First in an Ionic/Angular project you'll need to import HttpClient in your TS file or service. And then use it in your function.

 import { HttpClient } from '@angular/common/http';
 constructor(private http: HttpClient) {}

You need to understand that you'll get a result as an Observable (https://angular.io/guide/observables). For your function to work, you'll need to subscribe to it.

Example you have a function in a service.ts file:

getData(id: string) {

 return this.http.get(url, option or what the api need)
 // you might need to use observable manipulation like pipe or map to get the data you want


}

In the ts file you use the service :

 import {service} from 'Service'

 constructor (private service: Service) {}


 function() {
    service.getData(id).subscribe(res => {
     console.log(res)

    })
 }
