Are there any rate-limits to consider for my chatbot? (will have to handle quite much volume)

I also use the Cisco Enterprise Chat & Mail API. There it is documented that webhooks, that are not confirmed, will be resent several times.https://pubhub.devnetcloud.com/media/enterprise-chat-and-email/docs/guides/interaction-api-developer-guide/d2/...

thank you, I just saw this in the documentation as well. However it is not documented if those who fail are resent?
