Testing Omise WebHooks in test environment


This blog post is translated from OmiseのWebhookをテスト環境で試すためのアプリを用意しました by *\Akira Narita*, Lead Developer at Omise.

What is Omise WebHooks?

WebHooks are simple HTTP POST requests that will be triggered from Omise servers whenever an action has been performed either through the API, or through the dashboard.

Whenever you create a charge on the test dashboard, you will be notified through Webhooks. Here’s an example.

  "object": "event",
  "id": "evnt_test_56vp5pfwjf1fqjn4ryy",
  "livemode": false,

You can add a WebHook endpoint from your dashboard.

How to add webhooks on the dashboard

Follow these steps

  1. Select the Webhooks menu from the left hand side of your Omise dashboard, and click on Edit.
  2. Update your preferred endpoint (receiver URL) and click Update.

When the event object occurs, a POST request will be sent to your endpoint. Remember that the URL specified must be HTTPS and must use a valid SSL certificate. Please refer to our WebHooks documentation for more information.

Getting started

For easy explanation, we created omise-webhook. The application is created using Sinatra, and we use ngrok to create the HTTPS URL for the endpoint. This allows us to keep JSON’s data which is sent from Omise WebHook as log when you start the app from your local machine.

The application works in environments which has git clone, homebrew, homebrew-cask, ruby v2.3.1. Please make sure you have applied the settings below before starting.

git clone git@github.com:akinrt/omise-webhook.git
cd omise-webhook

# bundlerをインストール
gem install bundler

# 必要なgemのインストール
bundle install --path vendor/bundle

# ngrokのインストール
brew cask install ngrok

# .envをつくる
touch .env

Your Omise secret key is required for .env, you can find it in your dashboard.

# .env

Start application and ngrok, then confirm the HTTPS URL used for endpoint.

# Start application
bundle exec ruby app.rb

# Start ngrok in a new window
ngrok http 3000

Please use the HTTPS URL created from ngrok as endpoint.

ngrok link sample

This application will receive Omise webhook at /omise/webhook. You can copy the URL from ngrok and add it to your Omise dashboard.

Adding a webhooks URL

Whenever you create a charge or any other events, this application will save JSON object to omise-webhook/log/api/event/, where you can confirm the response.

As always, we’re more than happy to assist you. For questions or feedback, please send an email to support@omise.co
