Send mail using SendGrid in mvc

Question

I'm sending confirmation mail using SendGrid to confirm email but ApiKey always null

public Task SendAsync(IdentityMessage message)
{

    var ApiKey = Environment.GetEnvironmentVariable("ApiKeyFromSendGrid");
    var client = new SendGridClient(ApiKey);
    var from = new EmailAddress("XXX@gmail.com", "Any Name");
    var subject = "Sending with SendGrid is Fun";
    var to = new EmailAddress(message.Destination, "Any Name");
    var plainTextContent = "and easy to do anywhere, even with C#";
    var htmlContent = "<strong>and easy to do anywhere, even with C#</strong>";
    var msg = MailHelper.CreateSingleEmail(from, to, subject, plainTextContent, htmlContent);
    var response = client.SendEmailAsync(msg);

    return response;

}

where is the error? enter image description here

It means an environment variable with such key doesn't exist. Check that the key is correct. Debug. — bolkay, May 12 '19 at 20:25
Seems strange to use an environment variable for this. Why not store the value in your .config file? — ADyson, May 13 '19 at 17:04

The error is in the recovery of the environment variable:

Environment.GetEnvironmentVariable("ApiKeyFromSendGrid");

The ApiKeyFromSendGrid exist?

See if these questions and answers help you to retrieve the environment variable correctly:

@OmarSeleim Ok, but the image shows the key being displayed on the site. Did you set it as the environment variable? In your system does it exist? – George Wurthmann May 12 '19 at 21:47
API KEYS begin with "SG." Please see my answer above. – Justin Steele May 13 '19 at 17:34
I will use as var ApiKey = Environment.GetEnvironmentVariable("SG.Tob9Zs...-...."); or like var ApiKey = ("SG.Tob9Zs...-...."); ?? – Omar Seleim May 14 '19 at 11:56

You're using the wrong value for the API Key. You are using the API Key ID. You'll probably need to create a new key if you didn't store the original key value somewhere.

See SendGrid API Key not working. "The provided authorization grant is invalid, expired or revoked"
