# Common Forge REST API Request errors

## Client id not whitelisted
```
Status: 403 Unauthorized
Body: {fault.name} - The client_id specified does not have access to the api product
```
If you see such an error, it is likely that the client id you used is not authorized to use the Design Automation for Revit's private beta service. Please [contact us](mailto:revit.io.support@autodesk.com) to get your client id whitelisted or use the one that is already whitelisted. Also, refer to our [Getting Started on Forge](Forge.md#creating-a-forge-app) documentation.

If you are already using a whitelisted client id and if you still see this error, please contact us at [revit.io.support@autodesk.com](mailto:revit.io.support@autodesk.com).
