I want to write a common API for login in two different projects with two different databases. How can I identify which project call the API and corresponding database to be used for the API function?

More detail, please. What are your using for login verification ?

Thank you. Using email and password both the application's login take place. So can I write a common function to login in both applications? If so how should I identify the database in which the username and password to be checked?

The calling application would need to provide those details to the API.

Thank you. Thats a good idea. Is there any other way so that we can avoid the parameter in the api to identify the application? That is what I am looking for actually.

No, because there is no way a method inside the API can get any useful information about the calling application.

Ok Thank you for the information. I am searching and can't get the answer till now.

An API should be configuration neutral, so that it can work with any application. If it contains information that is specific to a certain application then it should not be an API, but be a part of the application. While you only have two different applications today, you could have more in the future. So the more 'general' the API, the easier it is to implement with future applications.

Thank you very much. Now I understood.
