using Firefox or Chrome Web Inspector.

@trobert2 i'm also looking into this right now, and trying to build something on top of this, if you want to collaborate on this, feel free to reach out. @cbruegg is there any documentation available, i couldn't find any.

@joalbrecht I don't think there's any official documentation, but at least so far it looks like the API is stable.

@cbruegg The problem is this script is just for the pickup dates not delivery. Wrong script name ;)

To do that kind of stuff you need to login first. Have you managed to login to rewe via API (OAuth, Digest etc.)?

@GoldenToast Sadly the only API calls I'm familiar with are the ones used in this script - haven't played around with the rest
