Don’t your users just love it when they see this on their screen?

The fun really starts when you get this email in your inbox.

You could certainly take the time and effort to add a bunch of decision elements and recreate all of your validation rules in your flow.  I bet it would be even more exciting trying to keep all of that maintained.  

Wouldn’t it be nice if your Flows could check for and trap Validation Rule failures, missing required fields, lookup filter violations, text overruns and Duplicate Rule failures?

Well now they can with this simple Check Validation flow action.  

Before you attempt a Create Records or Update Records element in your Flow, add this simple Flow Action and pass it a single record or a collection of records.

This action will check your record(s) and let you know if there would be any Validation Rule errors, field size overruns, lookup filter violations, missing required fields and Duplicate Rule errors if you tried to create or update the record(s).

All this is done before you try to do something that would cause the Flow to fail with an unhandled fault.  You get to determine what to do next and what information you want to present to your user.

You can also use this action as part of your Fault Paths. Instead of just handling the fault without knowing exactly what it is, you can get the error(s) that caused the fault and act on them as you see fit.

In this Flow, a Toast Message will be displayed with any errors and the User will be given a choice of whether or not they want to Try Again or Exit.

You can specify which field from your record you want to include in the error messages to help identify which record(s) failed.

The action returns an isError boolean value along with a text message of the individual errors.  

Validation Rule Failures

Missing Required Field Error

Text Field Size Error

You can set an optional input attribute to have the Validation Checker review all Duplicate Rules when you are providing records to be inserted.

You can even specify an optional input attribute to use this action instead of the Create Records or Update Records to actually perform the inserts and updates if no errors are generated.  If you perform a successful insert of new records, the new record ID(s) will be returned by the action.

Take control of your automations and no more worrying about Flows crashing when User provided values won’t pass Validation Rules or other input errors.


  • If there are multiple types of errors, only one type of error will be returned.
  • If any Text fields are over their size limit, only those errors will be returned.
  • If any Validation Rule fails, all Validation Rule failures will be returned.
  • If any Required Fields are missing, only those errors will be returned.
  • If any Lookup field values violate the defined Filter, only those errors will be returned.
  • If specified in the attributes, Duplication Rules will be checked on new records.
  • Fields over their size limit are handled first, followed by Validation Rules, followed by Required Fields, followed by Filter violations, optionally followed by Duplicate Rule checks.
