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

const textflow = require("textflow.js");
textflow.useKey("YOUR_API_KEY"); //You can create one in the API Console at https://textflow.me

textflow.sendSMS("+381611231234", "Dummy message text...");

Provide custom callback

textflow.sendSMS("+381611231234", "Dummy message text...", (result) => {
  if (result.ok) {
    console.log("SUCCESS");
  }
})

Await response

async function async_function() {
  let result = await textflow.sendSMS("+381611231234", "Dummy message text...");
  console.log(result);
}
async_function();

Example of the result of a successfully sent message

{
    "ok": true,
    "status": 200,
    "message": "Message sent successfully",
    "data": {
        "to": "+381611231234",
        "content": "Dummy message text...",
        "country_code": "RS",
        "price": 0.05,
        "timestamp": 1674759108881
    }
}

Example of the result of an unsuccessfully sent message

{
    "ok": false,
    "status": 404,
    "message": "API key not found"
}

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

Both sendVerificationSMS and verifyCode can also be used both by providing a callback or awaiting its promise, just like the sendSMS.

//User has sent his phone number for verification
textflow.sendVerificationSMS("+11234567890", verificationOptions);

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

//The user has submitted the code
let result = await textflow.verifyCode("+11234567890", "USER_ENTERED_CODE"); 
//if `result.valid` is true, then the phone number is verified. 

Verification options

VerificationOptions the optional argument for the sendVerificationSMS function. It contains the parameters of the verification code that should be sent:

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.

{
  "service_name": "Guest",
  "seconds": 600
}
