inbox_key_target_invalid
HTTP status: 422
What happened
The API key cannot be bound to this inbox. The inbox is missing, deleted, belongs to another organization, or uses a different mode from the key.
How to fix
Choose an active inbox in the same organization and the same mode as the key. A test key binds only to a test inbox.
