# Catalog API: Enumerate Products This sample uses the [AWS Marketplace Catalog API](https://docs.aws.amazon.com/marketplace-catalog/latest/api-reference/welcome.html) to enumerate your products in the AWS Marketplace catalog. To run the sample, set `AWS_ACCESS_KEY_ID`, `AWS_SECRET_ACCESS_KEY`, `AWS_SESSION_TOKEN` and `AWS_REGION`. ``` $ bundle exec ruby enumerate-products.rb ```
