uncaught in promise error consumer key is required error.consumerKey is required at new Woocommerce API(localhost:8100/build/vendor.js

[mariadebawi]

I keep having this issue when I try my woocommerce api with this code form my Home.ts Ionic4 Angular7
**```
import {Component} from '@angular/core';
import {NavController} from 'ionic-angular';
import * as WC from 'woocommerce-api';

@component({
selector: 'page-home',
templateUrl: 'home.html'
})

export class HomePage {
Woocommerce: any;
products: any[];

constructor(public navCtrl: NavController) {
this.Woocommerce = WC({
url: '',
Consumerkey: '',
ConsumerSecret: ''
});
this.Woocommerce.getAsyn("products").then((data) => {
console.log(JSON.parse(data.body));
this.products = JSON.parse(data.body).products;
}, (err) => {
console.log(err)
})

}
}

I don't understand the problem also when I try my API on Postman, it gives me
**```

{
  "code": "rest_no_route",
  "data": {
    "status": 404
  },
  "message": "No route was found matching the URL and request method"
