SignTools VS Watusi-for-WhatsApp

check this out https://github.com/SignTools/SignTools (personally haven't tried it)

There are two components to self-hosting SignTools, the web frontend, and the actual signing server, the latter of which must be run on macOS. Fortunately there's a guide to set it up so that you use GitHub Actions as the signing server, which gives you a certain amount of free minutes per month. I've never gotten close to the limit, even when I'm signing a few dozen apps. The guide also shows you how to set up the web frontend on Railway, which also offers free monthly credits, so you can actually self-host both components for free: https://github.com/SignTools/SignTools/blob/master/INSTALL-SIMPLE.md

SignTools (it's nice for developers with Apple Developer Accounts), for regular users it's kind of a hustle

The SignTools developer (tool that I used to sign other apps with working push notifications) said this about the document posted above:

im new to this i used to use appdb but i kept getting revoked so now i got a dev account for me to make apps and also use it to sideload idk what app to use , i saw some people talk about SignTools to get notification is there any other way to get notification other than that app? i only use it for cercube and rocket insta so please help

Keeping the original bundle ID is required, but not enough for PN working. You have to use a distribution certificate & an explicit profile with the correct PN entitlement. AltStore/Sideloadly cannot do it so you have to do it manually. I recommend you take a look at SignTools if you need working PN: https://github.com/SignTools/SignTools

This is quite easy to do if you are using SignTools. When signing an app, make sure to select Use custom when choosing bundle identifier options and specify it in the aforementioned format. When it's signed, your sign in should work.

watusi?

Probably. Add their source to your package manager and find out if the tweak is updated to iOS16+. If it’s not, follow the instructions on their github for sideloading it via AltStore.

this is the only whatsapp mod that is updated regularly, i dont think it has the feature that you need but you can give it a try

Now, what I wanted to do is being able to do the same thing for Watusi. Tried a lot of stuff but was not able to get push notifications. First, I thought it was related to Watusi dev deleting the push notifications capability (because its page says that sideloaded watusi wont have push notifications) but I researched a lot and it seems to be caused by how WhatsApp bundles their app.

Yes, with AltStore, following the guide from the Watusi developer.
