        ```
        
        ---
        ## Authentication
        All API requests go through Xero's OAuth 2.0 gateway and require a valid `access_token` to be set on the `client` which appends the `access_token` [JWT](https://jwt.io/) to the header of each request.
        
        If you are making an API call for the first time:
        
        1. Send the user to the Xero authorization URL
        ```python
        @app.route("/login")
        def login():
            redirect_url = url_for("oauth_callback", _external=True)
            session["state"] = app.config["STATE"]
            try:
                response = xero.authorize(callback_uri=redirect_url, state=session["state"])
            except Exception as e:
                print(e)
                raise
            return response
        ```
        2. The user will authorize your application and be sent to your `redirect_uri`. This is when and where to check that the returned "state" param matches that which was previously defined. If the "state" params match, calling the oauth library's `authorized_response()` method will swap the temporary auth code for an access token which you can store and use for subsequent API calls.
        ```python
        @app.route("/callback")
        def oauth_callback():
            if request.args.get("state") != session["state"]:
                return "Error, state doesn't match, no token for you."
            try:
                response = xero.authorized_response()
            except Exception as e:
                print(e)
                raise
            if response is None or response.get("access_token") is None:
                return "Access denied: response=%s" % response
            store_xero_oauth2_token(response)
            return redirect(url_for("index", _external=True))
        ```
        3. Call the Xero API like so:
        ```python
        @app.route("/accounting_invoice_read_all")
        @xero_token_required
        def accounting_invoice_read_all():
            code = get_code_snippet("INVOICES","READ_ALL")
        
            #[INVOICES:READ_ALL]
            xero_tenant_id = get_xero_tenant_id()
            accounting_api = AccountingApi(api_client)
        
            try:
                invoices_read = accounting_api.get_invoices(
                    xero_tenant_id
                )
            except AccountingBadRequestException as exception:
                output = "Error: " + exception.reason
                json = jsonify(exception.error_data)
            else:
                output = "Total invoices found:  {}.".format(len(invoices_read.invoices)
                )
                json = serialize_model(invoices_read)
            #[/INVOICES:READ_ALL]
        
            return render_template(
                "output.html", title="Invoices",code=code, output=output, json=json, len = 0, set="accounting", endpoint="invoice", action="read_all"
            )
        ```
        
        It is recommended that you store this token set JSON in a datastore in relation to the user who has authenticated the Xero API connection. Each time you want to call the Xero API, you will need to access the previously generated token set, initialize it on the SDK `client`, and refresh the `access_token` prior to making API calls.
        
        ### Token Set
        | key | value | description |
        | --- | --- | --- |
        | id_token: | "xxx.yyy.zzz" | [OpenID Connect](https://openid.net/connect/) token returned if `openid profile email` scopes accepted |
        | access_token: | "xxx.yyy.zzz" | [Bearer token](https://oauth.net/2/jwt/) with a 30 minute expiration required for all API calls |
        | expires_in: | 1800 | Time in seconds till the token expires - 1800s is 30m |
        | refresh_token: | "XXXXXXX" | Alphanumeric string used to obtain a new Token Set w/ a fresh access_token - 60 day expiry |
        | scope: | ["email", "profile", "openid", "accounting.transactions", "offline_access"] | The Xero permissions that are embedded in the `access_token` |
        
        Example Token Set JSON:
        ```
        {
          "id_token": "xxx.yyy.zz",
          "access_token": "xxx.yyy.zzz",
          "expires_in": 1800,
          "token_type": "Bearer",
          "refresh_token": "xxxxxxxxx",
          "scope": ["email", "profile", "openid", "accounting.transactions", "offline_access"]
        }
        ```
        
        ---
        ## Custom Connections
        
        Custom Connections are a Xero [premium option](https://developer.xero.com/documentation/oauth2/custom-connections) used for building M2M integrations to a single organisation. A custom connection uses OAuth 2.0's [`client_credentials`](https://www.oauth.com/oauth2-servers/access-tokens/client-credentials/) grant which eliminates the step of exchanging the temporary code for a token set.
        
