Mark a callback done

POST
/callbacks/{id}/complete
import MoreVoice from "@morevoice/sdk";


const mv = new MoreVoice(); // MOREVOICE_API_KEY from the environment


const callback = await mv.callbacks.complete("cb_7Hk2Lm9Qp", {
  note: "Reached by email",
});
console.log(callback);

Closes an open callback that was resolved another way (409 while it is on a call). Emits callback.completed. Needs a live key.

Try it in the API playground with a test-mode key.
