Hi, everyone!
Any suggestions/experience on how to employ contract testing for "long" consumer-provider chains, where the data is consumed by pacticipants that do not interact directly?

One simple example would be a chain with 3 pacticipants  `A <> B <> C`, where `B` is not using the `C` response, but it simply wraps it and forwards it to `A`.
That is:
• `A` is in the position to write meaningful interactions against `C`, (`A` "consumes" `C`'s response), but `A` interacts with `B`
• `B` interacts with `C` , but it has no requirements on the response (it treats it as an opaque payload), so cannot define meaningful interactions for `C` to verify.

Hey <@U070KDLQF97>, this page might be a start: <https://docs.pact.io/getting_started/what_is_pact_good_for#why-pact-may-not-be-the-best-tool-for-testing-pass-through-apis-like-bffs>

Is `B` a gateway or proxy Bogdan? What’s it’s role in the process?

`B` is providing access to a service (which `A` cannot access directly). All `B` is advertising is:
```{
    "results" : { ... }
}```
where the payload received from `C` is simply returned inside the `results` value.
