How to implement registration through social networks in a mobile application?

Question

Mobile development

Good day!
I am writing an API (in PHP) for a mobile application of one site. The site (written in MODX Revo) implements registration through social networks using Ulogin. Both I and mobile developers have little experience, so the question arose, how to implement this function in a mobile application?

Answer 1

For example, like this:
IOS: https://github.com/ulogin/iOS
Android: https://github.com/ulogin/Android
Or do you need to understand what exactly you want to do so that authorization on the server occurs? No way, the user must agree to oauth authorization and give permission.
