My demand still is on "Review in progress" since a month now

Community Management API access requests that require vetting are reviewed based on a survey that is generated in the LinkedIn Developer Portal. The survey must be completed within 21 days from when it is triggered. If it is not submitted in time, or if additional information requested by the review team is not provided within 21 days, the request is marked as Insufficient Details and the application may be closed.

When that happens, a Reapply option appears in the Developer Portal so the same product can be requested again without creating a new application.

For a request that has shown Review in progress for many weeks:

1. Sign in to the LinkedIn Developer Portal.
2. Open My Apps → [Your App] → Products and check the Community Management API product status.
3. Look for any vetting survey or follow-up questions and ensure all required information has been submitted.
4. If the request shows Insufficient Details or similar and the Reapply button is available, use it to resubmit the request with complete information.
5. If no survey or reapply option is visible and the status remains stuck, contact Developer Support with your app details to request a status update.

Also note that Community Management API Development tier is the default tier and is intended for building and testing integrations within twelve months. Standard tier must be requested separately once the integration is ready for production.
