Shopify Webhooks in AWS

This details how to handle Shopify webhooks using AWS API Gateway, Lambda, and SQS. Read the complete blog post at https://rewind.io/blog/handle-shopify-webhooks-without-a-server/ first.

Why

Shopify webhooks are useful for getting information from Shopify in realtime. However for popular apps with thousands of users, these webhooks can overwhelm a system. For example, when a Shopify store imports data from another system (when syncing inventory numbers for ex.), Shopify can send out thousands of webhooks that the app must respond to within 3 seconds.

This solution uses AWS infrastructure to handle the webhooks. It uses AWS Workers to process the webhooks by posting the data from an SQS queue to http://localhost.

Requirements

You need an AWS account to implement this solution.

Setup

Follow the instructions in this blog post to setup AWS to handle the webhooks with a combination of AWS API Gateway, Lambda, SQS, and ElasticBeanstalk workers.

Sample Rails Files

In this repository we have two sample files that you can use to process the webhooks.

You'll need a rails application that has the ShopifyAPI gem in it. The two files provided are:

app/controllers/shopify_webhook_controller.rb
config/routes.rb

Create a rails application first. Then use these two files to process the webhooks. Enter your own logic in shopify_webhooks_controller.rb to do whatever you want with the webhook data.
