Webhook Testing and Development Tools

3 posts · Aug 2011 – Jul 2014

What this trail covers

This feature thread tracks the development and enhancement of tools and strategies for testing and developing webhooks. Initial efforts focused on addressing the challenges of testing webhooks during development, particularly the need for a publicly accessible URL. This post introduces PostCatcher, a web application that generates unique URLs for receiving and examining POST requests, and LocalTunnel, a service that exposes local machine ports to the internet, allowing developers to use localhost.

All Shopify trails
  1. Kafka Producer Pipeline for Ruby on Rails - ShopifyIntroduced a Kafka producer pipeline for Ruby on Rails. Leveraged SysV message queues for reliable event buffering between Rails and a Go Kafka producer, ensuring data durability during Kafka downtime. Adapted the pipeline for Dockerized environments by introducing a TCP to SysV MQ proxy.
  2. Webhook Best Practices - ShopifyThis post details best practices for using webhooks, including when to use them (e.g., for event-driven actions, data not easily searchable via API), how to handle requests quickly to avoid timeouts (e.g., using Delayed Jobs in Rails), and strategies for recovering missing data after an outage (e.g., building a harness to re-feed data into webhook processing code). It also mentions the importance of registering only necessary webhooks and checking existing ones.
  3. Webhook Testing Made Easy - ShopifyIntroduced PostCatcher, a web application for generating unique webhook URLs and examining POST requests in real-time. Also introduced LocalTunnel, a Ruby gem and webapp that exposes local machine ports to the internet via a URL, simplifying webhook testing by allowing local development endpoints to be registered as webhook destinations.
