Find your GCP Project ID
Your Project ID is the permanent, unique identifier of the Google Cloud project StackOne connects to. The long audio synthesis and operations actions use it. Use the Project ID, not the project name or project number.

- Paste it into the GCP Project ID field in StackOne Hub.
- Format: 6 to 30 lowercase letters, digits or hyphens, starting with a letter
- Example:
