Spot the Difference lets you define rules on mismatches between user-supplied inputs and data returned by registries or other service providers used in your process. For selected fields, the platform compares the user value to the provider value and exposes the outcome (match/mismatch/missing) as a condition you can use in decision logic.

These conditions can trigger next steps such as flagging a case for review, requesting a correction, or stopping progression until a conflict is resolved - without custom scripting. Each comparison stores both values, the source, and the evaluation result on the case, so reviewers can see exactly what differed and why a rule fired. You can reuse the same discrepancy checks across processes to keep policies consistent and reduce ad‑hoc handling.