        To use this SDK with a Custom Connections:
        ```python
        # -*- coding: utf-8 -*-
        import os
        from functools import wraps
        from io import BytesIO
        from logging.config import dictConfig
        from flask import Flask, url_for, render_template, session, redirect, json, send_file
        from flask_session import Session
        from xero_python.accounting import AccountingApi, ContactPerson, Contact, Contacts
        from xero_python.api_client import ApiClient, serialize
        from xero_python.api_client.configuration import Configuration
        from xero_python.api_client.oauth2 import OAuth2Token
        from xero_python.exceptions import AccountingBadRequestException
        from xero_python.identity import IdentityApi
        from xero_python.utils import getvalue
        import logging_settings
        from utils import jsonify, serialize_model
        
        dictConfig(logging_settings.default_settings)
        
        # configure main flask application
        app = Flask(__name__)
        app.config.from_object("default_settings")
        app.config.from_pyfile("config.py", silent=True)
        
        # configure persistent session cache
        Session(app)
        
        # configure xero-python sdk client
        api_client = ApiClient(
            Configuration(
                debug=app.config["DEBUG"],
                oauth2_token=OAuth2Token(
                    client_id=app.config["CLIENT_ID"], client_secret=app.config["CLIENT_SECRET"]
                ),
            ),
            pool_threads=1,
        )
        
        # configure token persistence and exchange point between app session and xero-python
        @api_client.oauth2_token_getter
        def obtain_xero_oauth2_token():
            return session.get("token")
        
        @api_client.oauth2_token_saver
        def store_xero_oauth2_token(token):
            session["token"] = token
            session.modified = True
        
        @app.route("/get_token")
        def get_token():
            try:
                # no user auth flow, no exchanging temp code for token
                xero_token = api_client.get_client_credentials_token()
            except Exception as e:
                print(e)
                raise
            # todo validate state value
            if xero_token is None or xero_token.get("access_token") is None:
                return "Access denied: response=%s" % xero_token
            store_xero_oauth2_token(xero_token)
            return redirect(url_for("index", _external=True))
        
        @app.route("/accounting_invoice_read_all")
        @xero_token_required
        def accounting_invoice_read_all():
            code = get_code_snippet("INVOICES","READ_ALL")
        
            #[INVOICES:READ_ALL]
            accounting_api = AccountingApi(api_client)
        
            try:
                invoices_read = accounting_api.get_invoices('')
            except AccountingBadRequestException as exception:
                output = "Error: " + exception.reason
                json = jsonify(exception.error_data)
            else:
                output = "Total invoices found:  {}.".format(len(invoices_read.invoices)
                )
                json = serialize_model(invoices_read)
            #[/INVOICES:READ_ALL]
        
            return render_template(
                "output.html", title="Invoices",code=code, output=output, json=json, len = 0, set="accounting", endpoint="invoice", action="read_all"
            )
        ```
        
        Because Custom Connections are only valid for a single organisation you don't need to pass the xero-tenant-id as the first parameter to every method, or more specifically for this SDK xeroTenantId can be an empty string.
        
        > Because the SDK is generated from the OpenAPI spec the parameter remains. For now you are required to pass an empty string to use this SDK with a Custom Connection.
        
        ---
        
        ## App Store Subscriptions
        
        If you are implementing subscriptions to participate in Xero's App Store you will need to setup [App Store subscriptions](https://developer.xero.com/documentation/guides/how-to-guides/xero-app-store-referrals/) endpoints.
        
        When a plan is successfully purchased, the user is redirected back to the URL specified in the setup process. The Xero App Store appends the subscription Id to this URL so you can immediately determine what plan the user has subscribed to through the subscriptions API.
        
        With your app credentials you can create a client via `client_credentials` grant_type with the `marketplace.billing` scope. This unique access_token will allow you to query any functions in `AppStoreApi`. Client Credentials tokens to query app store endpoints will only work for apps that have completed the App Store on-boarding process.
        ```python
        # configure xero-python sdk client
        api_client = ApiClient(
            Configuration(
                debug=app.config["DEBUG"],
                oauth2_token=OAuth2Token(
                    client_id=app.config["CLIENT_ID"], client_secret=app.config["CLIENT_SECRET"]
                ),
            ),
            pool_threads=1,
        )
        
        try:
            # pass True for app_store_billing - defaults to False if no value provided
            xero_token = api_client.get_client_credentials_token(True)
        except Exception as e:
            print(e)
            raise
        
        app_store_api = AppStoreApi(api_client)
        
        subscription = app_store_api.get_subscription(subscription_id)

        You should use the subscription data to provision user access/permissions to your application.
        ### App Store Subscription Webhooks
        
        In additon to a subscription Id being passed through the URL, when a purchase or an upgrade takes place you will be notified via a webhook. You can then use the subscription Id in the webhook payload to query the AppStore endpoints and determine what plan the user purchased, upgraded, downgraded or cancelled.
        
