The Nike SNKRS app sometimes releases early access to shoes somewhere hidden in their app. There are a lot of so called "cookgroups" that provide services that constantly check their code I suppose and notify you as soon as something gets added / changed and sends you a discord notification with the location of the added item / thing. Since these groups can cost up to 40€ a month because they offer plenty of different services as well I was wondering how difficult it would be to code such a monitoring program myself and which language I should use and just general tips you can give me.
Thank you in advance. Not sure if this belongs here or in requests, feel free to move the thread.
Best Regards,
