How to login with External Users

Hi Adalo Team and All,

I am beginner to adalo and we have our own membership database and login process.
Can we want to skip the adalo “user” collection and using our api to login?
If the login success, will return below JSON.
status: “OK”,
token: “xxxxxxxxxxxxxxxxxx”,
user: {
name: “user name”,
birth: “2000-01-01”,
contact: “123456789”,
email: “”,
“address”: “zzzzzzzzzzzzzzzz”


Try to created external collections or created new login button but not work.

What is the external user login concept and flow?

Did anyone face or solve this issue? Can anyone please help, or share the idea and concept?

Many Thanks
