The official documentation of all the APIs offered by Ebay can be found here.

Ebay API – Parsing API Response in Angular

all – hoping you can help me learn how to parse a JSON response.

I have a service that makes an API call like this:

  private REST_API_SERVER = 'myapicall.com'

  constructor(private httpClient: HttpClient) { }

  public sendGetRequest(): Observable<any> {
   return this.httpClient.get(this.REST_API_SERVER);
  }

The above is returned to a component:

 sendGetRequest(): void {
     this.dataService.sendGetRequest()
       .subscribe(data => this.data = data);

}

I can output the response in my component HTML like this:

{{data | json}}

At which point a response with a structure like this is written to the screen:

        "https://www.ebay.com/sch/i.html?_nkw=iPhone&_ddo=1&_ipg=1&_pgn=1"
      ]
    }
  ]
}

In my component HTML, how would I write this item’s title to the screen?

    I don't understand why (please help educate me if you know), but I got it working by changing the sendGetRequest() function to:

      public sendGetRequest(): Observable<any> {
    return this.http.get(this.REST_API_SERVER);
  }

    Rather than:

     public sendGetRequest(): Observable<any> {
   return this.httpClient.get(this.REST_API_SERVER);
  }

    Assuming that

    const data={complete_json_you_have_provided}

//then

console.log(data.findItemsByKeywordsResponse[0].searchResult[0].item[0].title);

    prints required title array [Apple iPhone 12 mini (5G) Factory Unlocked GSM+CDMA 256GB | 128GB | 64GB]
