        authentication {
            header(HttpHeaderAuthentication)
        }
    }

Transitive dependencies

The SDK pulls in the following at runtime. You do not need to declare them manually.

Artifact	Version
`io.ktor:ktor-client-core`	3.0.3
`io.ktor:ktor-client-cio`	3.0.3
`io.ktor:ktor-client-content-negotiation`	3.0.3
`io.ktor:ktor-serialization-kotlinx-json`	3.0.3
`org.jetbrains.kotlinx:kotlinx-coroutines-core`	1.9.0
`org.jetbrains.kotlinx:kotlinx-serialization-json`	1.7.3
`org.slf4j:slf4j-api`	2.0.9

Deploy token

Generate a deploy token in your GitLab project under Settings > Repository > Deploy tokens. Grant the read_package_registry scope. Store the token in CI/CD as a masked variable (NEXUS_DEPLOY_TOKEN).

Verifying connectivity

Before writing any code, confirm your endpoint and API key work with a plain curl:

curl -s \
  -H "X-Nexus-API-Key: wxs_..." \
  https://your-service.westyx.dev/v1/sync

A valid response returns a JSON snapshot with your configs, secrets, and flags. An HTTP 401 means the key is wrong; HTTP 404 means the slug is wrong. To watch the live SSE stream:

curl -N \
  -H "X-Nexus-API-Key: wxs_..." \
  -H "Accept: text/event-stream" \
  https://your-service.westyx.dev/v1/stream

You should see event:resync arrive within a second. Press Ctrl+C to stop.
