Multiple Ionic url

Goodnight,

I am working on the development of an application in ionic, my problem refers to the following at the time of the client to enter will have to specify which company will use to visualize the data of that company, what I need to know is how to configure within a file .ts the different connections to the various companies, Example was trying with the following code
export const MOVILAPP = {
production: ‘Yes’,
apiUrl: ‘http://5.5.5.5/MovilAppWS/api/
};
but I didn’t find a way to add the various urls,
When I am a YYYY company I must use a url and when I am a XXXX company I must use another url Note: I can have more than 6 url to connect

i hope you help me

my english is a litle bad
