Xero Ruby OAuth 2.0 App

This Ruby On Rails project demonstrates how to use the https://github.com/XeroAPI/xero-ruby SDK.

Its purpose is to speed up new ruby devs looking to build amazing applications with the data of users of the Xero Accounting platform: https://xero.com/. Secure authentication is setup using industry standard OAuth2.0. Access/Refresh tokens fuel authorized api calls.

Note: this project was built using:

• ruby 3.3.0
• Rails 6.0.6.1

git clone [email protected]:XeroAPI/xero-ruby-oauth2-app.git
cd xero-ruby-oauth2-app
bundle install
yarn

Configure with your credentials

• Create a free Xero user account
• Login to your Xero developer /myapps dashboard & create an API application

Create a .env in the root of your project directory or replace the env.sample

CLIENT_ID=...
CLIENT_SECRET=...
REDIRECT_URI=...

Start your server

bundle exec rake db:create db:migrate
yarn
rails s

By default rails runs on port 3000. Make sure you have in your /myapps dashboard 'http://localhost:3000/callback' or specify the port with rails s -p 8080 etc.

Important structure

The project shows a strategy to effectively leverage the xero-ruby SDK. It is best documented by cloning/running the app but here are a few tips to quickly understanding the structure if you are not familair with Rails.

Routes

• config/routes.rb will give a great picture of this apps functionality

User model

• One table :users - utilizes super basic authentication.
• A JSON column :token_set that stores the entire token_set returned from the auth flow
• A string column active_tenant_id that references the actively selected tenant/org

Application Controller

Bulk of the auth flow logic. This uses a few helpers but shows how to handle the full authentication flow, refresh a token, disconnect an org, and even change which org you want to make api calls to.

• callback
• refresh_token
• change_organisation
• disconnect

Application Helper

This includes some helpers that showcase how to decode the individual pieces of the token_set and show the multiple ways you can setup the xero_client, etc..

• token_expired
• id_token
• access_token
• current_user
• xero_client
• accounting_api
• authorization_url
• latest_connection

Debugging

• put -fail or binding.pry in your code for an interactive brower or terminal shell where you can inspect the current request, manipulate results and see where your code went wrong ;)

Contributing

You are very welcome to add/improve functionality - we will continue to make improvements that show more complex API usage like filter/sorting, paginating, and will add more CRUD workflows as new API sets are added to the ruby-sdk. Please open an issue if something is not working correctly.
