Hi,
I want to be able to send Whatsapp messages using Twilio, but I need it to be asynchronously. Here is my code:
public async void EnvioWhatsapp(string TelefonoCelular)
{
const string accountSid = "mySid";
const string authToken = "myToken";
TwilioClient.Init(accountSid, authToken);
var message = MessageResource.Create
(
body: "Hola mundo!",
from: new Twilio.Types.PhoneNumber("whatsapp:+myNumber"),
to: new Twilio.Types.PhoneNumber("whatsapp:+clientNumber")
);
}
In my code EnvioWhatsapp is underlined in green with the message:
"This async method lacks await operators and will run synchronously. Consider using the await operator to await non-blocking API calls..."
I have tried inserting await in multiple areas of the method but nothing works so far, and yes I have been looking at the Twilio api docs, but I cannot find a way to make the call asynchronously.
Thank you, and sorry for the Spanish nomenclature, I know it makes it a little harder to read the code.
According to the docs you should use CreateAsync.
You can either return it as Task, or await it. In any case try to avoid the async void signature. See: https://docs.microsoft.com/en-us/archive/msdn-magazine/2013/march/async-await-best-practices-in-asynchronous-programming#avoid-async-void
