Want to integrate my angular application with another existing website

[Kiran Rathod]

I have a requirement to develop a third party angular application and integrate it with existing website.

They will call my angular application from their main website with some headers(like userId etc). So I have to fetch those headers and validate headers with database and after successful validating, I have to redirect to dashboard page of angular..

I am using spring boot java as backend by creating REST apis and for frontend I am using angular.

I am confused how to develop this functionality.

Please help.

I would look at Angular Elements as a mechanism to deploy your app. That is probably the easiest way to do this. 

Otherwise, you are going to need to look into microfrontends with Angular, which is a lot more involved, but just as effective (possibly more effective).
