How to smoothly migrate webhook endpoints for a large app?

[marcreese]

Hello,

I have a BIG running App on the store and I am planning to ship a whole new version (PHP to NodeJS app).

For some reasons, I need to change the domain where the app will be hosted.

So when ready, I will have to update the app url and all the different whitelisted urls in the Shopify partner admin within the app config.

But I have some trouble finding a clean and safe solution to migration the already registered webhooks for all my customers (different shops) to the new domain.

Ex: domain1.com/webhook/orders-create to domain2.com/webhook/orders-create

What would be the best way to make sure this transition will be smooth without asking all my customers to get into the /auth process ?

FYI: I dont have offline tokens for my customers, online online that expire under 24h

Thank you a lot 🙏
