Actually, turns out I shouldn't use that on launch anyway! For now I'm abstracting the few calls to the SDK into my own object under a Swift "namespace" (an enum).
This file will probably change a lot in the near future, but for now it gives me hooks to call on sign in/out.

The RevenueCat SDK was throwing warnings about not finding an offering, so I created one. The docs say they are optional, but I figured why not.

Since I'm working in a hybrid app most of the UI is rendered on the web.
So I can send a JavaScript message to the client when the web-based purchase button is clicked. This Stimulus controller grabs the iOS plan identifier to pass along to RevenueCat.

Back in iOS I can extract the plan identifier from the JavaScript message and make a purchase directly.

Oh hey! I think something might be working!
Time to revisit the section in the docs on integrating with the sandbox.

Progress! After setting up the StoreKit Configuration File I was able to make a purchase in the simulator. I had to copy over all the details from App Store Connect to the config.

Up next is integrating the webhooks from RevenueCat into my Rails app. Then I can associate iOS purchases with users in the Rails database.
But first… lunch!

OK, back at it!
Does RevenueCat only support a single webhook URL? How are we expected to manage development vs. production environments?

Progress progress!
I now have a small Rails controller that handles authorization and kicks off a background job. Now I can unit test the actual sync logic in a PORO and not deal with integration/controller tests.

From RevenueCat's recommendation, the webhook kicks off a single GET request to their REST API to sync.
Here's a rough first pass at extracting an active subscription and assigning it to Pay. An official RevenueCat Pay integration might make sense.

That's all for today!
I'll continue to update this thread when I continue working on the integration.
Until then, all the Rails code is pushed to this branch. Enjoy your weekend everyone.

Back at integrating with my Rails app!
The more I think about this the more confused I get. Why is it simpler to have a single method/class do EVERYTHING when we are already getting the "diff" with each webhook?

A little weekend hacking today on the RevenueCat integration!
Thanks to for the hints and ideas, I've implemented a first pass of the webhook workflow. This kicks off a "sync" job for subscriptions.

No problem. This feels like an area of Rails that there’s little to no articles about. I’m excited to start kicking it off.
