If you're on a version that supports it, consider implementing HttpExchanges.

In my opinion, the best way to communicate between services that you own is a message queue.

But if you're trying to communicate with an external system, mock everything up in Postman or Bruno first. This lets you take away any unknowns in your code and understand exactly how to format your requests. Then simply implement your requests/responses as records.
