Get SQS Queue Name from existing queue ARN in CloudFormation

Question

I have an SQS Queue ARN as an input to my CloudFormation template, How do I reference Queue Name or URL from Queue ARN?

In other words, how do I get a CloudFormation Logical Queue from the ARN?(so that I can use GetAtt to reference all the attributes)

How is the queue being created? Can you export its name from cloudformation when you create it, then reference it in your other template docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/… — TheClassic
@TheClassic Let's say I do not own the queue, I only am given the Queue ARN — Abhishek

Assuming you can't pass in the name from whatever is creating the queue, then you can get the queue name from the arn. Use Fn::Split to split the arn on colons. Then use Fn::Select to select the last string in the list. This will be something like

{ "Fn::Select" : [ "5", { "Fn::Split": [":", {"Fn::Sub": "QueueArn"}]}] }

See https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/intrinsic-function-reference.html for a full list of the functions you can use.
