 ### Fetching Status Check Rules for External CI
 
-If you're consuming the `size_analysis.completed` webhook in your own CI, you can fetch the project's current status check rule config with `GET /api/0/projects/{organization_id_or_slug}/{project_id_or_slug}/preprod/size-analysis/status-check-rules/`. See the [Mobile Builds API reference](/api/mobile-builds/) for Size Analysis API documentation.
+If you're consuming the `size_analysis.completed` webhook in your own CI, you can fetch the project's current status check rule config from the [Size Analysis status check rules API](/api/mobile-builds/retrieve-size-analysis-status-check-rules-for-a-project/).
 
 Use this when you want external CI to evaluate the same thresholds that Sentry uses for Size Analysis status checks, without duplicating rule configuration outside Sentry. The API reference documents the response shape, filter operators, AND/OR grouping semantics, wildcard matching behavior, and invalid-filter handling.
