I need your help to understand, we have one environment for Salesforce and 2 environment for PureCloud( .com and .ie)
Currently, we have integration with .com and Salesforce and it works fine.
Can we also do a similar installed package for .ie and Salesforce. Will that work? Or Is there anything else that has to be done?
These articles should give you what you need. The one thing to keep in mind is that there is a 1:1 relationship between a Salesforce instance and a PureCloud org for API based integration features, namely Salesforce Email Routing and Campaign Management. These features require an Oauth client be configured, and there is only one Oauth client allowed per managed package, and only one managed package (of a specific type) can be installed per Salesforce instance (i.e. you cannot install two of the PureCloud for Salesforce managed package, as Salesforce does not support this configuration).
