Paddle Demultiplexer

Paddle only allows one webhook URL, so we need a demultiplexer.

How it works

This tool will run on a free tier Google AppEngine instance and listen for webhooks. Once it receives a webhook it will look into its Body and redirect the payload to a specified URL based on subscription_plan_id (also known as Plan ID). The path is not configurable, meaning that all your apps must have the same URL structure for Paddle webhooks (e.g. /paddle/webhook).

This tool doesn't validate the payload, it's up to your app to do that.

Setup

• Create a new Google AppEngine project, let's call it your_project.
• Edit main.go and enter your webhook URLs along with their matching Plan IDs. You can find your Plan IDs here.
• Edit the Makefile and set PROJECT to your_project.
• Type make deploy.
• Tell Paddle to send webhooks to https://your_project.appspot.com/your_webhook_path.
