Purpose

This PR fixes an inconsistency in how the project ID is propagated from platform-api to the gateway and Moesif.

Previously, REST API deployments used the internal project_uuid when populating the gateway.api-platform.wso2.com/project-id annotation, while Project Insights used the project handle (e.g. new-project) when filtering Moesif traffic. This caused Project Insights to show 0 traffic for APIs with existing traffic.

Changes:

  • Adds a second deployment annotation gateway.api-platform.wso2.com/project-handle and teaches the gateway analytics path to prefer it for Moesif, while keeping gateway.api-platform.wso2.com/project-id as the internal project UUID.
  • Leaves non-analytics UUID references unchanged (DB FK, project-id annotation, Metadata.ProjectID, import contract).

After this change,

  1. platform-api BuildAPIDeploymentYAML: stamps both annotations on deployment YAML

  2. gateway-controller: reads both → Metadata.ProjectID (UUID) + Metadata.ProjectHandle (handle)

  3. analytics emit (policy xDS / Envoy route metadata): project_id = handle (prefer project-handle)

  4. policy-engine → Moesif: metadata.projectId = handle ← matches Insights

📝 Walkthrough

Walkthrough

The API model now carries the project handle from repository retrieval through update validation and deployment metadata generation. Gateway transformation and route metadata prefer the project handle for analytics and fall back to the project ID.

Changes

Project Handle Propagation

Layer / File(s) Summary
API project handle retrieval and update preservation
platform-api/internal/model/api.go, platform-api/internal/repository/api.go, platform-api/internal/service/api.go, platform-api/internal/service/api_test.go, platform-api/internal/service/artifact_runtime_immutable_test.go
API carries a non-persisted ProjectHandle. GetAPIByUUID retrieves it from the associated project. UpdateAPI preserves it during runtime-artifact comparison. Tests cover matching and missing handles.
Deployment project annotations
common/constants/constants.go, platform-api/internal/utils/api.go, platform-api/internal/utils/api_test.go
Deployment YAML always includes the project ID annotation and includes the trimmed project-handle annotation when set. Tests cover both cases.
Gateway analytics project resolution
gateway/gateway-controller/pkg/models/runtime_deploy_config.go, gateway/gateway-controller/pkg/models/runtime_deploy_config_test.go, gateway/gateway-controller/pkg/transform/restapi.go, gateway/gateway-controller/pkg/transform/restapi_test.go, gateway/gateway-controller/pkg/policyxds/snapshot.go, gateway/gateway-controller/pkg/xds/translator.go
Gateway runtime metadata reads the project-handle annotation. Analytics route metadata prefers the project handle and falls back to the project ID. Tests cover the preference and fallback behavior.

Estimated code review effort: 3 (Moderate) | ~25 minutes

Merge Risk: 🔵 Low · up to af3d9

Project handles now take precedence over UUIDs for gateway analytics metadata. Directly imported APIs with a whitespace-only handle can lose their valid project association in analytics until the fallback handling is corrected.

The requirement is to send both to Moesif. AnalyticsProjectRef() currently replaces the UUID with the handle, which changes the meaning of the existing projectId attribute and could break existing dashboards/alerts and other consumers of that value.

Can we keep the existing projectId as the UUID and add the handle as a separate attribute instead? That would satisfy the requirement without changing existing semantics.

AnnotationProjectID = "gateway.api-platform.wso2.com/project-id"
// AnnotationProjectHandle is the user-facing project handle used for analytics
// (e.g. Moesif metadata.projectId). Prefer this over AnnotationProjectID when both are set.
AnnotationProjectHandle = "gateway.api-platform.wso2.com/project-handle"

ResolveImportProject still reads the dual-typed project-id annotation and passes it to a handle lookup, so control-plane artifacts with UUIDs would fail if they reach this path.

Since we now have a dedicated handle annotation, can the importer prefer the new key and fall back to project-id for older artifacts? This would also let us eventually make project-id consistently UUID-based and remove the current ambiguity.

// extractProjectHandleFromConfig reads the analytics-facing project handle annotation.

This change is a no-op here: the value is only passed to the REST route builder, which doesn’t use the project-id parameter. The actual Envoy metadata is stamped by the per-topic route builder, which still uses the original UUID-only extraction. WebSub would keep publishing the UUID while REST publishes the handle, making the same Moesif attribute mean different things by API type.

follow-up: MCP/LLM APIs currently get no project attribute, and MCP would drop annotations during conversion anyway. We should confirm whether those API types are in scope.
