Use metadata to carry your own application context through the task lifecycle.

​
Attach metadata

const task = await mynth.image.generate({
  prompt: "Packaging concept for a botanical tea brand",
  model: "google/gemini-3.1-flash-image",
  metadata: {
    requestId: "req_123",
    userId: "usr_123",
    campaign: "spring-launch",
  },
});
Mynth returns that metadata in:
  • the full task object
  • webhook payloads
This is useful for mapping Mynth tasks back to your own jobs, users, orders, or records.

​
Metadata limits

Metadata can contain nested objects and arrays. The maximum payload size is 2 KB.
