SNS message body filter functionality logic

Question

We need to understand how the SNS message body filter functionality is working. we are having one use case like our project SQS consumer will provide the SNS filter policy after that we need to subscribe to SNS with filter policy to test it. is there any logic available in AWS SDK to test the SNS filter policy without subscribe to SNS.

Basically we are expecting is there any functionality available to test the SNS filter policy before subscribe to SNS like regular expression validation.

Answer

Hello,
Unfortunately, there is no such functionality currently, where it is possible to test the SNS filter policy before subscribe to SNS. In order to test a filter policy, you can create a test topic, with a test subscription, then set a test filter policy to that subscription. If your test results satisfied you, promote that configuration to production.
