mobile app login with REST API
Application Type

Hi All,

We have a Web Application that is not developed on outsystems. now we are developing mobile app for this web app in outsystems.
for mobile app everything is going to be a External REST API calls. (all data including Login).

I want to login the mobile app with REST API without using Users module and default Login actions.

Is it possible to develop a app without using outsystems Users Module.?

Dear Navaneethan,
Greetings of the day

Yes, you can use external login instead of using default login of OutSystems.

You can remove call to default login method from login button from screen and then call your required rest API.
After getting response, you can create functionality accordingly.

Just to mention, you will not be able to use user related functionality after using your own login mechanisms.

Check following URLs from OutSystems related to External Login.

Most importantly, if you don't use Users, you can not use roles.
