Application programming interface: APIs are mechanisms that enable two software components to communicate with each other using a set of definitions and protocols.

• Show all the databases that we are going to use.
• Show all the classes that we are going to use.

Classes:

• Tell them that we are going to expose API’s for all the functions that the UI needs.

APIs:

• createUser(): HTTP POST

The user will send all the information required for sign-up by using the API exposed by the function. The function will store all the data in the ‘Users’ database.

• login(): HTTP POST

The client application will send the user login details to the backend server to verify user credentials and provide the output to the front-end application. The output will be the profile name and profile picture.

• eventDetails(): HTTP GET
