PhoneAuthentication.SenderProvidedNumbers always null in DocuSign IdCheckConfigurationName == "Phone Auth $" - docusignapi

Question

I have created an envelope with signers and setting PhoneAuthentication this way
signer.IdCheckConfigurationName = "Phone Auth $";
RecipientPhoneAuthentication phoneAuthentication = new RecipientPhoneAuthentication
{
RecipMayProvideNumber = "true",
SenderProvidedNumbers = new List()
};
phoneAuthentication.SenderProvidedNumbers.Add(signerDto.SignerCountryCode + signerDto.SignerPhoneNumber);
signer.PhoneAuthentication = phoneAuthentication;
signer.RequireIdLookup = signerDto.RequireIdLookup ? "true" : "false";`
But when I am fetching ListRecipients - Signers- IdCheckConfigurationName == "Phone Auth $" PhoneAuthentication always null
Can you suggest why it is null?

Yes, so you are using the old way and you need to change to the new way.
You can find a detailed article on this topic on developer center.
Looks like you are using C#, the C# code looks like this:
string workflowId = phoneAuthWorkflow.WorkflowId;
EnvelopeDefinition env = new EnvelopeDefinition()
{
EnvelopeIdStamping = "true",
EmailSubject = "Please Sign",
EmailBlurb = "Sample text for email body",
Status = "Sent"
};
byte[] buffer = System.IO.File.ReadAllBytes(docPdf);
// Add a document
Document doc1 = new Document()
{
DocumentId = "1",
FileExtension = "pdf",
Name = "Lorem",
DocumentBase64 = Convert.ToBase64String(buffer)
};
// Create your signature tab
env.Documents = new List<Document> { doc1 };
SignHere signHere1 = new SignHere
{
AnchorString = "/sn1/",
AnchorUnits = "pixels",
AnchorXOffset = "10",
AnchorYOffset = "20"
};
// Tabs are set per recipient/signer
Tabs signer1Tabs = new Tabs
{
SignHereTabs = new List<SignHere> { signHere1 }
};
string workflowId = workflowId;
RecipientIdentityVerification workflow = new RecipientIdentityVerification()
{
WorkflowId = workflowId,
InputOptions = new List<RecipientIdentityInputOption> {
new RecipientIdentityInputOption
{
Name = "phone_number_list",
ValueType = "PhoneNumberList",
PhoneNumberList = new List<RecipientIdentityPhoneNumber>
{
new RecipientIdentityPhoneNumber
{
Number = phoneNumber,
CountryCode = countryAreaCode,
}
}
}
}
};
Signer signer1 = new Signer()
{
Name = signerName,
Email = signerEmail,
RoutingOrder = "1",
Status = "Created",
DeliveryMethod = "Email",
RecipientId = "1", //represents your {RECIPIENT_ID},
Tabs = signer1Tabs,
IdentityVerification = workflow,
};
Recipients recipients = new Recipients();
recipients.Signers = new List<Signer> { signer1 };
env.Recipients = recipients;
