validate_aws_sns_message

Licence: MIT
Quick start
pip install validate_aws_sns_message
import validate_aws_sns_message
# Raise validate_aws_sns_message.ValidationError if message is invalid.
validate_aws_sns_message.validate(decoded_json_message_from_sns)
Gotchas
The validate function downloads the signing certificate on every call. For performance reasons, it's worth caching certificates - you can do this by passing in a get_certificate function.
This takes a url, and returns the certificate content. Your function could cache to the filesystem, a database, or wherever makes sense.
