Submit multiple phone numbers in a single request for efficient batch processing.
If you scrub more than 10 phone numbers, use HTTP POST instead of HTTP GET. If you do not know your batch size, safest option is always use HTTP POST. The maximum number of records that can be scrubbed per requests is 10,000. If you have larger batches, consider using SFTP.

​
Processing Multiple Results

const results = await response.json();

const clean = results.filter((r) => r.ResultCode === "C");
const doNotCall = results.filter((r) => r.ResultCode === "D");
const wireless = results.filter((r) => r.IsWirelessOrVoIP === "1");

console.log(`Clean numbers: ${clean.length}`);
console.log(`Do Not Call: ${doNotCall.length}`);
console.log(`Wireless: ${wireless.length}`);

​
Using HTTP POST for Large Batches

For more than 10 phone numbers, use HTTP POST with a JSON body: 
using (var client = new HttpClient())
{
    System.Net.ServicePointManager.SecurityProtocol = System.Net.SecurityProtocolType.Tls12;

    client.DefaultRequestHeaders.Add("loginId", "YOUR_API_KEY");

    var requestBody = new
    {
        phoneList = "5039367187,7075276405,...",
        version = "5",
        output = "csv"  // Recommended for large batches
    };

    var json = System.Text.Json.JsonSerializer.Serialize(requestBody);
    var content = new StringContent(json, System.Text.Encoding.UTF8, "application/json");

    var response = await client.PostAsync(
        "https://www.dncscrub.com/app/main/rpc/scrub",
        content
    );
    var responseString = await response.Content.ReadAsStringAsync();
}

Best Practices

While the API can handle large batches, consider breaking very large lists into batches of 1,000-5,000 numbers for optimal performance.
Use output=csv for large batches. CSV parsing is more efficient for high-volume processing.
Operations are atomic. If one phone number is invalid, the entire batch fails. Validate phone numbers before sending.
