Usage

Lightning Flow Scanner App integrates the Lightning Flow Scanner as a UMD module within Salesforce, enabling scanning of flow metadata for 20+ issues such as hardcoded IDs, unsafe contexts, inefficient SOQL/DML operations, recursion risks, and missing fault handling.

For details about all available rules, their default severities, and configuration options, visit the Flow Scanner Documentation.

Configuration

While no configuration is required, Admins can define default severities, expressions, or disabled states for scan rules using the ScanRuleConfiguration__mdt custom metadata type. These overrides apply globally for all users in the org, but individual users can still adjust severities or disable rules locally in the browser — those changes only persist for their current session. For a more on configurations, review the documentation.

1. Go to Setup → Custom Metadata Types → ScanRuleConfiguration → Manage Records
2. Click New and set the following fields:

• Rule Name — must match the rule’s API name (e.g., FlowName)
• Severity — Error, Warning, Info, or Note
• Expression (optional) — e.g., [A-Za-z]+_[0-9]+
• Disabled — check to turn off the rule globally

1. Once saved, the Flow Scanner App automatically applies these overrides at load time.
