Asynchronous API Call Response

Madan Shekar

Hello everyone,

we are calling asynchronous API's while submiting the form arround 8 API's calling.

Form data will be inserted to database & API's will do the respective operations in diferent application.

As of now we are not waiting for the API response , after successfull inster we are showing success message.

Now i wanted to grab all the API's response , based on the response i will be updating the satatus later so what iam looking is is there any way to capture all the api response in single point without waiting period for application ?

Thanks

Hi Madan Shekhae,
we need to use Task.WhenAll();
Task.WhenAll(AsyncMethod1, AsyncMethod2, AsyncMethod3);
Please refer this example,
private async Task CreateMultipleTasksAsync()
{
  CrimcaseServiceClient client = new CrimcaseServiceClient(
    new BasicHttpBinding(),
    new EndpointAddress("http://192.168.1.100/EndPonutUrl")
    );

  // Start the three asynchronous calls.
  var getFirstTask = client.GetFirstAsync(eventInfo);
  var getSecondTask = client.GetSecondAsync();
  var getThirdTask = client.GetThirdAsync();

  // Asynchronously wait (await) for them all to complete.
  await Task.WhenAll(getFirstTask getSecondTask, getThirdTask)

  // Retrieve the results of the calls.
  var event = await getFirstTask
  var locations = await getSecondTask
  var types = await getThirdTask

  // TODO: Your remainin logic after getting response from all task

Hi Madan,

If you are using Javascript then try Promise.

Sample:
await Promise.all([someCall(), anotherCall()]);
Results sample:
let [someResult, anotherResult] = await Promise.all([someCall(), anotherCall()]);
