ForAllValues:ArnLikeIfExists

compares a list of ARNs in a request to a list of ARN patterns in your policy. The policy values can include asterisks (*) to match multiple characters and question marks (?) to match a single character within an ARN segement. Wildcards cannot be used to span ARN segment, so the partition, service, region, account, and resource must all be present in your policy value, even if they are all wildcards. The comparison is case sensitive.

To match a request, the context key can be absent, but if it is present, all of the ARNs in the request must match at least one of the ARN patterns in your policy.

You can use policy variables in the value of this operator.

Warning

ForAllValues:ArnLikeIfExists is actively confusing. Any operator starting with ForAllValues ignores IfExists — it is not evaluated against the entire array, only against a single value at a time inside the ForAllValues loop. Use ForAllValues:ArnLike instead so your coworkers don't hate you.
