CrossClassify React SDK

The CrossClassify SDK for react apps, which helps to collect metadata of users activity like page navigation and form interactions.

Prerequisites

• node 16 (or later)

SDK Integration Guide

First, install xc-sdk-react as a dependency:

npm install --save xc-sdk-react

follow the steps below to integrate with your app or skip to a complete example

Step 1: Loading and initializing XC package

1. Setup the page view tracker using initializer in one of these two ways:

   • Option A: Call initXC(your_site_id, your_api_key) in the index.js or app.js once. (Recommended)
   • Option B: Call initXC(your_site_id, your_api_key) in the ComponentDidMount in any component that you want to track its form.

2. Pass your site_id and api_key to initXC(your_site_id, your_api_key) function.

• Get site_id and api_key from app.crossclassify.com by creating a new web app in a project.

import { initXC } from "xc-sdk-react";

// Class Components
componentDidMount(){
   initXC(your_site_id_from_app.crossclassify.com, your_api_key_from_app.crossclassify.com);
};

import { initXC } from "xc-sdk-react";

// Functional Components
useEffect(() => {
  initXC(your_site_id_from_app.crossclassify.com, your_api_key_from_app.crossclassify.com);
}, []);

Step 2: Track the form

For each page that contains a form (e.g. signup, login) do the following instructions.

Step 2.1: Specify the form

1. Add property "name" to your form tag.

   • Account Opening Service:
     • Form name must contains "signup" substring, examples: "signup-form", "my-signup", etc.
   • Account Takeover Service:
     • Form name must contains "login" substring, examples: "login-form", "my-login", etc.

2. Add custom-attribute="include-form-tracking" to the form which you want to track.

   <form
     name="must-contain-signup-or-login-substring"
     custom-attribute="include-form-tracking"
   >
   </form>

Step 2.2: Specify the form fields

• Add custom-attribute="include-content-tracking" to the input which you want to track its content.

  Important: Signup (or login) form must include an input with the name="email".

  Important: Must set custom-attribute="include-content-tracking" for email input.

  Note: Sending field contents increases the accuracy of the CrossClassify fraud detection algorithm. Hence, content tracking is HIGHLY RECOMMENDED on all non-confidential fields.

  <input
    name="email"
    custom-attribute="include-content-tracking"
    type="text"
    onChange={handleChange}
  />

Step 2.3: Specify submit button

• Add custom-attribute="form-submit" or type="submit" to the submit button.

  Important: Use onSubmit={submitHandler} for you button NOT onClick={clickHandler}.

  <button custom-attribute="form-submit">submit</button>

Complete Example

Example 1:

// Sample usage of the package
import { useState, useEffect } from "react";
import { initXC } from "xc-sdk-react";

const initialState = {
  name: "",
  family_name: "",
  username: "",
  email: "",
};

const Form = () => {
  const [state, setState] = useState(initialState);

   useEffect(() => {
    // get your_site_id and your_api_key from app.crossclassify.com, after creating an app in a project
    initXC(your_site_id, your_api_key);
   }, []);

  const handleChange = (event) => {
    let name = event.target.name;
    let value = event.target.value;
    setState((prevState) => ({
      ...prevState,
      [name]: value,
    }));
  };

  const handleSubmit = (event) => {
    event.preventDefault();
  };

  return (
    <div>
      // 1- Your <form> name attribute must contain "signup" or "login" substring, examples: "signup-form", "my-login", ... .
      // 2- Add custom-attribute="include-form-tracking" to the form tag which you want to track.
      <form
        name="must-contain-signup"
        onSubmit={handleSubmit}
        custom-attribute="include-form-tracking"
      >
        // 1- Signup form must include an input with the name="email".
        // 2- Must add custom-attribute="include-content-tracking" for the email input
        // note: Sending field contents increases the accuracy of the CrossClassify fraud detection algorithm. Hence, content tracking is HIGHLY RECOMMENDED on all non-confidential fields.

        <label>Name: </label>
        <input
          custom-attribute="include-content-tracking"
          type="text"
          name="name"
          onChange={handleChange}
        />

        <label>Family Name: </label>
        <input
          custom-attribute="include-content-tracking"
          type="text"
          name="family_name"
          onChange={handleChange}
        />

        <label>Username: </label>
        <input
          custom-attribute="include-content-tracking"
          type="text"
          name="username"
          onChange={handleChange}
        />

        <label>email: </label>

        <input
          custom-attribute="include-content-tracking"
          type="email"
          name="email"
          onChange={handleChange}
        />

        // Add custom-attribute="form-submit" or type="submit" to the submit button.
        // Use onSubmit={submitHandler} for you button NOT onClick={clickHandler}.
        <button custom-attribute="form-submit">submit</button>
      </form>
    </div>
  );
};

export default Form;

Example 2: Material UI (MUI) "Form"

• If you are not using pure HTML tags (form, input and button), consider adding the mentioned attributes to the rendered HTML tags. like using "inputProps". Pay attention to the following example of Matrial UI (MUI) "TextField".

   //simple MUI "Form" tracking integration
  <Box

    // Name attribute must contain "signup" or "login" substring
    name="signup-form" 
    component="form"
  >
     <TextField
      // Adding properties to the HTML <input> tag using inputProps
      inputProps={{
        "custom-attribute": "include-content-tracking",
        name: "email",
      }}
      type="text"
      value={email}
      onChange={handleChange}
      label="email"
    />
    <Button
      id="signup-btn"
      // must use onSubmit
      onSubmit={onSignup}
      variant="contained"
      size="large"
      type="submit"
    >
    Signup
    </Button>
  </Box>

Now go to dashboard and check if your signup submits are shown up in the "Registrations" menu. Congratulations! You're done!

Steps of Troubleshoot:

Attribute:

• Make sure all mentioned attributes in the form integration section assigned to the raw HTML tags using browser's inspect dev tools.
  • Some times libraries like MUI does assign attributes to the parent div tag! (which mentioned to use inputProps)

Network:

• Make sure that data transfers to CrossClassify with status 200 OK, on both page navigation and form submission.
  • Sometimes api-key missed to pass to initXC function and raised for 403!
  • Make sure the form submit signal triggered when clicking on the submit button.
  • Sometimes, form submit event are not fired by clicking on the form submit button.As mentioned before, use onSubmit attribute.
