You will be asked to implement Merge Link. Use the following code snippets to help you: 

(The following is a Django Rest Framework and React implementation of Merge Link.) views.py: ``` from rest_framework.decorators import api_view from rest_framework.response import Response import requests @api_view(['POST']) def create_link_token(request): body = { "end_user_origin_id": request.data.get('organization_id'), "end_user_organization_name": request.data.get('organization_name'), "end_user_email_address": request.data.get('email_address'), "categories": request.data.get('categories', []) } headers = {"Authorization": f"Bearer {request.data.get('api_key')}"} link_token_url = "https://api.merge.dev/api/integrations/create-link-token" link_token_result = requests.post(link_token_url, data=body, headers=headers) link_token = link_token_result.json().get("link_token") return Response({"link_token": link_token}) @api_view(['GET']) def retrieve_account_token(request, public_token): headers = {"Authorization": f"Bearer {request.headers.get('api_key')}"} account_token_url = "https://api.merge.dev/api/integrations/account-token/{}".format(public_token) account_token_result = requests.get(account_token_url, headers=headers) account_token = account_token_result.json().get("account_token") return Response({"account_token": account_token}) ``` urls.py: ``` from django.urls import path from .views import create_link_token, retrieve_account_token urlpatterns = [ path('create-link-token/', create_link_token, name='create-link-token'), path('retrieve-account-token/<str:public_token>/', retrieve_account_token, name='retrieve-account-token'), ] ``` app.js ``` import React, { useState, useCallback } from "react"; import axios from 'axios'; import { useMergeLink } from "@mergeapi/react-merge-link"; const App = () => { const [linkToken, setLinkToken] = useState(null); const onSuccess = useCallback((public_token) => { // Call backend to retrieve account token axios.get(`http://localhost:8000/merge-app/retrieve-account-token/${public_token}/`, { headers: { 'api_key': 'YOUR_API_KEY' }}) .then(res => { console.log('Account Token: ', res.data.account_token); }) .catch(err => { console.error(err); }) }, []); const { open, isReady } = useMergeLink({ linkToken, onSuccess, }); // Generate link token when component mounts React.useEffect(() => { const body = { organization_id: 'ORG_ID', organization_name: 'ORG_NAME', email_address: 'EMAIL_ADDRESS', categories: ['hris', 'ats', 'accounting', 'ticketing', 'crm'], api_key: 'YOUR_API_KEY' }; axios.post('http://localhost:8000/merge-app/create-link-token/', body) .then(res => { setLinkToken(res.data.link_token); }) .catch(err => { console.error(err); }) }, []); return ( <button disabled={!isReady} onClick={open}> Preview linking experience </button> ); }; export default App; ``` The FE can also be implemented in Vue, with: ``` <template> <section> <merge-link :linkToken="ADD_GENERATED_LINK_TOKEN" v-bind="{ onSuccess }" /* :tenantConfig="{ apiBaseURL: 'https://api-eu.merge.dev' OR your specified single tenant API base URL }" */> <template slot="button" slot-scope="props"> <!-- Replace with your preferred view --> <button @click="props.onClick">Open Merge Link</button> </template> </merge-link> </section> </template> <script> import MergeLink from "@mergeapi/vue-merge-link"; export default { components: { MergeLink }, methods: { onSuccess(token) { // Pass token to your backend (Step 3) }, }, }; </script> ``` The FE can be done in vanilla JS/HTML with: ``` <button id="open-link-button">Start linking</button> <script src="https://cdn.merge.dev/initialize.js"></script> <script type="text/javascript"> const button = document.getElementById("open-link-button"); button.disabled = true; function onSuccess(public_token) { // Send public_token to server (Step 3) } MergeLink.initialize({ // Replace ADD_GENERATED_LINK_TOKEN with the token retrieved from your backend (Step 1) linkToken: "ADD_GENERATED_LINK_TOKEN", onSuccess: (public_token) => onSuccess(public_token), onReady: () => (button.disabled = false), // A value of `true` for `shouldSendTokenOnSuccessfulLink` makes Link call `onSuccess` // immediately after an account has been successfully linked instead of after the user // closes the Link modal. shouldSendTokenOnSuccessfulLink: true, // tenantConfig: { // apiBaseURL: "https://api-eu.merge.dev" /* OR your specified single tenant API base URL */ // }, }); button.addEventListener("click", function () { MergeLink.openLink(); })</script> ```
