Unfortunately Apple only allow developers to add a single domain for their In App Payments (IAP) web hooks, cause you know, who needs a development environment?
This project is a single Lambda that will redirect to a given URL depending on whether or not the webhook came from Apple's production environment. It exposes a single endpoint /api/redirect that can redirect to two seperate environments.
This project has been configured to run on Vercel all you need to do is press the button below to clone this repository and deploy under your own Vercel account.
Pressing the above button will also create two environment variables, if you'd prefer not to use the automatic deployments then you will need to manually add the following variables:
DEVELOPMENT_REDIRECT: your development API endpointPRODUCTION_REDIRECT: your production API endpoint
Once deployed update your webhook URL in App Store Connect to <domain>/api/redirect.
