How to do a handshake with SNS Subsbription?

Hi @deepak.shaw ,
I tried the same last week as well, and unfortunately didn’t make it work. The ultra tasks require either a Bearer token, or a basic auth if the bearer token is not set. I failed to make subscriptions using either of the authentication.

I wasn’t able to find a way setting bearer token in the SNS subscription (maybe it would be a question or feature request for AWS SNS team). They do provide a way to include basic auth credentials inside the ‘endpoint’ request parameter. But as I have tested, if the username is an email address, it won’t work since it will break the url format.

For now, I would suggest to subscribe the SQS queue to the SNS topic, and use a SQS Consumer Snap to consume the message and trigger a downstream pipeline.

Also, if you find any other solutions, please let me know.
