Textflow C# client

Installation

dotnet add package TextFlow

Sending an SMS

To send an SMS, you have to create an API key using the Textflow dashboard. When you register an account, you automatically get an API key with one free SMS which you can send anywhere.

Just send a message

using TextFlow;

TextFlowClient client = new TextFlowClient("YOUR_API_KEY");
client.SendSMS("+381611231234", "Dummy message text...");

Handle send message request result

var res = await client.SendSMS("+381611231234", "Dummy message text...");
if (res.Ok)
    Console.WriteLine(res.Data.Timestamp);
else
    Console.WriteLine(res.Message);

Example properties of the successfully sent message result

result is an instance of TextFlowSendMessageResult class.

{
    "Ok": true,
    "Status": 200,
    "Message": "Message sent successfully",
    "Data": {
        "To": "+381611231234",

        "Price": 0.05,
        "Timestamp": 1674759108881

Verifying a phone number

You can also use our service to easily verify a phone number, without storing data about the phones that you are about to verify, because we can do it for you.

Example usage

//User has sent his phone number for verification
var resultSMS = await client.SendVerificationSMS ("+11234567890", SERVICE_NAME, SECONDS);

//Show him the code submission form
//We will handle the verification code ourselves

//The user has submitted the code
var resultCode = await client.VerifyCode("+11234567890", "USER_ENTERED_CODE");
//if `resultCode.Valid` is true, then the phone number is verified. 

Verification options

SERVICE_NAME is what the user will see in the verification message, e. g. "Your verification code for Guest is: CODE"

SECONDS is how many seconds the code is valid. Default is 10 minutes. Maximum is one day.
