App Builder Authentication

I'm trying to set up Adobe I/O API for syncing data with Adobe Events using App Builder. I've successfully created a project and a workspace in the Developer Console.

When I connect my local Adobe Commerce setup to this workspace, the event data syncs properly. However, when I attempt the same connection from my development environment on Adobe Commerce Cloud, I receive the following error:

**Event publishing failed: Error code: 403; reason: Forbidden**
```json
{
"error": {
"code": "Forbidden",
"message": "Client ID is invalid",
"details": {
"error_code": "403003"
}
}
}
```

Can someone assist me with this issue?
