I'd be happy to lend my assistance for collaborating. I'm familiar with the Wolfram functionality around making HTTP requests, including the HTTPRequest and HTTPResponse expressions. I haven't used Shopify, but I have used WooCommerce and gotten my hands dirty in its code.

Sorry for the delay, I've had some personal issues to tend to. And when I do get back to this forum, I sometimes find it difficult to find what I need to respond to.

I've made progress using the REST API directly. My first app looks at recent orders and then applies a set of rules to add tags to the customer.

While this works, it is not pretty. I would much rather use ServiceConnect.

I've tried Googling for how to create a custom ServiceConnection. The only thing I've found was a 2017 Stack Exchange post.

But, it seems like a great deal of additional work for what I'm trying to do.

Does anyone know of other examples creating custom ServiceConnections?

Thanks.
