Create a new client

To start making requests you need the API Key. You can find it on your profile page on whoisxmlapi.com. Using the API Key you can create Client.

Most users will be fine with NewBasicClient function.

client := emailverifier.NewBasicClient(apiKey)

If you want to set custom http.Client to use proxy then you can use NewClient function.

transport := &http.Transport{Proxy: http.ProxyURL(proxyUrl)}

client := emailverifier.NewClient(apiKey, emailverifier.ClientParams{
    HTTPClient: &http.Client{
        Transport: transport,
        Timeout:   20 * time.Second,
    },
})

Make basic requests

Email Verification API performs a comprehensive validation of email addresses in real-time and conveniently.

// Make request to get parsed Email Verification API response
evapiResp, _, err := client.EvapiService.Get(context.Background(), "[e-mail]")
if err != nil {
    log.Fatal(err)
}

// Check if an email address is valid
if !*evapiResp.FormatCheck {
    log.Printf("\"%s\" is invalid email address", evapiResp.EmailAddress)
}

// Make request to get raw Email Verification API data
resp, err := client.EvapiService.GetRaw(ctx, "whoisxmlapi.com")
if err != nil {
    log.Fatal(err)
}

log.Println(string(resp.Body))
