Short answer – nope!
Long answer – still nope! You will have 4 records – 2 in Staging (1 Source record, 1 Destination record) and 2 in Production (1 Source record, 1 Destination record).
Each of these 4 records has its own respective ID. Every node on our network maintains this format. What this means is that when you send a message to an integration partner, that message should contain their Destination ID as well as your Source ID as a means of tracking where the data was generated and where it was sent to. Similarly, the messages you receive will contain your Destination ID and a Source ID indicating which of your connections that data came from.
Source and Destination IDs are auto-generated for each Source and Destination record. To find them, go to the Subscriptions page for your destination or source, there should be an ID link next to the name of your organization that you can click to display the ID.
