trial-license-service

The trial-license-service (t-l-s) is a stand-alone service (not deployed with A2) that vends trial licenses in exchange for basic contact information. It plays a part in enabling a low-friction trial experience for A2. When a user installs A2 and doesn't apply a license, the A2 web UI presents a modal offering a trial. The user enters name and email address. The system sends this info to t-l-s which reaches out to the license-generation-service to obtain a new customized trial license and sends the contact information to our marketing data system (Marketo).

Here's the call sequence at play:

Generating licenses via license-generation-service

Today, the license-generation-service lives outside of the a2 repo. This helper script describes the API and auth.

  • Set type to "trial".
  • Set customer to "$first $last <$email>"
  • ? Set customer_id to "$deployment_id" (and possibly also set customer_id_version to 2 ?)
  • ? Do we want to attempt to make further use of entitlements? We could set name to "trial", measure to "days", and limit to "60".
  • Ensure that start is now and end is now + 60 days

Deployment considerations

  • Must be proper TLS
  • Prevent access from embargo countries.
  • Do we need to process email address to further identify embargo country?
