This solution deploys AWS Marketplace Serverless Software as a Service (SaaS) Integration on the Amazon Web Services (AWS) Cloud. Registered AWS Marketplace sellers can use it to deploy a lightweight serverless option for integrating new SaaS listings.

The solution fulfills the core capabilities required to integrate a vendor’s SaaS solution with its corresponding listing on AWS Marketplace. These capabilities include accepting new customer registrations, granting and revoking customer access, updating customer entitlements, and reporting metered usage.

The template provided with the solution supports a contracts-only deployment, a subscription-only deployment, or a full deployment that supports both contracts and subscriptions.
