We would like to be able to send an SMS to some users of our service, and within that SMS the user would have a link that will directly open a chat session with one of our agents.
The point is that user, in most cases, would not have visited our website before. He / She would have been provisioned in our Zendesk user database by "create user" ZEndesk API before. And of course we would like to associate that first chat session with that user being prior created by API.
Is this possible ? How to do that and how to create that link in the SMS that would contain the zendesk User Id in order it will be automatically recognized in it first chat session ?
