The documentation portal is undergoing maintenance. During this period, you can't create any new user credentials. If you do, you'll need to recreate the user credential after the maintenance period ends.
A gateway splits a sequence flow into multiple branches or merges multiple branches into a sequence flow. Gateways operate in pairs. One gateway defines the branches that the workflow data can follow. Another gateway restores the branches to a single sequence flow. You can add a condition to the sequence flow that starts each branch. The Data Integration Service uses the condition values to identify the branches that the workflow data follows.
