You can use the HttpClient class provided by the .NET Core framework or you can use RestSharp. Using HttpClient: using (var client = new HttpClient()) { var request = new HttpRequestMessage(HttpMethod.Get, apiUrl); request.Headers.Add("Authorization", "Bearer your-access-token"); var response = await client.SendAsync(request); if (response.IsSuccessStatusCode) { var responseBody = await response.Content.ReadAsStringAsync(); } else { throw new Exception($"Failed to call remote API. Status code: {response.StatusCode}"); } } Using RestSharp: using RestSharp; public void CallRemoteApi(string apiUrl) { var client = new RestClient(apiUrl); var request = new RestRequest(Method.GET); IRestResponse response = client.Execute(request); if (response.IsSuccessful) { var responseBody = response.Content; } else { throw new Exception($"Failed to call remote API. Status code: {response.StatusCode}"); } }

Hello Meghana M, To call another server's API from your own API built with Entity Framework Core to read and write data for a particular class, you can use the HttpClient class provided by .NET Core. Here's an example of how you can use HttpClient to call an API: using System.Net.Http; using System.Net.Http.Headers; // create a new instance of HttpClient var httpClient = new HttpClient(); // set the base address of the API you want to call httpClient.BaseAddress = new Uri("https://example.com/api/"); // set the content type of your request httpClient.DefaultRequestHeaders.Accept.Clear(); httpClient.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json")); // make a GET request to retrieve data from the API var response = await httpClient.GetAsync("some-class"); // check if the response was successful if (response.IsSuccessStatusCode) { // read the response content as a string var responseString = await response.Content.ReadAsStringAsync(); // deserialize the response content into your class var responseData = JsonConvert.DeserializeObject (responseString); // use the data retrieved from the API as needed } else { // handle the error } To write data to the API, you can use the HttpClient's PostAsync or PutAsync methods to send data to the API. using System.Net.Http; using System.Net.Http.Headers; // create a new instance of HttpClient var httpClient = new HttpClient(); // set the base address of the API you want to call httpClient.BaseAddress = new Uri("https://example.com/api/"); // set the content type of your request httpClient.DefaultRequestHeaders.Accept.Clear(); httpClient.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json")); // create the data you want to send to the API var data = new YourClass { /* set properties */ }; // serialize the data into a JSON string var json = JsonConvert.SerializeObject(data); // create a new StringContent instance with the serialized JSON data var content = new StringContent(json, Encoding.UTF8, "application/json"); // send a POST request to create new data in the API var response = await httpClient.PostAsync("some-class", content); // send a PUT request to update existing data in the API var response = await httpClient.PutAsync("some-class", content); // check if the response was successful if (response.IsSuccessStatusCode) { // handle the success } else { // handle the error } You should always handle errors and exceptions that may occur when making API calls
