Evaluate the message against a rule or validation condition.
Messaging Channels
Invalid Message Channel
Move messages that are structurally or semantically invalid to a dedicated channel for inspection instead of repeatedly failing normal processing.

How Invalid Message Channel works
A rule decides whether a message continues through the normal flow or is removed from it.
Candidate message
Invalid Message Channel
Accepted
Ignored / isolated
Apply Invalid Message Channel to separate useful messages from unwanted or invalid ones.
Forward accepted messages and explicitly handle the rejected path.
What this pattern helps you decide
Move messages that are structurally or semantically invalid to a dedicated channel for inspection instead of repeatedly failing normal processing.
What happens when processing fails or the same message is delivered twice?
Where does state, correlation or routing configuration live?
How will operators trace the message and understand the decision path?
Where you may see it
- Validation-failure queue
- Logic Apps exception path
- BizTalk suspended-message handling
How the analyzers can surface it
- Validation policies
- Error and invalid-message routes
Pattern detection is contextual. GateSift should present these as architectural signals, not claim a pattern is implemented solely because one policy statement or adapter exists.
