Business Messenger SMS - SDK


To proceed with the integration of SMS Form SDK to your HTTPS web site you must meet the following conditions:

  • Locate your Form configuration from HORISEN Business Messenger Application
  • Download or use SMS Form SDK

1. Introduction

SMS Form SDK is a javascript library that provides a subscription mechanism for SMS messages for your website.

After a visitor subscribes you will be able to send him SMS messages using standard Business Messenger campaigns.

The SDK can be used directly from javascript so that you can build your own custom subscription forms and collect some other information to be populated per contact in Business Messenger Contact Manager.

2. Setup


It is implied that the user has Business Messenger account and access.

Business Messenger Form

In the Business Messenger App go to Form section, create a Web Form, and find your configuration under form view from the grid, which you will use later in configuring the SDK.

3. Integration

Initialize SDK

Include SDK script in your page:

<script type="text/javascript" src=""></script>

Initialize SDK

    window.hproSMSFormAsyncInit = function() {
        window.SMSForm = hproSMSForm.initForm({
            url: "",

Set configuration and SDK just before the end of </body> tag

Google reCaptcha

reCAPTCHA protects against spam and other types of automated abuse.
Google reCaptcha is to be implemented by the developer who is implementing this SDK.
reCaptcha sitekey that is needed for initializing reCaptcha can be found in Business Messenger app, Opt-in/Opt-out Forms section, under form view from the grid.
More info about implementing Google reCaptcha can be found here.

4. Configuration SDK Properties

Property Type Params Description
initForm function Object
Key Type Description Required
url string Defines Form and API URL. Yes
Parameters are obtained in the Business Messenger app after creating SMS Web Form, under form view from the grid.

After SDK is initialized we can now use it to subscribe or unsubscribe users.
Subscribing or unsubscribing is a two-step process. After submitting the form, "code" is sent to users' mobile number via SMS. That code must be sent in the second step.

First step example:

let data = {
    identifier: '+12025550183',
    option_uuids: 'fac1f6dd-e11b-4ab6-9812-a03302812233,1d722df4-1b3a-1ff1-81d2-d76075b12677',
    recaptcha: "03AGdBq24kHszPYZ85tzyVMU-C2uN998wWzWJDZnHCyyZQoKScVgFWvT28b21Q67DaNgYFg5kCvl1T...", // recaptcha code is much longer than in this example
    type: 'in'
    // on request success
    // here we can now enable part of the form where user can input code that he recived on his mobile phone
    // we need to reset recaptcha here
    // on request error
    // here we can notify user that there was an error and to try again
    // we also need to reset recaptcha here

After the first step is successful, we need to send code that the user received on his mobile phone via SMS message.

Second step example:

let data = {
    code: '6465865',
    //here we can send additional data about user
    first_name: 'John',
    last_name: 'Smith'
    //on request success
    // here we can reset all form data and allow for another subscription
    // on request error
    // if error is invalid code than we can inform user and ask him to enter it again or notify about error and reset form
Property Type Params
submitForm function Object
Key Type Values Description Required
identifier string Mobile phone number of a user that is subscribing/unsubscribing in international format Yes
option_uuids string Coma separated array of option UUIDs witch users selected to subscribe/unsubscribe to/from. No
recaptcha string ReCaptcha code. ReCaptcha is implemented by the form using SDK Yes
type string in
Defines if the form is used to subscribe (in) or unsubscribe (out) the user Yes
submitCode function Object

If the form is used to unsubscribe the user ("type": "out"), then additional user data will not be saved so there is no need to send them.
If additional user data is sent it will be ignored by API.

5. Example

Here is a working example of SDK in action. In order for this example to work all parameters should be replaced with real ones and run in a localhost environment (e.g. http://localhost:3000/).

Note that the port number can be changed.
