I have a bit of a strange use-case, so I don't suppose there's an easy way to do this by the nature of how interceptors work within Apollo. But I am scratching my head to see if it's easy enough to identify the same request from within an ApolloInterceptor and a HttpInterceptor to then be able to essentially collate all the information Apollo has for that GraphQL call. An ApolloInterceptor will supply a UUID for a call, but there's no way to propagate that to an HttpInterceptor right?

[mbonnin]

The ExecutionContext is passed down to HttpInterceptor now IIRC. Let me check

[mbonnin]

Yup, it's in there: https://apollographql.github.io/apollo-kotlin/kdoc/apollo-api/com.apollographql.apollo.api.http/-http-request/execution-context.html

[mbonnin]

So what you could do is pass the uuid in there.

[mbonnin]

Create an ApolloInterceptor that adds a custom ExecutionContext containing the uuid and that will be available in the HttpInterceptor

[mbonnin]

Alternatively, you could also use a HTTP header for that. It's a bit weirder but that would work as well. Your HttpInterceptor could strip it.

[Ed Holloway-George]

Ah I'm thick, I tried the header approach but was under the belief it'd be the HttpInterceptor sending it to the ApolloInterceptor and not the other way around. In hindsight, that doesn't make as much sense

Thanks Martin 🥰

ExecutionContext looks like exactly what I need

ExecutionContext worked perfectly. Thanks for the hint 💪
