Callbacks for questions

Get the answer to a question POSTed to your own endpoint, signed, with your state echoed back, so serverless code doesn't have to wait.

• callbackUrl. Send it with a question and EmitKit POSTs the answer (event.answered), or the expiry (event.expired), to your endpoint, signed the Standard Webhooks way with your project’s callback secret (Settings → API keys). Failed deliveries are retried for about 16 hours with the same webhook-id. See Callbacks.
• resume. Up to 65,536 characters of your own state, sent back as is in the callback and GET /v1/events/{id}, so a serverless handler can carry on without a database.
• Delivery status. GET /v1/events/{id} shows callback: attempts, the last status and when it was delivered.
