After submitting a task, use the unified query endpoint to check progress and retrieve results:
Save generation.id and query the task until it reaches a terminal state. For production integrations, provide callback_url and verify the webhook signature before accepting the result.
Manage the secret used to verify generation webhook signatures. Callback URLs are supplied when you create each generation.
Callback URL per generation.
