I’m trying to create an app similar to Manychat. I find services like Manychat too expensive, so I’m looking to make one similar for my own personal use. I’ve been reading through the Meta developers’ documentation, and it just seems unclear and overwhelming. It isn’t straightforward and there are too many things we’d have to setup prior or after making this app.

Does anybody have any road path or just steps on which I should implement first to make this app? Something like “Step 1: Make facebook login, Step 2: Bla bla”. Just which steps to take that’s all. I hope it can be as detailed as possible. I tried looking for videos for some more understanding but that is non existent.

All the similar questions on this site have been asked years ago and are outdated since Instagram now has an official API for this. And no, I will not be using an unofficial API since this goes against their terms of use.