        Refer to Xero's documenation to learn more about setting up and receiving webhooks.

        ## API Clients
        You can access the different API sets and their available methods through the following:
        
        ```python
        accounting_api = AccountingApi(api_client)
        read_accounts = accounting_api.get_accounts(xero_tenant_id)
        asset_api = AssetApi(api_client)
        read_assets = asset_api.get_assets(xero_tenant_id)
        # ... all the API sets follow the same pattern
        ```
        ---
        ## Helper Methods
        
        Once you have a valid Token Set in your datastore, the next time you want to call the Xero API simply initialize a new `client` and refresh the token set.
        
        ```python
        # configure xero-python sdk client
        api_client = ApiClient(
            Configuration(
                debug=app.config["DEBUG"],
                oauth2_token=OAuth2Token(
                    client_id=app.config["CLIENT_ID"], client_secret=app.config["CLIENT_SECRET"]
                ),
            ),
            pool_threads=1,
        )
        
        # configure token persistence and exchange point between app session and xero-python
        @api_client.oauth2_token_getter
        def obtain_xero_oauth2_token():
            return session.get("token")
        
        @api_client.oauth2_token_saver
        def store_xero_oauth2_token(token):
            session["token"] = token
            session.modified = True
        
        # get existing token set
        token_set = get_token_set_from_database(user_id); // example function name
        
        # set token set to the api client
        store_xero_oauth2_token(token_set)
        
        # refresh token set on the api client
        api_client.refresh_oauth2_token()
        
        # call the Xero API
        accounting_api = AccountingApi(api_client)
        read_accounts = accounting_api.get_accounts(xero_tenant_id)
        ```
        
        A full list of the SDK client's methods:
        
        | method | description | params | returns
        | --- | --- | --- | --- |
        | api_client.`oauth2_token_saver` | A decorator to register a callback function for saving refreshed token while the old token has expired | token_saver: the callback function accepting `token` argument | token_saver to allow this method be used as decorator |
        | api_client.`oauth2_token_getter` | A decorator to register a callback function for getting oauth2 token | token_getter: the callback function returning oauth2 token dictionary | token_getter to allow this method be used as decorator |
        | api_client.`revoke_oauth2_token` | Revokes a users refresh token and removes all their connections to your app | N/A | empty OAuth2 token |
        | api_client.`refresh_oauth2_token` | Refreshes OAuth2 token set | N/A | new token set |
        | api_client.`set_oauth2_token` | Sets OAuth2 token directly on the client | dict token: standard token dictionary | N/A |
        | api_client.`get_oauth2_token` | Get OAuth2 token dictionary | N/A | dict |

        ## Usage Examples
        ### Accounting API
        ```python
        from xero_python.accounting import AccountingApi
        from xero_python.utils import getvalue
        
        accounting_api = AccountingApi(api_client)
        
        # Get Accounts
        read_accounts = accounting_api.get_accounts(xero_tenant_id)
        account_id = getvalue(read_accounts, "accounts.0.account_id", "")
        
        # Get Account by ID
        read_one_account = accounting_api.get_account(xero_tenant_id, account_id)
        
        # Create Invoice
        # get contact
        read_contacts = accounting_api.get_contacts(xero_tenant_id)
        contact_id = getvalue(read_contacts, "contacts.0.contact_id", "")
        # get account
        where = "Type==\"SALES\"&&Status==\"ACTIVE\""
        read_accounts = accounting_api.get_accounts(

        ## Running Test(s) in Local
        For Running Test cases PRISM Mock Server needs to be started in the local machine.
        Steps to Run Test(s)
        * Install PRISM from npm using the command:  **npm install -g @stoplight/prism-cli**
        * Verify Installation: **prism --version**
        * Navigate to **tests--> utils--> ** folder in the terminal
        * Execute the script **./start-prism.sh**
        * This will start the PRISM Server in Local
        * Run **pytest** to run the Python test cases.
