Connect Our front end app with our backend API

We have a ionic angular app fully developed on front end, and a functionall deploy API on laravel that Works correctly. So we need to connect both, just make the calls to the endpoints of the API and show the information on the JSON received. The parts of the app are: First we have a view to login and singup, that is connected yet, but not working on the pc version, cause of the token we try to store on the DDBB. Second, we have a view that show a list of motorbikes that are stored on the DDBB, this is by having a call to a endpoint we need to send some atributes to filter on the database and then display the info, we send the info via formData. And lastly a view to display a table that contains the notifications sended to the user. The frontend is developed and also the API, so we just need to make the calls. And when this is done we want to get the apk and the executable for IOS so we can proceed to publicate to the stores. For more information contact me.
